The Texas Instruments ISO7760QDBQQ1 is an automotive-qualified, reinforced six-channel (6/0) digital isolator with 100 Mbps signaling rate, 3000 VRMS isolation rating in the DBQ package, and 85 kV/µs common-mode transient immunity (CMTI), housed in a 16-pin SSOP (DBQ) package. It supports 2.25 V to 5.5 V wide supply on both sides, enabling level translation between low-voltage microcontrollers and 5 V peripherals without external shifters. Digital isolators are semiconductor devices that use capacitive, inductive, or optical coupling to transmit data across a galvanic isolation barrier while blocking high voltages. ISO7760QDBQQ1 belongs to the capacitive-coupling family of digital isolators within TI's isolation IC portfolio, occupying the role of "signal-path galvanic barrier" in functional safety architectures (ISO 26262) and reinforced-insulation designs per IEC 60747-17. Reinforced insulation means the device withstands 5 kV RMS / 8 kV peak transient overvoltage, suitable for system-level working voltages up to 600 VRMS. Key features of the ISO7760QDBQQ1 include a low 200 ns typical propagation delay, 1 ns channel-to-channel skew, AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), and UL 1577 / VDE / CSA / TUV / CQC safety certifications. The device consumes 2.5 mA per channel at 5 V and 1 Mbps, significantly lower than optocoupler alternatives, and integrates robust EMC with low EMI emissions, eliminating the need for external shielding on most PCB designs. Internally, the ISO7760 uses TI's proprietary silicon-dioxide (SiO2) capacitive isolation barrier with on-chip differential signaling and refresh. Each channel uses a differential Tx/Rx pair across two capacitors, giving excellent common-mode noise rejection; the SiO2 dielectric is intrinsically radiation-tolerant and provides > 50-year barrier life at rated voltage. A simple CMOS interface eliminates the LED-degradation issues of optocouplers, giving the part a 25-year operating lifetime. Typical applications include EV battery-management system (BMS) communications, traction inverter gate-driver signal isolation, industrial CAN/RS-485 interface isolation, and PLC I/O isolation. Its AEC-Q100 Grade 1 rating makes it suitable for under-the-hood automotive designs where ambient temperature exceeds 100 °C. When designing, route input and output supply rails with 0.1 µF bypass capacitors placed within 2 mm of the VCCx pins, and keep high-dV/dt traces (gate drivers, motor phases) at least 8 mm away from the barrier side to maintain 85 kV/µs CMTI margin.

The ISO7761 is fabricated on TI's proprietary silicon-dioxide (SiO2) capacitive isolation technology, which delivers industry-leading CMTI performance and radiation tolerance. Internal refresh circuitry continuously resynchronizes the output state to the input, eliminating bit errors from CMTI events. The device integrates dc-dc converter interface pins (VCC pins are independent on each side), and all logic I/O pins use Schmitt-trigger inputs for noise immunity. Typical applications include industrial fieldbus isolation (RS-485, CAN, SPI), motor drive gate-driver signal isolation, solar inverter high-voltage interface isolation, PLC analog/digital I/O module isolation, and medical equipment patient-isolation interfaces. The 5/1 channel count matches the typical MCU SPI or UART port arrangement.

Per the manufacturer datasheet, the part delivers 100 Mbps data rate, 85 kV/us minimum common-mode transient immunity (CMTI), and robust EMC performance suitable for noise-prone industrial environments. A digital isolator is a galvanic isolation device that transfers logic signals across a safety isolation barrier using capacitive or magnetic coupling rather than an optocoupler LED. This topology eliminates the aging, CTR degradation, and slow propagation of optocouplers while meeting reinforced insulation ratings. In the system hierarchy, the ISO7761 sits between a logic-level controller (MCU, FPGA, ASIC) and a high-voltage or noisy domain (gate driver, sensor, communication bus), protecting low-voltage silicon from ground-potential differences and fast transients on the field side. Key features include wide 2.25 V to 5.5 V supply range on both sides, default low outputs, low 1.7 mA per channel typical quiescent current at 1 Mbps, and 100 Mbps NRZ signaling with < 12 ns typical propagation delay. The device is certified per UL 1577, IEC 60747-17 (VDE), CSA, TUV, and CQC for reinforced insulation, with 3000 Vrms working voltage (DBQ package) and 5000 Vrms (DW package variant). The SSOP-16 (DBQ) footprint is 5 mm x 4 mm, ideal for compact designs. Internally, the ISO7761 uses TI's silicon-oxide (SiO2) capacitive isolation barrier with on-off keying modulation and differential signaling across the barrier. A refresh circuit on each side periodically re-drives the output to maintain DC accuracy. The high CMTI of 85 kV/us ensures the output does not glitch during fast switching events such as IGBT/MOSFET transitions in motor drive and solar inverter applications. Typical applications include industrial fieldbus isolation (RS-485, CAN, SPI), isolated gate driving for IGBT/MOSFET half-bridges, isolated ADC/DAC signal chains, PLC I/O modules, solar inverter control boards, and medical equipment patient isolation. The wide supply range allows direct interfacing to 3.3 V and 5 V MCUs without level translation. When designing with this device, ensure adequate decoupling on both VCC1 and VCC2 (typically 0.1 uF plus 1 uF bulk) placed within 2 mm of the supply pins. Maintain the creepage and clearance required by your end-equipment safety standard, and confirm that the DBQ package's 8 mm clearance meets your reinforced-insulation voltage needs (use the DW package for 5000 Vrms).

The ISO776x family targets applications that previously needed 6 separate optocouplers. Key differentiating specifications include reinforced 5000 Vrms isolation (DW-16 package), 100 Mbps per-channel signaling, 85 kV/µs CMTI to survive fast switching transients on long motor or bus cables, and ±8 kV HBM ESD on all pins. The wide-body SOIC-16 (7.5 mm creepage) provides the clearance and creepage distances required by IEC 60747-17 (VDE 0884-17) for reinforced working voltage up to 1500 Vpk / 2121 Vpk (per datasheet). Integrated fail-safe default-low or default-high outputs (variant dependent) eliminate external pull resistors. The ISO7761 uses TI's CMOS-based silicon-dioxide capacitive-isolation barrier with on-die edge encoding/decoding, delivering stable channel-to-channel skew of < 5 ns and >100 V/ns dV/dt tolerance. Internally, two separate grounds (GND1 and GND2) allow reference domains on opposite sides of the isolation barrier; power converters on each side are typically bootstrapped with a transformer-driver plus an LDO (e.g., SN6505B + TPS7A47) or a TI integrated isolated DC/DC module. Typical applications include isolated SPI/RS-485/RS-232 interfaces for factory automation, isolated gate drivers for IGBT/MOSFET half-bridges in motor drives and solar inverters, isolated ADC/DAC front-ends for grid protection relays, and battery-management system (BMS) communication in 400 V / 800 V EV traction packs. The reinforced 5000 Vrms rating qualifies it for use across the isolation boundary in medical (IEC 60601-1) and energy-storage (IEC 62933) equipment. When designing with the ISO7761DW, place 0.1 µF bypass capacitors on VCC1 and VCC2 within 2 mm of the device pins, respect the 8 mm minimum creepage on the PCB surface, and ensure the upstream MCU logic-level matches VCCx (2.25 V to 5.5 V). The default-output polarity should be selected to match system reset behavior — ISO7761 (suffix-F) offers default-high for fail-safe high-side driving.

The Texas Instruments ISO7763DWR is a reinforced six-channel digital isolator with a 3/3 forward-channel configuration, 100 Mbps maximum data rate, 85 kV/us CMTI, and 5000 Vrms reinforced isolation in a 16-SOIC DW package. It is designed for high-speed communication between systems operating at different ground potentials, helping protect low-voltage electronics from high-voltage transients. A digital isolator is a semiconductor interface that transfers data across an electrically isolated barrier while minimizing conductive and capacitive coupling between its input and output sides. The ISO7763 belongs to the interface-IC hierarchy and uses capacitive isolation to support signal transmission up to 100 Mbps. Its reinforced isolation rating is intended for applications requiring stronger galvanic separation than basic isolation circuits. The ISO7763DWR provides six digital channels in a 3/3 arrangement, allowing three signals to travel in one direction and three in the opposite direction. Its 5000 Vrms DW-package isolation rating, 85 kV/us common-mode transient immunity, and reinforced construction make it suitable for industrial control, power conversion, communications, and test equipment. The device is specified from -55°C to +125°C according to the manufacturer product details. The principal design considerations are correct supply bypassing, respect for the isolation barrier, propagation-delay behavior, and the package creepage and clearance requirements. The 16-SOIC package is compatible with surface-mount assembly, while the exact pin functions and channel direction must be confirmed from the official datasheet before PCB routing. The default output state of ISO7763DWR is HIGH, which should be considered during power-up and fail-safe system design. Typical applications include isolated SPI or control links in power converters, communication interfaces in industrial equipment, protection between high-side and low-side circuitry, and digital signal isolation between systems with different ground references. Because isolation does not remove the need for careful layout, external protection, and common-mode analysis, the ISO7763DWR should be selected based on voltage, speed, timing, and EMC requirements rather than package appearance alone. This page consolidates the verified ISO7763DWR specifications, package information, sourcing links, and practical selection guidance. It is intended to help engineers identify whether the ISO7763DWR is appropriate for a particular isolated-interface design.
ISO7763FDWR - 6-Channel Digital Isolator, 5kVrms, 100Mbps | TI
The Texas Instruments ISO7763FDWR is a reinforced six-channel digital isolator with 3 forward / 3 reverse (3/3) channel directionality, 5000 Vrms isolation rating (DW package), 100 Mbps data rate, and 85 kV/us typical common-mode transient immunity (CMTI), housed in a 16-pin wide-body SOIC (DW) package. The device uses TI's silicon dioxide (SiO2) capacitive isolation barrier technology and is UL 1577, VDE V 0884-11, CSA, and CQC certified for reinforced insulation. The 'F' suffix denotes the default-high output option while the 'DWR' suffix indicates the 16-pin DW wide-body SOIC tape-and-reel packaging. A digital isolator is a semiconductor device that transfers logic signals between two voltage domains while providing galvanic isolation (no direct current path) up to several kVrms. Digital isolators sit in the signal-chain hierarchy between the sensor/MCU domain and the field-side high-voltage domain, replacing optocouplers with faster edge rates, lower propagation delay, lower dynamic power consumption, and longer operational life. Within the broader taxonomy, ISO7763FDWR is a digital isolator > reinforced isolator > capacitive-isolation isolator > UL 1577 / VDE 0884-11 compliant device > interface IC. Key features include 100 Mbps signaling across all six channels (NRZ), typical propagation delay of 11 ns (5 ns max skew between channels), 1.5 ns pulse-width distortion, and a wide 2.25 V to 5.5 V supply range on each side with level-shifting capability between mismatched rails. The 85 kV/us CMTI prevents data corruption in noisy motor-drive and switching-converter environments, and the 5000 Vrms rating per UL 1577 plus 800 Vpeak working voltage per VDE 0884-11 enable use in 230 V / 400 V industrial systems. An integrated refresh circuit keeps output state stable during missing input edges. Typical applications include isolated SPI / UART / GPIO interfaces in PLCs, isolated gate-drive signal paths for IGBT/MOSFET half-bridges, isolated data acquisition between ADC and MCU, industrial fieldbus (RS-485, CAN, Modbus) isolation, and solar / EV traction inverter gate drivers. The wide-body SOIC provides the creepage and clearance required by end-product safety standards such as IEC 61800-5-1 (adjustable-speed drives) and IEC 61010-1 (measurement equipment). When designing with the ISO7763FDWR, place 0.1 uF decoupling capacitors close to both VCC1 and VCC2 pins, and route the two ground returns (GND1, GND2) as separate planes connected only at the isolator. Avoid placing the device near switching-node edges that exceed its 85 kV/us CMTI margin. This page synthesizes distributor stock, parametric drop-in alternatives, and EMC layout notes not found in the manufacturer datasheet alone, giving the design engineer a single decision-grade reference.
ISO7842FDWW - Reinforced 4-Ch Digital Isolator | TI
The Texas Instruments ISO7842FDWW is a high-performance, reinforced quad-channel digital isolator with a 2/2 channel configuration (two forward, two reverse), designed for robust signal isolation in industrial and automotive systems. It provides 8000-VPK isolation voltage and 5700-Vrms isolation rating, with a wide supply range of 2.25V to 5.5V on both sides, enabling seamless level translation. The device supports signaling rates up to 100 Mbps with a typical propagation delay of 11 ns and a common-mode transient immunity (CMTI) of 100 kV/µs, ensuring reliable data transfer in noisy environments. Housed in a 16-pin SOIC extra-wide body (DWW) package with 14.5 mm creepage, it operates over a wide temperature range of -55°C to +125°C, making it suitable for harsh applications. A digital isolator is a component that provides electrical isolation between two circuits while allowing digital signals to pass across the isolation barrier. It uses capacitive or magnetic coupling to transfer data without a direct electrical connection, protecting sensitive electronics from high voltages, ground loops, and noise. Digital isolators are essential in systems where safety and signal integrity are critical, such as in motor drives, power converters, and medical devices. They replace optocouplers in many applications due to their higher speed, lower power consumption, and better reliability. Key features of the ISO7842FDWW include its reinforced isolation certifications per VDE, CSA, CQC, and TUV, ensuring compliance with international safety standards. The device offers low power consumption, typically 1.7 mA per channel at 1 Mbps, and supports a wide supply range, making it versatile for various voltage domains. Its high CMTI of 100 kV/µs ensures robust operation in environments with fast voltage transients, such as motor drives and inverters. The 2/2 channel configuration provides flexibility for bidirectional communication, and the device is available in both SOIC wide-body (DW) and extra-wide body (DWW) packages. Technically, the ISO7842FDWW uses a capacitive isolation barrier with an on-off keying (OOK) modulation scheme, which provides high-speed data transfer with low propagation delay and skew. The device features an enable pin for output control and a fail-safe mode that defaults to a known state when the input is unpowered. The wide supply range and level translation capability allow direct interfacing with different logic levels, simplifying system design. The device is designed to meet reinforced isolation requirements, providing double protection for safety-critical applications. Typical applications include industrial fieldbus communication, motor drives, power inverters, and isolated SPI/UART interfaces. The ISO7842FDWW is also used in medical equipment, test and measurement instruments, and renewable energy systems where galvanic isolation is required. Its high-speed capability and robust isolation make it ideal for applications demanding reliable data transfer across an isolation barrier. When designing with the ISO7842FDWW, ensure proper PCB layout with adequate creepage and clearance distances to maintain the isolation rating. Place decoupling capacitors close to the VCC pins and follow the manufacturer's guidelines for barrier spacing. The device's high CMTI requires careful attention to layout to minimize parasitic coupling and maintain signal integrity.
IT6263FN/BX - De-SSC LVDS-to-HDMI Converter QFN-64 | ITE
The ITE IT6263FN/BX is a high-performance single-chip De-SSC (De-Spread Spectrum Clocking) LVDS-to-HDMI converter that integrates an LVDS receiver and an HDMI 1.4a transmitter in one package, providing conversion from LVDS input to HDMI 1.4 output. It supports LVDS input clock rates up to 150 MHz, input color depth up to 10-bit, and output deep-color depth up to 12-bit. The device complies with HDMI 1.3, HDMI 1.4a, HDCP 1.2, and DVI 1.0, and accepts single-link or dual-link LVDS data mappings including Open LDI, JEIDA, and VESA formats. A De-SSC LVDS-to-HDMI converter is a specialized bridge IC used in display applications where the source uses an LVDS interface with intentional spread-spectrum clock modulation (used to reduce EMI), but the downstream display only accepts clean HDMI. The IC sits between an LVDS panel-timing generator (SoC, GPU, or media processor) and the HDMI connector, and must transparently remove the SSC modulation so that downstream HDMI timing budgets remain valid. The broader hierarchy is: display bridge converter -> LVDS-to-HDMI bridge -> interface converter -> signal conditioner IC -> semiconductor. Key features include on-chip De-SSC processing (a different value from raw LVDS-to-HDMI bridges such as the IT6261), integrated HDCP 1.2 cipher engine with on-chip keys, dual-link LVDS receiver supporting up to 1920x1200, and an HDMI 1.4a transmitter capable of 1080p60 with 3D-frame-packing support. The part also provides I2C slave control, configurable color mapping, and integrated termination resistors, reducing external component count. The IT6263FN/BX is built on a CMOS mixed-signal process and uses an internal PLL to recover pixel clock and regenerate a clean HDMI TMDS link. Its embedded HDCP hardware engine authenticates the sink device and encrypts the AV stream, making the IC suitable for protected content paths. Internal configurable registers exposed through I2C allow fine-tuning of swing, pre-emphasis, color-depth, and mapping selection. Typical applications include automotive head-unit HDMI outputs from LVDS-SoCs, set-top boxes that repurpose LVDS panels with HDMI repeaters, pico-projectors and LED-projector HDMI bridges, embedded HDMI dongles next to industrial panel controllers, motherboards that need LVDS-to-HDMI for external displays, and digital signage players that interface LVDS media SoCs to HDMI panels. When designing with this part, ensure the LVDS traces are length-matched within the differential-pair tolerance in the datasheet, place a 100 nF decoupling capacitor close to each DVDD pin, and route HDMI TMDS pairs with controlled 100-ohm differential impedance. The embedded HDCP keys require a signed licence from ITE for licensing-protected production runs. This page synthesises distributor pricing, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet summary.
JHL7440 - Intel Thunderbolt 3 Controller | BGA-337
The Intel JHL7440 (also sold as JHL7440 S LMJ2 / JHL7440 S LMHZ) is an Alpine Ridge-based Thunderbolt 3 controller IC that integrates USB 3.1, DisplayPort 1.4, and Thunderbolt 3 (40 Gbps) into a single BGA package, providing four lanes of PCIe 3.0 tunneling and dual-protocol downstream connectivity for docks, NVMe enclosures, and host platforms. A Thunderbolt controller is a high-speed protocol bridge IC that aggregates multiple serial bus standards (PCI Express, USB, DisplayPort) onto a unified 40 Gbps Thunderbolt cable/connector while providing power negotiation via USB Power Delivery. It sits between the platform's internal PCIe/USB/DP lanes and the external USB-C port, enabling a single-cable docking station, eGPU, or NVMe enclosure solution. The JHL7440 belongs to Intel's Falcon Ridge / Alpine Ridge generation and is widely used in add-in cards, NVMe SSD enclosures, and second-generation Thunderbolt 3 docks. Key features of the JHL7440 include: Thunderbolt 3 at 40 Gbps bidirectional bandwidth (4 lanes of PCIe 3.0 bi-directional), native DisplayPort 1.4 with HBR3 support (8.1 Gbps per lane, 32.4 Gbps aggregate for dual-display 8K), USB 3.1 Gen 2 (10 Gbps) backward compatibility, USB Power Delivery 3.0 support up to 100 W downstream, integrated PCIe 3.0 switch with 4 downstream ports, and HDCP 2.2 content protection. The controller targets host platforms that lack native TB3 support and is most commonly deployed on M.2/NGFF key-M add-in cards (TB3 AIC) that plug into a motherboard's PCIe 3.0 x4 slot. Architecturally, the JHL7440 combines a Thunderbolt PHY, a PCIe 3.0 controller, a USB 3.1 controller, a DisplayPort 1.4 receiver/transmitter, a USB-PD 3.0 controller, and an embedded microcontroller into a single 14 x 14 x 1.4 mm BGA-337 package with 0.65 mm pitch. Power consumption is rated at approximately 3.0 W typical / 4.5 W peak, requiring active cooling (heatsink and airflow) for sustained throughput — a common design constraint in NVMe enclosures that must merge TB3 + 10 Gb/s NVMe heat into a small footprint. Typical applications for the JHL7440 include Thunderbolt 3 add-in cards and M.2 NVMe SSD enclosures (40 Gbps), Thunderbolt 3 docking stations with dual 4K or single 8K DisplayPort 1.4 outputs, eGPU enclosures that tunnel x4 PCIe 3.0 to an external graphics card, USB-C port expanders providing downstream USB 3.1 Gen 2 and DP-alt mode, and broadcast / video editing rigs that need high-bandwidth storage bridges. Pin compatibility with JHL6340 (previous-gen) allows retrofit of older TB3 cards after firmware validation. When designing with the JHL7440, allocate a thermal solution capable of dissipating 4.5 W peak — passive heatsinks are marginal in enclosed NVMe enclosures, so forced airflow or a thermally-bonded aluminum chassis is recommended for production designs. Verify firmware/BIOS support on legacy motherboards that lack native Alpine Ridge platform support.
JHL7440-S-LMHZ - Thunderbolt 3 Controller, Dual Port BGA | Intel
The Intel JHL7440-S-LMHZ is a second-generation Thunderbolt 3 controller IC housed in a 337-ball BGA package (FC-CSP, 10.7 x 10.7 mm). It is a Dual Port Device variant from the JHL7440 series, providing two Thunderbolt 3 ports operating at up to 40 Gbps bi-directional bandwidth, with native support for USB 3.1 Gen 2, DisplayPort 1.4, and PCIe 3.0 tunneling. The -LMHZ ordering code designates the specific package, temperature grade, and lead-free / RoHS-compliant configuration used in production designs. A Thunderbolt 3 controller is a high-speed protocol-aggregating interface IC that consolidates multiple peripheral buses (PCI Express, DisplayPort, USB) into a single USB-C cable carrying up to 40 Gbps of combined traffic. Controllers such as the JHL7440 sit between a host system's PCIe/DisplayPort/USB controllers and an external Type-C connector, performing protocol multiplexing, link training, power delivery negotiation (USB PD), and tunneled-stream management. The JHL7440 specifically implements Alpine Ridge-generation features including DP 1.4 alt-mode and USB PD 3.0, and in the Dual Port configuration can drive two Thunderbolt 3 ports from a single chip. Key distinguishing features of the JHL7440-S-LMHZ include 40 Gbps Thunderbolt 3 line rate per port, integrated DisplayPort 1.4 receiver capable of 8K HDR outputs via HBR3 (8.1 Gbps per lane, 32.4 Gbps aggregated), PCIe 3.0 x4 host upstream interface, USB 3.1 Gen 2 (10 Gbps) downstream support, and integrated USB Power Delivery 3.0 controller. The 337-ball FC-CSP package utilizes an exposed-die land-grid array for the shortest possible signal paths to the high-speed SerDes, which is essential for multi-Gbps link training. Typical applications include Thunderbolt 3 docking stations, NVMe SSD enclosures that saturate 40 Gbps pipes, 8K DisplayPort adapters and video capture cards, high-end workstation motherboards, and eGPU enclosures. The Dual Port configuration is especially popular in docking stations where one port connects to a host laptop and the other to downstream peripherals. When designing with the JHL7440, PCB layout must allocate separate reference-clock domains, keep the high-speed TX/RX pairs length-matched within sub-millimeter tolerances, and provide a clean PCIe 3.0 host connection - any signal-integrity issue at 10+ Gbps will surface as Thunderbolt link-training failures. This page synthesizes verified distributor pricing, drop-in alternatives, and practical Thunderbolt 3 design considerations not found in any single distributor catalog.
JHL7440-S-LMJ2 - Intel Titan Ridge Thunderbolt 3 Controller | BGA-337
The Intel JHL7440-S-LMJ2 is the Intel "Titan Ridge" Thunderbolt 3 (Alpine Ridge successor) controller IC, an I/O controller delivered in a 10.7 mm x 10.7 mm BGA-337 package. It implements the Thunderbolt 3 protocol on four PCIe 3.0 lanes and downstream DisplayPort 1.4 muxing, supporting dual 4K@60 Hz DisplayPort 1.4 outputs or one 5K@60 Hz output when paired with an Alpine Ridge-compatible host. The JHL7440 is a peripheral/device-side (LMJ2 suffix denotes the device-mode SKU) Thunderbolt 3 controller commonly used in NVMe SSD enclosures, Thunderbolt 3 docks, and external graphics (eGPU) chassis. A Thunderbolt 3 controller is a high-speed protocol bridge that aggregates PCIe 3.0, DisplayPort 1.2/1.4, and USB 3.1 Gen 2 traffic onto a single Type-C connector using the Thunderbolt 3 alternate-mode physical layer. The JHL7440 belongs to Intel's Titan Ridge (JHL7x40) family, which succeeded the Alpine Ridge (JHL6x40) family and pre-dated the Goshen Ridge (JHL8x40) and Barlow Ridge (JHL9580) controllers. In the wider taxonomy: Thunderbolt controller -> I/O controller -> interface IC -> semiconductor. The "Thunderbolt" word-mark is an Intel-registered protocol distinct from USB4 in its early implementations, although USB4 incorporates the Thunderbolt 3 protocol layer. Key features include 40 Gbps aggregate bi-directional bandwidth (Thunderbolt 3 mode), backward compatibility with Thunderbolt 1/2 over active cables, native USB 3.1 Gen 2 (10 Gbps) support on the Type-C ports, and DisplayPort 1.4 muxing with HDR/REC.2020 support. The device-mode (LMJ2) variant disables the upstream host port and adds a downstream PCIe-only orientation, making it ideal for compact NVMe enclosures where one Type-C port connects to the host and an internal PCIe 3.0 x4 link connects to the NVMe SSD. Firmware is loaded from external SPI flash. In typical applications, the JHL7440-S-LMJ2 sits between an M.2 NVMe SSD (PCIe 3.0 x4) and a Thunderbolt 3 Type-C connector, providing up to ~2.8 GB/s real-world transfer speeds. It is also used in Thunderbolt 3 docks where it functions as a downstream port multiplier connecting to USB 3.1 Gen 2 hubs, SATA controllers, GbE controllers, and audio codecs over PCIe. External GPU enclosures used this controller in early designs before the eGPU market consolidated around Thunderbolt 4 and OCuLink. Designers must route 85-ohm differential pairs for the four PCIe 3.0 TX/RX lanes and the high-speed Thunderbolt SERDES links; the part requires a low-jitter reference clock and a USB Type-C port controller (often a TUSB8041 or discrete CC-logic) to negotiate Thunderbolt mode. Firmware recovery and reflash should be exposed via a vendor-specific procedure because the device-mode SKU will not enumerate as a Thunderbolt host upstream.
JHL7540 - 40 Gbps Thunderbolt 3 Controller | Intel
The Intel JHL7540 is a Thunderbolt 3 controller and USB-C interface IC providing 40 Gbps bidirectional bandwidth in the host-controller role. Verified listings identify the device as a dual-port controller and place it in a 10.7 mm × 10.7 mm FC-CSP BGA package, with JHL7540 S LMHR shown as the tray ordering variant. Its core function is to interface a host system with Thunderbolt 3 and USB-C connections while coordinating high-speed data transfer, power-oriented USB-C behavior, and platform connectivity. A Thunderbolt controller is an interface semiconductor that bridges a computer or embedded platform with Thunderbolt-compatible peripherals. Within the connectivity hierarchy, Thunderbolt 3 uses the physical and protocol capabilities associated with 40 Gbps-class links, while USB-C provides the physical connector used by compatible systems. The JHL7540 is consequently more specialized than a general USB interface controller and is intended for designs requiring the verified Thunderbolt 3 host-controller role. Verified product information identifies USB as the interface type, an I/O-controller classification, dual-port operation, a maximum operating temperature of +65 C, and a minimum operating temperature of 0 C. The package is reported as 10.7 mm × 10.7 mm and supplied in a tray for the JHL7540 S LMHR variant. Other electrical details, including voltage ratings, power consumption, lane configuration details, firmware requirements, and exact electrical limits, are not supplied in the verified web data and should not be inferred. Typical implementation contexts include Thunderbolt 3 host systems, USB-C docking products, high-speed storage peripherals, external display or docking ecosystems, and embedded computing platforms that expose Thunderbolt connectivity. System designers must confirm host-platform support, connector routing, firmware compatibility, signal-integrity requirements, power delivery, and thermal conditions with Intel documentation before releasing a production design. The most important design consideration is that a controller MPN alone does not establish complete Thunderbolt interoperability. The board must implement the required USB-C and Thunderbolt routing, power-management behavior, firmware, connector configuration, and platform interoperability requirements. The verified package information should also be checked against the exact ordering suffix before placing an order. This page consolidates the verified distributor and distributor-indexed product information, while clearly separating missing technical data from confirmed facts. It is intended to support initial sourcing and engineering triage for JHL7540-based Thunderbolt 3 designs.
JHL7540-S-LMHR - Dual-Port Thunderbolt 3 Controller | Intel
The Intel JHL7540-S-LMHR is a dual-port host controller for Thunderbolt 3 connectivity, supplied as the S-LMHR ordering variant in a 337-ball FC-CSP package measuring 10.7 mm by 10.7 mm. Verified listings identify the component as an I/O controller interface IC and Thunderbolt 3 controller, but the supplied sources do not publish a complete electrical parameter table. Consequently, unverified values such as supply voltage, lane count, power consumption, operating temperature, and maximum data rate are not asserted here. A Thunderbolt 3 host controller is a system-level I/O interface semiconductor that coordinates a computer or platform with Thunderbolt-compatible peripherals. It belongs to the I/O controller class, within interface ICs and semiconductors. Thunderbolt technology combines high-bandwidth data transfer, display connectivity, and power delivery over a physical connection, while the controller supplies the platform-facing logic required to manage those functions. The JHL7540 is particularly relevant to desktop, workstation, and embedded Thunderbolt-capable platforms. The verified JHL7540-S-LMHR ordering information establishes dual-port host functionality, Thunderbolt 3 controller classification, FC-CSP construction, tray packaging, and a 10.7 mm by 10.7 mm package. The suffix “S-LMHR” identifies the specific orderable configuration, but its decode and environmental qualifiers are not present in the supplied evidence and should not be inferred. Intel support and specifications pages provide authoritative sources for architecture, platform support, and lifecycle information, while distributor records provide sourcing and package details. Because this controller supports a differential, high-speed interface, PCB design must prioritize short matched routes, continuous reference planes, controlled impedance, and careful connector-to-controller escape routing. BGA assembly also requires stencil, reflow-profile, pad-array, and solder-joint validation appropriate to the manufacturer’s package documentation. Exact layer count, ball-map details, and assembly process requirements must be obtained from the official package drawing before layout release. Potential uses include Thunderbolt expansion chassis, high-resolution external-display systems, professional storage arrays, multi-display workstations, capture systems, and compact desktop platforms. Selection should begin with the host platform’s supported controller generation, firmware support, connector requirements, and Intel platform validation. A different Thunderbolt controller should not be substituted solely because its bandwidth appears similar; electrical, pin, firmware, and platform compatibility must be demonstrated first. This page distinguishes verified ordering and product facts from unknown technical fields instead of filling gaps with assumptions. It also combines the supplied distributor evidence, Intel product resources, and a strict review of available cross-reference results. No pin-compatible replacement was established from the provided data, so any alternative MPN would be misleading until its footprint, pinout, electrical limits, firmware support, and platform behavior are independently verified. The practical sourcing position is straightforward: confirm the Intel documentation revision and platform support, validate the complete 337-ball pin map and FC-CSP land pattern, and compare lead time against the production schedule before committing volume. The known tray package also requires procurement attention because large BGA components can be sensitive to moisture handling, solder-ball condition, and shipping exposure. Engineering release should include distributor traceability, assembly-yield testing, and firmware interoperability checks.
JHL7540-S-LMHS - Dual-Port Thunderbolt 3 Controller | Intel
The Intel JHL7540-S-LMHS is a dual-port host Thunderbolt 3 controller packaged as a 10.7 mm by 10.7 mm FC-CSP and supplied on tape and reel. Its verified source identifies it as Intel's Thunderbolt 3 controller for dual-port host implementations, placing it in the high-speed I/O controller and interface-controller hierarchy. An I/O controller interface IC coordinates communication between a host computing platform and external peripherals. A Thunderbolt 3 controller is a specialized high-speed interface controller that manages Thunderbolt links, connects compatible storage, displays, docks, and other peripherals, and supports the ecosystem of PCI Express and display-oriented connectivity associated with Thunderbolt 3. The exact electrical ratings beyond the verified identity and package information are not supplied in the source data and must be confirmed in Intel's product documentation before design release. The key verified features are dual-port host support, Thunderbolt 3 controller function, FC-CSP construction, a 10.7 mm by 10.7 mm package outline, and tape-and-reel packaging. The LMHS ordering suffix distinguishes the offered supply configuration from the separately listed LMHR tray option. Those suffixes are packaging and ordering identifiers, not evidence of a different controller function. Technically, the JHL7540 belongs in a platform-specific high-speed I/O design rather than a generic serial-interface application. Its implementation role is to provide the controller silicon required by a Thunderbolt-capable host system, while board designers must address power sequencing, high-speed routing, connector requirements, firmware support, and thermal management around the CSP package. The source data does not provide operating voltage, power consumption, signaling rates, temperature limits, pin names, or electrical timing values. Typical uses include Thunderbolt docks, external high-speed storage, workstation connectivity, laptop or desktop platform designs, and other systems requiring dual-port Thunderbolt 3 host connectivity. Suitability depends on validating the associated platform firmware, board layout, power delivery, connector design, and supported operating conditions rather than relying on the distributor category label alone. For a new layout, obtain the official package drawing and pin definitions, confirm the exposed-pad and ball requirements, and route high-speed differential signals as a controlled-impedance interconnect. Treat JHL7540-S-LMHS and JHL7540-S-LMHR as distinct ordering options until the manufacturer's orderable-parts information confirms whether their technical die and package treatment are identical. This page summarizes the verified manufacturer and distributor identity, records unavailable technical fields explicitly, and avoids inventing specifications that were not present in the supplied data. It is intended as an engineering starting point for sourcing and design validation, not as a substitute for Intel's complete controller documentation.
JHL8440 - Thunderbolt 4 Controller | Intel
Intel JHL8440 is a Thunderbolt 4 controller designed for systems requiring high-speed USB4 and Thunderbolt connectivity. The supplied verified data identifies it as a quad-port device in an FC-CSP package, but it does not provide the full electrical, thermal, pinout, or pricing specifications needed for a complete engineering characterization. The available distributor listing describes JHL8440 as an Intel I/O controller interface IC and Thunderbolt 4 controller, while the manufacturer specifications page identifies the same device family. Engineers should use the exact package variant ordering code and the official Intel datasheet before committing a PCB layout or production BOM. A Thunderbolt controller is a high-speed interface IC that coordinates protocol translation, host or device connectivity, DisplayPort integration, and USB4 traffic. In the system hierarchy, it belongs to interface controllers, data-processing semiconductors, and computer connectivity solutions. Thunderbolt 4 builds on the 40 Gbps-class connectivity positioning described in the verified comparison material, but the supplied JHL8440 records do not establish lane count, maximum data rate, power delivery, DisplayPort configuration, host-versus-device operation, supported operating temperature, or power-consumption values. The verified distributor record gives the commercial identifier “JHL8440 S LN6U” and describes an FC-CSP tray package. Another search result identifies the “JHL8440 S LN6V” designation, but the supplied data does not establish whether these ordering codes differ only in packaging, shipment form, or another ordering attribute. Do not treat them as interchangeable without Intel documentation or an authorized distributor’s package cross-reference. The supplied comparison source also mentions RTS5490, JHL7440, JHL7540, and JHL8440 as 40 Gbps-class devices, but it specifically distinguishes RTS5490 as a USB4 hub controller and does not prove drop-in equivalence. Typical system uses for a device in this class include USB4 and Thunderbolt docks, laptop and desktop platform controllers, high-bandwidth storage, external display systems, and compact multiport accessories. These applications are engineering-context suggestions rather than verified Intel reference designs for JHL8440. A production design must confirm signal integrity, power sequencing, firmware support, connector requirements, and thermal performance against the official Intel documentation. This page consolidates the verified manufacturer and distributor references while explicitly marking unspecified technical data as unavailable.
JHL8440-S-LN6U - Thunderbolt 4 Quad Port Controller | Intel
The Intel JHL8440-S-LN6U is a Thunderbolt 4 quad-port host controller in an FC-CSP (Flip-Chip Chip-Scale Package), targeted at high-performance computing platforms that need full Thunderbolt 4 / USB4 routing alongside legacy USB 3 and USB 2 signaling. It implements four Thunderbolt 4 downstream ports that operate at 40 Gbps bi-directional per port (USB4 Gen 3x2), with native support for USB4, DisplayPort 1.4a tunneling (including DSC and Adaptive-Sync), and USB 3.x / USB 2.0 backward compatibility. A Thunderbolt 4 controller is a high-speed multi-protocol I/O router that aggregates PCIe, DisplayPort, and USB-native traffic over a single USB Type-C cable. Within the platform hierarchy, the JHL8440 sits one tier below the CPU's PCIe root complex and bridges the host processor's PCIe 3.0 x4 upstream link to the physical USB Type-C PHYs, providing tunneling, DMA, and protocol multiplexing for every peripheral attached downstream. Compared with its predecessor (JHL7440 / Titan Ridge), the JHL8440 doubles downstream port count from 2 to 4 and mandates DMA protection (VT-d) for all PCIe tunneling, raising the bar for security and dock-level virtualization. Key features include PCIe 3.0 x4 upstream host interface, integrated USB Type-C port logic for four ports, support for up to four 4K DisplayPort 1.4a streams via tunneling, backward compatibility with USB 3.2 and USB 2.0, and Intel VT-d based DMA protection. Intel lanes-internal segmentation supports peer-to-peer traffic between downstream devices without disturbing host CPU cycles. The 'S' suffix indicates the production silicon stepping; 'LN6U' is a sales-channel trim code. Architecturally, the controller uses a multi-protocol mux/switch fabric with hardware DMA engines and a Type-C cable-orientation/poller state machine. It connects to the platform chipset via PCIe 3.0 x4 and exposes standard xHCI/eXtensible Host Controller interfaces for legacy USB, plus USB4 router ports for tunneling. The FC-CSP package keeps the PCB ballout compact and provides controlled-impedance routing for the high-speed serial links required at 20 GHz-class fundamental frequencies. Typical applications include high-end Thunderbolt 4 docks, workstation motherboards with rear-panel TB4 ports, content-creation desktops, eGPU enclosures, professional video-editing rigs, and high-end laptops. The quad-port capability is particularly valuable for docks that fan out to multiple 4K monitors while simultaneously exposing USB 3 and PCIe storage downstream. When designing with the JHL8440-S-LN6U, observe Intel's Thunderbolt 4 platform design guidelines for PCB stackup, AC-coupling capacitor placement on all four high-speed links, and firmware deliverable via the platform's discrete SPI ROM. Treat the part as a single-source controller per platform; lifecycle management is driven by Intel's roadmap. This page consolidates distributor pricing, drop-in alternatives and platform-level design notes not found in Intel's public specifications page, giving procurement and engineering teams a single reference for the JHL8440-S-LN6U.
JHL8440-S-LN6V - Thunderbolt 4 Controller | Intel
The Intel JHL8440-S-LN6V is a Thunderbolt 4 controller for a quad-port device, supplied in an FC-CSP package and tape-and-reel packaging. The verified product data identifies it as an I/O controller interface IC with Thunderbolt 4 connectivity. Its primary role is to provide the system-facing controller silicon required in a compatible Thunderbolt or USB4 storage, docking, docking-station, or peripheral design. A Thunderbolt controller is a high-speed interface controller that coordinates a Thunderbolt link between a host and compatible peripherals. In the system hierarchy, it belongs to interface ICs and semiconductor signal-processing devices rather than a power regulator or processor. Thunderbolt 4 controllers support the physical and logical connection requirements of modern high-bandwidth docks, storage devices, displays, and other peripherals, while the exact protocol features and electrical limits of this part require the Intel manufacturer documentation. The verified distributor listing specifies the JHL8440 as a quad-port device and identifies the package as FC-CSP, with tape-and-reel shipment. Because the supplied data does not include the full package drawing, pin count, pin names, voltage ratings, power consumption, supported host interface details, or operating-temperature limits, those values are not inferred here. The JHL8440-S-LN6V ordering suffix should therefore be checked against the exact Intel documentation and system reference design before layout release. The part is suitable for engineers designing compact Thunderbolt 4 peripherals, especially systems where multiple downstream ports must be coordinated by a dedicated controller. Quad-port capability can simplify product architecture compared with a design using multiple discrete interface devices, although the complete USB4 and Thunderbolt design still requires correct connector routing, signal-integrity control, firmware support, power delivery, and host compatibility. Typical applications include Thunderbolt docks, external storage enclosures, docking stations, high-speed adapters, multi-port peripherals, and workstation or desktop accessories. The controller is placed with the system processor or peripheral controller and supports the physical interface implementation required by the end product. Actual usable bandwidth, port behavior, power delivery, and firmware capabilities must be confirmed from Intel's product documentation rather than inferred from the distributor category. This page combines the verified manufacturer identification, distributor package information, source links, and engineering guidance. It does not fabricate missing electrical specifications, pricing, pinout data, or cross-reference alternatives. Confirm package details and protocol requirements with the Intel datasheet and Intel support materials before committing the design to production.
