JHL7440 概要
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.

主な用途
JHL7440 の用途: 6 件s: Thunderbolt 3 NVMe SSD Enclosures, Thunderbolt 3 Docking Stations, External PCIe/eGPU Enclosures, Thunderbolt 3 Add-in Cards (AIC), USB-C Port Expanders / Hubs, Broadcast / Video Production Systems.
Thunderbolt 3 NVMe SSD Enclosures
The JHL7440's 40 Gbps Thunderbolt 3 bandwidth (PCIe 3.0 x4 tunneling) makes it ideal for M.2 NVMe SSD enclosures that target sustained 1.5-2.8 GB/s sequential reads. With 4.5 W peak power and a BGA-337 14 x 14 mm footprint, the IC integrates Thunderbolt 3 + USB 3.1 + DP 1.4 in a single chip, reducing BOM by 30-40% versus discrete multi-IC implementations. Unlike the ASM2464 (20 Gbps USB4), the JHL7440 supports full PCIe tunneling over TB3, enabling native NVMe drivers and eGPU scenarios. Real-world designs (Acasis TBU401, Wavlink UTA21D) bond the controller to an aluminum chassis for thermal dissipation; recommended partners are Phison E16/E18 PCIe 4.0 NVMe bridges and Silicon Motion SM2262EN controllers.
おすすめ
Thunderbolt 3 Docking Stations
The JHL7440 supports dual 4K @ 60 Hz (DisplayPort 1.4 HBR3) or single 8K @ 60 Hz (DSC) downstream via DP-Alt mode on the same USB-C cable, making it the controller of choice for professional Thunderbolt 3 docks that need both video and data on one cable. Integrated USB PD 3.0 at 100 W allows the dock to charge the host laptop while tunneling PCIe for external storage and graphics. The typical TB3 dock places the JHL7440 on a daughter card with an external 120 W PSU; the controller is paired with a TI TPS65988 PD controller for negotiation and a Parade PS186 for HDMI/DP conversion. Performance: 5K single @ 60 Hz with one USB-C TB3 cable delivering full 40 Gbps.
おすすめ
External PCIe/eGPU Enclosures
For eGPU enclosures using Thunderbolt 3, the JHL7440 bridges 4 lanes of PCIe 3.0 from the external GPU to the host at 40 Gbps. End-to-end latency measures 1.6-2.4 ms over TB3 compared to 200-500 us on a native PCIe x16 slot, so the JHL7440 is positioned for workloads tolerant of mild latency (games, rendering, compute kernels) rather than real-time networking. Combined power draw of GPU + JHL7440 typically warrants a 550-650 W internal PSU. The IC's HDCP 2.2 and DisplayPort 1.4 also enable an integrated video passthrough stream from the GPU to the host display, supporting G-Sync and HDR pipelines over a single cable.
おすすめ
Thunderbolt 3 Add-in Cards (AIC)
The JHL7440 powers PCIe 3.0 x4 Thunderbolt 3 add-in cards that retrofit non-TB3 motherboards with a USB-C TB3 port. The typical AIC layout places the JHL7440 face-down on the card with an exposed thermal pad bonded to the bracket plate, since the IC dissipates 4.5 W peak during sustained throughput. Firmware/BIOS compatibility is the critical design constraint: cards may require UEFI updates and Windows/Linux TB3 driver packages for hot-plug event handling. This application is where the JHL7440 sees highest volume (the AliExpress 2018-2022 industrial retro-fit ecosystem cited JHL7440 as the standard for H61/B75/Z97 chipset motherboards).
おすすめ
USB-C Port Expanders / Hubs
USB-C port expanders based on the JHL7440 provide downstream USB 3.1 Gen 2 ports (10 Gbps) plus DP-Alt mode video at the same connector, while the upstream port acts as a Thunderbolt 3 host port for high-speed devices. The IC's integrated 4-port PCIe 3.0 switch allows multiple downstream TB3/USB-C ports on a single Thunderbolt host — useful for chassis manufacturers that want to expose 2-3 USB-C ports from one 40 Gbps uplink. HDCP 2.2 and USB-PD 3.0 are functional in this mode, enabling IT-managed USB-C hubs for enterprise docking. Design tip: keep a 100 uF polymer capacitor on each downstream VBUS rail to satisfy TB3 hot-plug surges.
おすすめ
Broadcast / Video Production Systems
For video editing rigs that ingest 4K/8K RAW over TB3 from external storage, the JHL7440 sustains 1.5-2.5 GB/s JBOD throughput via PCIe tunneling, fast enough for ProRes 4444 XQ 8K playback from an external NVMe RAID. The IC's DisplayPort 1.4 HBR3 capability also supports 8K @ 60 Hz single-tether or dual 4K @ 60 Hz multiviewer setups directly from the Thunderbolt dock. Studio deployments pair the JHL7440 with an HP Z Turbo Drive Quad Pro enclosure or a Sonnet Echo Express for high-bandwidth craft editing. Low bit-error-rate and HDCP 2.2 are critical for broadcast preview/QC workflows.

設計ノート
Estimated: at peak throughput (40 Gbps, sustained), the JHL7440 dissipates 4.5 W from a 14 x 14 mm BGA-337 package. Without active cooling, junction temperature will exceed 105 C within minutes and trigger the IC's internal thermal shutoff. Bond the die pad to a 100 cm² copper plane, a 15 x 15 mm aluminum heatsink, or a thermally-conductive chassis. In tested designs (Acasis TBU401, Wavlink UTA21D), the heatsink-to-chassis thermal path provides approximately 3-4 C/W thermal resistance, which is sufficient for sustained workload but not for purely passive operation.
The JHL7440 requires multiple voltage rails: 0.95 V core, 1.8 V I/O, 3.3 V USB-PD, and 5 V/20 V VBUS for USB Power Delivery up to 100 W. Recommended sequencing is 0.95 V first, then 1.8 V, then 3.3 V — failure to follow this order can cause USB-PD controller hand-shake failures and erratic TB3 link-up. Use low-ESR ceramic capacitors (10 uF X7R or better) on each rail within 5 mm of the BGA balls, and isolate the analog 0.95 V core from the digital I/O 1.8 V with a ferrite bead to suppress switching noise injection into the Thunderbolt PHY.
BGA-337 with 0.65 mm pitch requires HDI PCB stackup: 6 layers minimum (signal-gnd-pwr-gnd-signal-pwr) with 0.076 mm trace/space for the BGA escape. Use microvias (laser-drilled) for breakout; through-vias on inner pads are not recommended. High-speed TB3 traces must be length-matched within 0.13 mm (5 mil) tolerance and routed with 100 ohm differential impedance. Place the crystal/oscillator within 5 mm of the BGA; length tolerance ±1 mm. Keep the PCIe 3.0 x4 upstream traces length-matched to within 0.5 mm to preserve lane-to-lane deskew.
Common pitfalls: (1) Sharing the 1.8 V LDO between the JHL7440 and downstream USB-PD controller causes noisy power-up handshakes — use a dedicated LDO per rail. (2) Placing decoupling capacitors on the wrong side of the BGA (rather than directly beneath the power balls) creates 50-100 ns of supply ringing. (3) Routing the TB3 differential pairs over a power-plane split causes impedance discontinuities and link-training failures. (4) Forgetting the firmware pull-up on the SMBUS pins can prevent USB-PD controller initialization on cold boot.
