DS90LV019TM - 3.3V/5V LVDS Transceiver | Texas Instruments
MPN: DS90LV019TM ✓ AktifDS90LV019TM Genel Bakış
An LVDS transceiver is an interface IC that converts a single-ended logic signal into a low-voltage differential pair on the transmit side and converts a received differential pair back into a single-ended logic signal on the receive side. In the signal-chain hierarchy, DS90LV019TM is an LVDS interface transceiver, belonging to the broader interface-IC and data-communications semiconductor categories. Its differential signaling is associated with the EIA-644-A and TIA-644-A technologies identified in the verified component data.
Key features include independent operation of the driver and receiver, support for both 3.3 V and 5 V supplies, and a 3.5 mA LVDS output loop current. The 14-pin SOIC package uses a flow-through pin arrangement that permits short PCB routing between device pins and an external connector. A maximum data rate of 100 Mbps makes the device suitable for moderate-speed point-to-point links rather than very high-speed multimode channels.
The architecture uses a current-mode differential driver to maintain controlled output current while transferring data across a balanced connection. Because the two transmission lines carry complementary signals, external circuitry reconstructs the logic state from their voltage difference. This approach can reduce sensitivity to common-mode noise relative to an unbalanced single-ended link, provided the receiver termination, connector, and cable geometry satisfy the interface requirements.
Typical uses include industrial control links, test and measurement equipment, computer peripherals, video or display interconnects, and embedded systems that need a compact LVDS point-to-point interface. Because the driver and receiver are independent, a board can transmit and receive over separate balanced pairs. The 14-pin SOIC package is also suitable for conventional surface-mount PCB assembly where sufficient copper and solder mask clearance are available.
Designers should preserve the flow-through routing advantage and keep LVDS traces short, properly terminated, and referenced to a continuous ground plane. Input and output logic levels must remain compatible with the selected 3.3 V or 5 V supply. Because the supplied excerpts do not provide a verified pin-number-to-pin-name table, the pinout is intentionally left unpopulated rather than presenting inferred connections as authoritative data.
This page combines verified manufacturer and distributor information, package details, interface characteristics, application guidance, and strict drop-in equivalence analysis. It also distinguishes electrically similar parts that use a different package and therefore cannot be treated as true PCB drop-in replacements.

DS90LV019TM için uygundur 6 uygulamas: Industrial Point-to-Point Control Links, Test and Measurement Interconnects, Display and Video Control Interfaces, Embedded System Communication, Computer Peripherals, Security and Surveillance Equipment.
Industrial Point-to-Point Control Links
The DS90LV019TM fits industrial point-to-point links because it combines one differential driver and one receiver with operation from a single 3.3 V or 5.0 V supply. Its verified 100 Mbps data-rate capability provides useful margin for controller, sensor, and peripheral connections that are shorter than a broad backplane. The transmitter drives a balanced LVDS pair at a controlled 3.5 mA loop current, while the receiver returns a TTL/CMOS-compatible signal to the host logic. In a cabinet or factory system, differential signaling can improve rejection of common-mode interference when the pair is routed with continuous ground reference. The flow-through 14-pin SOIC arrangement also helps keep traces short between the transceiver and a connector, although termination, pair symmetry, and electromagnetic-compatibility requirements must still be validated for the final installation.
Test and Measurement Interconnects
DS90LV019TM is appropriate for test and measurement equipment that needs a compact, low-power differential link between an instrument controller and a peripheral. The verified 100 Mbps rate is sufficient for many status, command, and digitized-control paths, while the independent driver and receiver allow one board to transmit and receive simultaneously over separate pairs. TTL/CMOS-compatible interfaces simplify connection to digital controllers, and support for both 3.3 V and 5 V supplies accommodates mixed legacy and modern logic systems. Its 14-pin narrow SOIC package preserves conventional surface-mount assembly, while the flow-through arrangement can reduce connector-routing distance. Signal-integrity verification remains essential: impedance, differential termination, pair length matching, and return-path continuity determine whether laboratory cabling or internal wiring preserves useful eye margin.
Display and Video Control Interfaces
The DS90LV019TM can support short display and video-control connections where a compact point-to-point differential interface is preferred. The device’s one-driver, one-receiver arrangement suits control traffic, low-rate auxiliary data, and distributed display endpoints rather than high-resolution video payload transport. At the verified maximum rate of 100 Mbps, the key benefit is balanced LVDS signaling with separate TTL/CMOS-side logic rather than raw multimedia bandwidth. The 3.3 V or 5 V supply flexibility accommodates controller and panel logic, and the 14-pin SOIC package leaves room for a compact panel interface. Engineers should keep the differential traces tightly coupled, provide the required receiver termination, and verify connector and cable losses before assuming that a nominal 100 Mbps source rate is reliable end to end.
Embedded System Communication
DS90LV019TM is useful as an embedded-system communications bridge between a controller and a remote module, sensor, or human-interface board. TTL/CMOS-compatible logic reduces the need for a separate line-driver stage, and the single 3.3 V or 5 V supply supports multiple embedded platforms. Its differential LVDS link can provide better common-mode noise immunity than a long single-ended connection when the PCB or cable pair is properly implemented. The 100 Mbps verified data rate handles command, telemetry, and status traffic efficiently, while independent transmitter and receiver paths support bidirectional communication. The flow-through pin arrangement is useful in constrained boards because it enables direct routing toward connectors. Firmware or hardware handshaking and protocol timing must still be designed around the actual channel margin rather than the headline data rate alone.
Computer Peripherals
The DS90LV019TM can serve older and newer computer-peripheral interfaces requiring a short, robust differential connection. Its TTL/CMOS compatibility supports conventional digital logic, and its 3.3 V or 5 V operation allows implementation around both legacy 5 V controllers and 3.3 V systems. The differential driver provides a controlled 3.5 mA loop current, while the differential receiver supports noise-tolerant point-to-point communication. At up to 100 Mbps, the interface is appropriate for control, status, and lower-rate synchronized data rather than high-volume storage traffic. The narrow 14-pin SOIC footprint is practical for compact peripheral boards, and its flow-through arrangement helps minimize the distance between the transceiver pins and a connector or cable attachment. Production designs should confirm standards compliance and signal integrity for their particular cable and enclosure.
Security and Surveillance Equipment
DS90LV019TM can connect control and status information between a surveillance-system controller and a distributed camera or sensor module. Balanced differential signaling is attractive in equipment that may sit near motors, power converters, or other sources of common-mode interference because it can reduce sensitivity to noise relative to an unbalanced link. The verified 100 Mbps rate is well suited to command, configuration, and event signaling, while TTL/CMOS compatibility simplifies attachment to digital controllers. The 3.3 V or 5 V supply choice supports different board architectures, and the 14-pin SOIC package is compact enough for space-constrained camera electronics. Proper grounding, controlled impedance, correct termination, and balanced connector pin assignments remain essential; the transceiver alone does not guarantee regulatory compliance or reliable cable performance.

Tasarım Notları
Use the DS90LV019TM flow-through pin arrangement to keep the LVDS route short between the transceiver and the connector. Route the differential pair over a continuous reference plane with closely matched geometry, avoid split planes and uncontrolled stubs, and keep switching-current loops away from the receiver input. If the connection leaves the PCB, use a connector and cable that preserve differential impedance and pair symmetry. Verify the final channel with an appropriate eye or voltage-versus-time measurement rather than relying only on the nominal 100 Mbps rating.
Do not assume that every electrically similar LVDS transceiver is a PCB drop-in replacement. The supplied cross-reference results name SN65LVDS9638, MC100LVDS9638, and MAX9121 as equivalents, but they do not establish the same 14-pin SOIC footprint and pin functions; their available package descriptions indicate smaller packages. Likewise, DS90LV019TMX is an order or packaging form of the target rather than a distinct engineering alternative. Confirm the package drawing, numbered pins, supply limits, receiver topology, enable logic, and termination requirements before substituting any part.
Implement the receiver termination and connector return path according to the manufacturer interface requirements. For a point-to-point LVDS link, the differential pair should be treated as a controlled-impedance structure, and both conductors should return to the same solid ground reference. Check common-mode voltage and differential swing with the intended cable length. The verified 3.5 mA output loop current describes the transmitter behavior, but useful bandwidth still depends on load, termination, trace loss, connector transitions, and noise margin at the receiver.
Provide a stable 3.3 V or 5.0 V supply and place the required local bypass capacitor close to the device supply and ground pins. Use short ground returns so switching current from the supply network does not share the sensitive receiver-return path. The supplied excerpts do not state the exact recommended capacitor values, input-voltage tolerances, quiescent current, or thermal limits. Use the manufacturer datasheet’s application circuit and power-supply recommendations rather than inferring those values from general LVDS practice.
Uyumluluk Bilgisi
The supplied excerpts reference RoHS and REACH in a comparison page but do not state the compliance result for DS90LV019TM. No automotive qualification is identified, so AEC-Q100 is marked not_applicable.
