DS90LV019TMX - 100 Mbps LVDS Transceiver | Texas Instruments
MPN: DS90LV019TMX ✓ פעילDS90LV019TMX סקירה
An LVDS transceiver is an interface IC that combines a current-mode differential transmitter with a differential receiver. In the transmit direction, the device converts a single-ended TTL/CMOS signal into a balanced LVDS pair. In the receive direction, it converts the differential voltage on that pair back into a single-ended logic signal. This interface belongs to the line-driver and transceiver hierarchy within interface ICs and is suited to links where low signal current, noise immunity, and ground-noise rejection are important.
The device operates from either 3.3 V or 5.0 V, giving designers flexibility across low-voltage and legacy logic systems. Its nominal data rate is 100 Mbps, while the driver produces a 3.5 mA output loop current. The balanced differential signaling method reduces sensitivity to common-mode noise and permits reliable data transfer over point-to-point interconnects when the board, connector, and cable geometry meet the interface requirements.
The DS90LV019 includes independent driver and receiver functions with TTL/CMOS-compatible DIN and ROUT logic interfaces. Its flow-through pin arrangement supports direct signal routing between logic circuitry and connector or transceiver pins. The arrangement can simplify PCB routing and shorten stub lengths, although designers should still follow the manufacturer's pinout and recommended layout because high-speed differential signals require controlled impedance and symmetrical routing.
Typical uses include point-to-point links between FPGA or ASIC test equipment, industrial control modules, data-acquisition systems, video-interface subsystems, and embedded processing boards. The 14-pin SOIC format also makes the device practical for designs that need a conventional small-outline surface-mount package rather than a fine-pitch array or exposed-pad package.
A key implementation consideration is that LVDS performance depends on the complete transmission path, not only the transceiver. Use a controlled-impedance PCB connection, maintain a consistent differential trace geometry, provide a proper ground reference, and minimize unterminated branches. Verify that the connected logic levels, cable length, connector structure, and receiver load are compatible with the manufacturer's operating recommendations.
This product record combines the device's principal interface characteristics with practical selection guidance, package information, and verified drop-in alternatives. It is intended to help engineers identify the correct supply configuration, logic interface, data-rate requirement, and replacement before beginning layout or prototype assembly.

יישומים טיפוסיים
DS90LV019TMX מתאים עבור 6 יישוםs: FPGA-to-FPGA Point-to-Point Link, Industrial Control Data Link, Data-Acquisition Module Interface, Test and Measurement Instrumentation, Embedded Processor Communication, Video Interface Subconnection.
FPGA-to-FPGA Point-to-Point Link
The DS90LV019TMX fits a direct differential connection between two FPGA boards when the required nominal rate is 100 Mbps and the logic interface is compatible with 3.3 V or 5.0 V operation. Its independent driver and receiver allow the transmitting and receiving paths to be used separately on each endpoint. The 3.5 mA current-mode output supports low-power LVDS signaling, while the 14-pin SOIC arrangement can simplify assembly compared with fine-pitch devices. The PCB connection should use a controlled differential impedance, continuous reference plane, symmetric routing, and minimized branch lengths. Confirm timing margins, connector loss, and receiver thresholds for the actual board-to-board distance.
מומלץ
Industrial Control Data Link
The DS90LV019TMX is suitable for a low-power industrial control link carrying commands or status data between controller and peripheral modules. Single-supply operation from 3.3 V or 5.0 V supports both modern controller rails and established industrial logic levels. Differential LVDS signaling improves immunity to common-mode interference compared with a single-ended connection when the physical implementation follows good signal-integrity practice. Its nominal 100 Mbps rate provides more capability than many low-speed control links. The design should account for cable length, connector geometry, grounding, and system-level surge or transient requirements rather than assuming that balanced signaling alone covers every industrial EMC requirement.
מומלץ
Data-Acquisition Module Interface
The DS90LV019TMX can connect an acquisition or processing module to a controller through a balanced LVDS link, providing one transmit and one receive function on each device. The 100 Mbps nominal rate accommodates synchronized control, status, and moderate data traffic, while the 3.3 V or 5.0 V supply flexibility allows integration with multiple logic platforms. Differential routing reduces susceptibility to ground-potential differences when the link spans modules or includes a connector. For acquisition systems, preserve analog and digital separation, use a suitable return path, and test the complete transmitter-to-receiver channel with the intended cable and connector because component specifications alone do not determine end-to-end eye margin.
מומלץ
Test and Measurement Instrumentation
The DS90LV019TMX is applicable to point-to-point control and data paths inside modular test and measurement equipment. Its independent transmitter and receiver support full-duplex-style communication between instrument modules, while differential signaling helps maintain data integrity around switching regulators, clocks, and analog circuitry. The 14-pin SOIC package supports conventional surface-mount assembly and the flow-through pin arrangement can make connector routing more direct. Designers should keep the LVDS pair away from high-energy analog inputs and switching-node paths, use controlled impedance, and evaluate cable or connector bandwidth at the intended data rate. The exact logic thresholds and propagation timing must remain compatible with the controller driving the interface.
מומלץ
Embedded Processor Communication
The DS90LV019TMX can bridge a processor-based embedded system and an external high-speed peripheral through a balanced differential connection. Its nominal 100 Mbps rate is appropriate for moderate-bandwidth command, status, and data transfers, while the 3.3 V or 5.0 V operating range provides broad logic compatibility. The transceiver separates the LVDS physical channel from the single-ended digital interface, allowing the processor to use ordinary CMOS signaling. Layout must preserve differential symmetry and return-current continuity across board splits, connectors, or cables. Verify processor I/O voltage, setup and hold requirements, and receiver-output timing before enabling the link at the system's maximum intended data rate.
מומלץ
Video Interface Subconnection
The DS90LV019TMX can support auxiliary or point-to-point connections within a video-processing system when the link carries a signal rate consistent with its nominal 100 Mbps capability. Differential signaling is useful in video equipment because it reduces common-mode noise pickup and provides a controlled interface between boards. The flow-through pinout can simplify routing from logic sections toward connectors or other interface devices. Video designs should separate the LVDS route from display drivers and analog video paths, maintain uniform impedance, and inspect the receiver output for adequate setup and hold margin. For higher-resolution or higher-rate video links, select a transceiver explicitly specified for that data rate rather than treating this device as a universal video interface.

הערות תכנון
Route the differential LVDS pair as a controlled-impedance transmission line with consistent spacing and width over a continuous reference plane. Keep the pair symmetrical through vias, bends, test pads, and connector transitions, and avoid stubs that create reflections. The manufacturer's flow-through pin arrangement can simplify the connection sequence, but it does not remove the need to minimize branches and preserve return-current continuity across board splits.
Validate the complete channel rather than only the IC pins. Include the PCB geometry, connector, cable or trace length, receiver loading, and logic-device capacitance in simulations or measurements. Start with the manufacturer application circuit and termination arrangement, then examine receiver output timing and eye margin at the intended 100 Mbps nominal rate. Any alternative must be checked against the same channel requirements.
Place supply bypassing close to the device's power and ground pins and keep return currents within the device's ground path. Use the capacitance and layout specified by the manufacturer datasheet because excessive or insufficient decoupling can alter switching and transient performance. A single 3.3 V or 5.0 V supply is supported, but the selected voltage must match both the external network and the connected TTL/CMOS logic interface.
Do not treat a same-package ordering suffix as proof of unconditional interchangeability. Compare the exact pin descriptions, propagation delay, receiver thresholds, differential output limits, operating temperature, and lifecycle status before replacing the target. Also avoid assuming that 100 Mbps is acceptable for every physical link; connector and cable bandwidth, trace losses, clocking, and system timing margin determine whether the end-to-end channel remains reliable.
