DS90LV049HMT - 400Mbps LVDS Dual Driver/Receiver Pair, 16-TSSOP
MPN: DS90LV049HMT ✓ فعالDS90LV049HMT نمای کلی
An LVDS (Low Voltage Differential Signaling) transceiver is a signal-conditioning device that converts single-ended CMOS logic into a low-voltage differential pair and back again. In the signal-chain hierarchy it sits between a digital controller and a physical link: LVDS transceiver -> differential line interface -> interface IC -> semiconductor. Because the differential output swings only about 1.2 V across a 100 ohm differential load, the signal is inherently noise rejecting and low EMI, which is why the technique dominates high-speed backplane, video, and industrial communication links.
Key features of the DS90LV049HMT include data rates in excess of 400 Mbps, a single 3 V to 3.6 V supply rail, LVTTL/LVCMOS-compatible driver inputs, low power dissipation, and exceptional noise immunity. The flow-through pin arrangement lets inputs and outputs exit on opposite package sides, so traces run straight through the device without crossing, which simplifies routing on two-layer and four-layer boards. The H suffix denotes the high-temperature grade, extending the operating range to +125 °C for harsh industrial environments.
Internally, the device uses CMOS differential stages for both the driver and receiver sections. The driver converts a single-ended CMOS input into a balanced pair, and the receiver re-differentiates the incoming pair back into a clean CMOS output. This architecture gives constant low power dissipation across data rates and immunity to common-mode noise injected along the cable or PCB trace, which matters in environments with motor drives, relays, and switching supplies nearby.
Typical uses include point-to-point and dual-drop LVDS links between FPGAs, DSPs, and serializers, industrial control and test instrumentation backplanes, video timing and transport links, and any high-speed control interconnect where ground bounce and radiated noise would otherwise corrupt a single-ended clock or data line.
When laying out a board around this device, keep the differential pair impedance-controlled and matched, terminate the far end exactly as the datasheet recommends, and reserve solid ground-plane return beneath the pair. Because the part is a flow-through package, route inputs and outputs on opposite sides of the package so no stub or crossover is introduced on the high-speed nets.

کاربردهای معمول
DS90LV049HMT مناسب است برای 6 کاربردs: FPGA-to-FPGA High-Speed Point-to-Point Links, Industrial Control and Test Instrumentation Backplanes, Video and Imaging Data Transport, Sensor and Smart-Home IoT Edge Nodes, Aerospace and Defense Avionics Interconnects, Medical and Diagnostic Equipment Data Buses.
FPGA-to-FPGA High-Speed Point-to-Point Links
The DS90LV049HMT fits FPGA fabric-to-fabric interconnect where the link must exceed 400 Mbps and the two boards are separated by a connector or a long backplane trace. Its LVDS differential output swings only about 1.2 V across the standard 100 ohm termination, which rejects common-mode noise from switching power stages and cuts radiated emissions compared with a single-ended CMOS link. With two drivers and two receivers in a single 16-pin TSSOP, a bidirectional pair between two FPGAs is built from one device instead of separate transmit and receive parts, saving board area. The flow-through pin arrangement lets the incoming differential pair enter on one package side and continue on the other, keeping trace geometry matched and the routing free of crossovers on two-layer and four-layer stack-ups.

Industrial Control and Test Instrumentation Backplanes
Instrumentation and machine-control cabinets combine slow sensor conditioning with fast multiplexed data, and the DS90LV049HMT carries the fast portion across the backplane. The -40 °C to +125 °C operating range covers equipment mounted in hot cabinets, near motor drives, or in temperature-controlled test fixtures. The exceptional noise immunity and ultra low power dissipation of the CMOS core mean the link keeps working beside relays, contactors, and switching converters where a single-ended line would pick up ground bounce. The 3 V to 3.6 V single supply also lets the device share the same 3.3 V rail as the controller logic, eliminating level translators at both ends of the link.

Video and Imaging Data Transport
Video timing, sync, and pixel-parallel compression data are often distributed over several metres between a processor board and a display or camera head. The DS90LV049HMT delivers these signals as LVDS pairs above 400 Mbps, so multiple streams can share a cable without the crosstalk and ground-offset problems of parallel single-ended buses. Because the driver output is a small differential swing rather than a rail-to-rail CMOS edge, emissions stay low enough to pass through shielded connectors and dense cable bundles. The receiver section restores clean CMOS levels for the display controller, and the +125 °C rating suits cameras and panels mounted in sealed enclosures with limited airflow.

Sensor and Smart-Home IoT Edge Nodes
Distributed sensor nodes in smart building and factory monitoring systems often sit meters from the edge gateway, and low-cost wiring makes a robust physical layer essential. The DS90LV049HMT provides that layer at very low power dissipation, which matters when the node budget is dominated by a small battery or energy-harvesting supply. LVDS immunity to the common-mode spikes generated by relay-driven actuators and dimmable LED drivers means the link keeps integrity in electrically aggressive environments. The device accepts standard LVTTL/LVCMOS from small MCUs and directly drives the differential pair, keeping the node BOM to a single transceiver and a handful of passive terminations.

Aerospace and Defense Avionics Interconnects
Avionics and ruggedized ground-support systems need data links that keep margin over long cable runs with severe EMI. The DS90LV049HMT's LVDS physical layer provides the noise rejection and low emissions that differential signaling was designed for, and the -40 °C to +125 °C range covers unheated equipment bays and thermal-qualified boxes. Dual driver and receiver channels let a single package carry redundant or bidirectional paths, which is valuable where a link must be monitored in both directions. The flow-through TSSOP package also supports the dense, disciplined layout that flight-critical boards demand, since matched differential routing can be maintained without layer changes.
پیشنهادی
Medical and Diagnostic Equipment Data Buses
Diagnostic analysers and patient-monitoring carts route high-rate sample data between acquisition boards, a processor, and display modules over cables that may run adjacent to switching and motorised subsystems. The DS90LV049HMT suits this use because LVDS rejects the common-mode interference such cables pick up, while the low power dissipation keeps thermal rise inside densely packed enclosures acceptable. The extended temperature rating supports devices that must be qualified across a wide ambient range during validation. The receiver output is standard CMOS, so it drives the FPGA or DSP acquisition engine directly without additional interfacing stages.

یادداشت‌های طراحی
The DS90LV049HMT is a flow-through device, so bring the differential pairs into the pins on one package side and let the traces exit on the opposite side. Keep the LVDS pair as a tightly coupled, length-matched pair over a continuous ground plane, avoid stubs, and minimize vias, because any discontinuity in the pair unbalances the differential impedance and degrades the noise rejection that makes LVDS worthwhile. Use the pin description table in the TI DS90LV049H datasheet to confirm which pins are inputs, outputs, enable, and reference.
Apply the differential termination network recommended in the manufacturer datasheet at the far end of each channel, and confirm the link budget for your cable length and data rate rather than assuming the >400 Mbps headline figure holds in your system. Any single-ended stub or test-point tap on the differential pair should be eliminated or heavily damped. Keep the driver outputs away from clocks, inductors, and switching nodes, and route them on an outer layer with an uninterrupted reference plane directly beneath.
Place the supply bypass capacitor immediately adjacent to the VCC pins and provide a solid ground-plane connection on the opposite side of the board to keep the return path short. The DS90LV049HMT consumes very little power, so its own dissipation is rarely the limit, but the 3.3 V rail feeding it must stay quiet if the link depends on the exceptional noise immunity of the device. A dedicated low-noise regulator section, isolated from switching converters, gives the best margin.
Do not substitute a transmit-only quad driver such as the DS90LV031AQML family for this part: the pin functions and channel count differ, and the receiver path would be lost. Likewise, confirm the enable and reference pin states on your schematic before power-up, since an incorrect bias can leave the outputs in an undefined state during ramp. Finally, verify the tube-packaging quantity and pick-and-place orientation against the mechanical drawing, since the flow-through body is easily mirrored on a TSSOP footprint.
