DS90LV031ATM - 3V Quad LVDS Line Driver | Texas Instruments
MPN： DS90LV031ATM ✓ 啟用中DS90LV031ATM 概覽
An LVDS line driver is a differential interface component that converts a single-ended CMOS logic signal into two complementary low-voltage outputs. This differential signaling method reduces common-mode noise, lowers electromagnetic emissions, and improves signal integrity over longer point-to-point interconnects. In the broader component hierarchy, the DS90LV031A belongs to the line-driver family, interface IC category, and high-speed digital communication ecosystem.
The principal features of the DS90LV031ATM include four differential drivers, operation from a 3V supply, support for rates above 400 Mbps, and common enable controls for tri-state output operation. LVTTL and LVCMOS input compatibility allows the device to interface directly with common digital logic families. The common EN and EN-bar controls support active-high or active-low output enable management while coordinating all four channels.
The DS90LV031A architecture provides a practical alternative to high-power pseudo-ECL devices in point-to-point interface systems. Differential output signaling improves noise immunity by rejecting noise that appears equally on both output conductors. Its CMOS implementation is intended for systems where data throughput matters more than the very short reach and low logic levels associated with conventional ECL devices.
Typical uses include clock distribution, parallel data links, backplane communication, telecommunications equipment, industrial control systems, and test and measurement instruments. The companion DS90LV032A receiver provides the corresponding four-channel differential receiving function for complete point-to-point links.
PCB layout is critical when operating at LVDS rates. Use controlled-impedance routing, keep differential pairs closely coupled, minimize stub lengths, and place any termination components close to the receiving device. Confirm the output voltage, supply tolerance, propagation delay, and enable timing in the manufacturer datasheet before releasing a high-volume design.
This page organizes the device characteristics, pin and package requirements, application guidance, and verified drop-in alternatives into one engineering reference. It also highlights practical distinctions between the standard, lead-free, and related DS90LV031A ordering codes so that compatibility can be checked before a PCB respin or production release.

典型應用
DS90LV031ATM 適用於 6 應用s: High-Speed Parallel Data Links, Telecommunications Clock Distribution, Industrial Control and Data Acquisition, Test and Measurement Instrumentation, Server and Storage Backplanes, Video and Display Panel Interconnects.
High-Speed Parallel Data Links
The DS90LV031ATM fits parallel point-to-point links where four CMOS signals must be transmitted differentially at rates above 400 Mbps. Each driver converts one LVTTL or LVCMOS input into a complementary LVDS pair, improving common-mode noise rejection and reducing radiated emissions relative to single-ended routing. Place the four differential pairs on controlled-impedance PCB layers and pair each receiver with a termination arrangement appropriate to its input impedance. The 3V supply and common tri-state enable controls also simplify power management when linked channels must be disabled together.
推薦
Telecommunications Clock Distribution
The four independent outputs of the DS90LV031ATM can distribute a high-frequency clock across separate backplanes or cabinet links. Operation above 400 Mbps provides margin for clock rates up to the documented 200 MHz, while differential signaling reduces susceptibility to common-mode noise encountered in telecommunications equipment. The shared EN and EN-bar controls allow all four outputs to enter a high-impedance state together during reconfiguration. Keep clock pairs length-matched, remove unnecessary test stubs, and confirm receiver threshold and timing margins on the connected board.
推薦
Industrial Control and Data Acquisition
The DS90LV031ATM is appropriate for industrial control modules that transfer command, status, or sampled-data signals between circuit cards. LVDS differential outputs help reject noise coupled from motors, relays, switching supplies, and other industrial subsystems, while the 400 Mbps-plus capability supports high-rate digital buses. The 16-pin SOIC package remains compatible with standard surface-mount assembly methods. Use the common enable function to disable the group of drivers when an interface card is idle, reducing activity and simplifying system-level isolation sequencing.
推薦
Test and Measurement Instrumentation
High-speed test systems can use the DS90LV031ATM to drive low-voltage differential signals between instrument modules, daughtercards, and remote fixtures. Its four-channel arrangement consolidates multiple transmitters into one 16-pin SOIC, while the tri-state outputs permit shared-bus connections when a single source must drive at a time. Differential signaling supports cleaner measurements in environments containing switching converters and digital instrumentation. The driver must still be paired with a suitable receiver, and its output timing must be included in the instrument’s acquisition calibration.
推薦
Server and Storage Backplanes
The DS90LV031ATM can provide low-power differential transmission for short, controlled-impedance connections within server or storage backplane subsystems. Its documented rate above 400 Mbps suits narrow parallel interfaces, and differential outputs reduce common-mode coupling from adjacent switching circuitry. The 3V CMOS implementation also offers an alternative to high-power pseudo-ECL solutions where system power is constrained. Validate insertion loss, crosstalk, skew, and receiver equalization across the complete backplane because driver specifications alone cannot guarantee link reach.
推薦
Video and Display Panel Interconnects
The DS90LV031ATM can drive short differential links carrying synchronized digital data or control signals inside multi-panel display equipment. LVDS signaling provides low-voltage, low-emission transmission that is well suited to densely routed internal cables and PCB traces. The four outputs allow one device to serve several related links, while the shared enable pins permit coordinated output states during panel mode changes. Use controlled-impedance routing, account for connector and cable loss, and verify that the selected receiver supports the required pixel or control-data rate.

主要差異化特點
- Closest documented functional equivalent (對比DS90LV031TM)
- Mixed-signal-family alternative with the same physical interface (對比DS90LV031ATMX)
- Earlier-generation upgrade path (對比DS90LV031BTM)
設計說明
Route each LVDS output as a controlled-impedance differential pair with minimal length and matched spacing. Keep the pair over a continuous reference plane, avoid stubs and test pads that create discontinuities, and separate it from switching-current paths. Differential skew directly degrades receiver eye opening, so verify intra-pair length matching and the impedance of both conductors using the actual PCB stack-up.
Place the DS90LV031ATM close to the interface connector or signal-source component so that the high-speed section of each pair contains no unnecessary trace. Keep the output enable nets away from data pairs unless their timing is deliberately related, and provide a short, quiet ground-return path for the device. Where the connection crosses board regions, use a defined reference-plane transition and stitching vias instead of an abrupt layer change.
Do not treat the receiver, connector, and transmission line as interchangeable elements when creating an LVDS link. Confirm the receiver’s termination scheme, input thresholds, enable polarity, and propagation timing against the DS90LV031A datasheet. Also verify the exact ordering suffix: M, TM, ATMX, BTM, and NOPB designations can describe different package, generation, or lead-free attributes even when the footprint remains identical.
合規資訊
Texas Instruments lists a NOPB lead-free ordering option for the DS90LV031A family. RoHS, REACH, halogen-free, and conflict-minerals statements for the exact ordering code were not established and remain unknown.
