Product details
Overview
DS90LV031ATMX/NOPB from Texas Instruments is a quad CMOS LVDS differential line driver operating at 3.3 V, delivering >400-Mbps data rates (200 MHz), 0.4-ns max differential skew, 2-ns max propagation delay, and ±350-mV differential output swing. It serves as a low-power, high-speed interface driver in point-to-point digital links between FPGAs, ASICs, and receivers in industrial automation and grid infrastructure systems.
For engineers reviewing the DS90LV031ATMX/NOPB datasheet, DS90LV031ATMX/NOPB pinout, DS90LV031ATMX/NOPB application, or DS90LV031ATMX/NOPB equivalent, key selection criteria include its TRI-STATE® enable control, current-mode LVDS output architecture requiring 100-Ω termination, industrial temperature range (–40°C to +85°C), and compatibility with IEEE 1596.3 and TIA/EIA-644 standards.
Technical Context
The DS90LV031ATMX/NOPB implements a balanced current-source LVDS driver architecture with fixed 3.5-mA nominal output current, generating 350-mV differential voltage across a 100-Ω load. Its outputs are fully differential, with offset voltage centered at 1.25 V and <35 mV change between logic states.
It supports dual-enable logic (EN active-high / EN* active-low) for common TRI-STATE control of all four channels, enabling ultra-low idle power (6 mA typical ICCZ). The device requires resistive termination on all outputs and is incompatible with AC-coupled or unterminated configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 200 MHz / 400 Mbps - supports high-speed serial links without signal integrity degradation |
| Differential skew (max) | 0.4 ns - ensures timing alignment across all four channels for parallel bus transmission |
| Propagation delay (max) | 2 ns - enables sub-5-ns round-trip latency in short-reach point-to-point links |
| Supply voltage | 3.3 V ±10% - compatible with modern low-voltage digital I/O domains (LVTTL/LVCMOS) |
| Differential output voltage | 250–450 mV - meets LVDS standard minimum noise margin (250 mV) with 100-Ω termination |
| Idle supply current | 2.6–6 mA - achieves ultra-low power state when outputs disabled via EN/EN* |
| Operating temperature | –40°C to +85°C - qualified for industrial environments including factory floors and substations |
Pinout & Package
DS90LV031ATMX/NOPB is packaged in a 16-pin TSSOP (PW) with body size 5.00 mm × 4.40 mm, optimized for surface-mount assembly and thermal performance (RθJA = 114°C/W).

| DOUT1−–DOUT4− (Pins 3,5,11,13) | Output | Inverting LVDS output terminals; form differential pairs with corresponding DOUT+ pins |
| EN (Pin 4) | Input | Active-high enable controlling TRI-STATE of all four drivers |
| EN* (Pin 12) | Input | Active-low enable OR-ed with EN for flexible logic-level control |
| VCC (Pin 16) | Power | 3.3-V supply input; requires local 0.1-µF + 0.01-µF decoupling per layout guidelines |
| GND (Pin 8) | Ground | Reference return path for all signals and power; must be low-impedance plane connection |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90LV031AQM/NOPB | Same electrical specs; automotive-grade (–40°C to +125°C), AEC-Q100 qualified | Required for under-hood or rail-side deployments where extended temperature and reliability validation are mandatory | Select when automotive qualification or extended temperature range is required; otherwise DS90LV031ATMX/NOPB suffices for industrial use |
| SN65LVDS31DR | Identical pinout and function; TI second-source part with same SOIC/TSSOP packaging and 3.3-V LVDS drive capability | No functional difference; used interchangeably in legacy designs where SN65LVDS31DR was originally specified | Valid drop-in alternative with identical timing, skew, and power behavior; suitable for BOM rationalization or dual-sourcing |
Compared with DS90LV031AQM/NOPB, the DS90LV031ATMX/NOPB offers lower cost and sufficient performance for non-automotive industrial use; compared with SN65LVDS31DR, it shares identical functionality but reflects TI's consolidated part numbering post-National Semiconductor acquisition.

FAQ
What is the recommended termination for DS90LV031ATMX/NOPB outputs?
The DS90LV031ATMX/NOPB requires a 100-Ω differential termination resistor placed as close as possible to the receiver input. The device is a current-mode driver and will not function correctly without this termination, as the 3.5-mA output current develops the specified 350-mV differential voltage across the resistor. Values between 90 Ω and 110 Ω are acceptable per datasheet specifications.
Does DS90LV031ATMX/NOPB support both 3.3-V and 5-V logic inputs?
Yes, DS90LV031ATMX/NOPB accepts LVTTL and LVCMOS input levels, with VIH = 2 V (min) and VIL = 0.8 V (max) at VCC = 3.3 V. It is interoperable with existing 5-V LVDS systems at the receiver side but does not accept 5-V inputs directly-external level-shifting is required for 5-V logic driving DS90LV031ATMX/NOPB inputs.
Can DS90LV031ATMX/NOPB outputs be left unterminated?
No. DS90LV031ATMX/NOPB is a current-mode LVDS driver that requires a resistive load (90–110 Ω) to convert output current into valid differential voltage. Unterminated or AC-coupled outputs violate the device's operating conditions and result in undefined output states, excessive power dissipation, and potential damage over time.
What is the function of EN and EN* pins on DS90LV031ATMX/NOPB?
The EN (pin 4) and EN* (pin 12) pins provide dual-enable logic for the TRI-STATE function of DS90LV031ATMX/NOPB. Either EN = high or EN* = low disables all four driver outputs simultaneously, placing them in high-impedance state and reducing supply current to 2.6–6 mA. Both enables are OR-ed internally, allowing flexible control from active-high or active-low logic sources.
Is DS90LV031ATMX/NOPB pin-compatible with older 5-V LVDS drivers?
DS90LV031ATMX/NOPB has the same 16-pin TSSOP/SOIC footprint as the 5-V DS90C031 and industry-standard 26LS31 RS-422 drivers, enabling PCB layout reuse. However, it operates at 3.3 V only and is not electrically compatible with 5-V supplies or inputs-direct replacement requires voltage domain adaptation in surrounding circuitry.
