Texas Instruments DS90LV028ATMX/NOPB

Overview

DS90LV028ATMX/NOPB from Texas Instruments (formerly National Semiconductor) is a dual 3.3V LVDS differential line receiver designed for high-speed point-to-point data links. It supports >400 Mbps data rates, delivers 2.5 ns max propagation delay and 50 ps typical differential skew, and operates across −40°C to +85°C. It translates low-voltage (350 mV typical) differential inputs into 3V CMOS logic outputs in industrial imaging and FPGA interconnect applications.

For engineers reviewing the DS90LV028ATMX/NOPB datasheet, DS90LV028ATMX/NOPB pinout, DS90LV028ATMX/NOPB application, or DS90LV028ATMX/NOPB equivalent, key selection criteria include fail-safe input behavior, flow-through SOIC-8 pinout, 3.3V supply compatibility, and ANSI/TIA/EIA-644 compliance for robust noise immunity in high-density PCB layouts.

Technical Context

The DS90LV028ATMX/NOPB implements a dual-channel LVDS receiver with independent input comparators and CMOS output drivers. Each channel features internal fail-safe biasing that forces HIGH output under open, shorted, or 100Ω-terminated input conditions, and supports ±1V common-mode range centered at +1.2V.

It uses a flow-through pinout (RIN+, RIN−, GND, VCC, ROUT, ROUT) to minimize trace crossing and signal integrity degradation. Propagation delay variation is tightly controlled: ≤2.5 ns max, ≤0.1 ns typical channel-to-channel skew, and ≤50 ps differential pulse skew - enabling precise timing alignment in parallel data buses.

Key Specifications

Pinout & Package

DS90LV028ATMX/NOPB is supplied in an 8-pin SOIC package (JEDEC MO-08A, 150-mil width), optimized for manual soldering and automated reflow. The flow-through layout minimizes PCB routing complexity and crosstalk.

FAQ

What is the operating voltage range for DS90LV028ATMX/NOPB?

The DS90LV028ATMX/NOPB operates from +3.0 V to +3.6 V, with typical performance specified at +3.3 V. Its absolute maximum supply voltage is +4.0 V, and it draws only 9 mA typical supply current at 3.3 V. This narrow 3.3V-centric range ensures compatibility with modern FPGA I/O banks and avoids level-shifter overhead in mixed-voltage systems.

Does DS90LV028ATMX/NOPB support fail-safe operation with open inputs?

Yes, DS90LV028ATMX/NOPB guarantees a HIGH output state when either input channel is left open, shorted, or terminated with 100 Ω. This is achieved via internal high-value pull-up/pull-down resistors - no external components are required. This behavior is explicitly verified across the full −40°C to +85°C temperature range and is critical for hot-plug and cable-disconnect resilience.

What package type is used for DS90LV028ATMX/NOPB?

DS90LV028ATMX/NOPB uses an 8-pin SOIC package (JEDEC MO-08A, 150-mil width), designated as "TMS" in TI's ordering nomenclature. It is not the LLP variant (DS90LV028ATLD); the "TMX/NOPB" suffix confirms the green, lead-free SOIC-8 package with standard gull-wing leads suitable for both reflow and wave soldering.

How does DS90LV028ATMX/NOPB handle common-mode voltage variations?

DS90LV028ATMX/NOPB accepts a common-mode input range of 0 V to +2.4 V, centered nominally at +1.2 V, with full functionality maintained across −40°C to +85°C. Its differential threshold remains stable at ±100 mV regardless of common-mode shift, enabling reliable operation despite ground potential differences up to 1 V between transmitter and receiver.

Is DS90LV028ATMX/NOPB compliant with industry LVDS standards?

Yes, DS90LV028ATMX/NOPB conforms fully to ANSI/TIA/EIA-644 LVDS standard. It interoperates with all compliant LVDS drivers including TI's DS90LV011A and Maxim's MAX9110, supporting 350 mV typical differential input swing, 100 Ω termination, and 1.2 V common-mode bias - ensuring plug-and-play compatibility in multi-vendor systems.
