DS90LV049HMTX/NOPB

Overview

The DS90LV049HMTX/NOPB is a high-performance dual LVDS transceiver manufactured by Texas Instruments. It integrates two independent drivers and two receivers within a single 16-pin TSSOP package, supporting full-duplex communication at data rates up to 400 Mbps. The device operates on a single 3V to 3.6V power supply and accepts LVTTL or LVCMOS inputs while generating compliant LVDS outputs. Key electrical parameters include a propagation delay of 3.5 ns, a differential input threshold range from -100 mV to 35 mV, and a maximum power dissipation of 866 mW. It functions reliably across an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Supports high-speed data transmission up to 400 Mbps with low skew for signal integrity
• Features internal fault-safe biasing on receiver inputs to ensure known output states during signal loss
• Provides electrostatic discharge (ESD) protection exceeding 10 kV on both driver outputs and receiver inputs

Applications

• High-speed serial data links in desktop computers and servers
• Point-to-point interconnects in wireless base stations
• Display interface circuits requiring LVDS compliance

Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the component meets RoHS3 standards if environmental compliance is mandatory for the target assembly process. Cross-reference the 16-TSSOP footprint dimensions with PCB layout guidelines to prevent soldering defects.

Selection Notes

Select this component when a dual-channel LVDS solution is required for point-to-point connections. It is suitable for designs needing compatibility with ANSI/TIA/EIA-644-A standards. Consider the 3.3V operating voltage and the availability of the TSSOP package for surface-mount applications. Verify that the 400 Mbps speed meets the system bandwidth requirements without necessitating higher-speed alternatives.

Part Context

This part belongs to the DS90LV049 family of LVDS interface integrated circuits. It is functionally compatible with the SN65LVDS049 series, allowing for potential design swaps between these specific TI models. The 'H' designation typically indicates an extended temperature range variant compared to standard commercial grade parts, ensuring reliability in harsher environments.

Replacement Considerations

The SN65LVDS049 is a documented functional equivalent within the Texas Instruments portfolio. Both devices share similar dual-driver/receiver architectures and LVDS compliance. Verify pin-to-pin compatibility and thermal performance before substituting.
