DS90LV049TMTX

Overview

The DS90LV049TMTX is a low-voltage differential signaling (LVDS) transceiver manufactured by Texas Instruments. It integrates two drivers and two receivers within a single package, supporting data transmission rates up to 400 Mbps. The device accepts LVTTL or LVCMOS inputs and converts them to LVDS outputs for high-speed communication. It operates on a supply voltage ranging from 3 V to 3.6 V, with a typical operating current of 35 mA. The component features a propagation delay of 3.5 ns and includes electrostatic discharge (ESD) protection. It is housed in a 16-pin TSSOP surface-mount package and supports an extended industrial temperature range.

Feature Summary

• Integrates dual LVDS drivers and receivers for full-duplex communication
• Converts single-ended LVTTL/LVCMOS signals to differential LVDS outputs
• Includes built-in ESD protection for enhanced signal integrity
• Supports high-speed data transfer at rates up to 400 Mbps

Applications

• High-speed serial data links in industrial equipment
• Flat panel display interfaces requiring LVDS conversion
• Medical imaging systems needing reliable signal transmission
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature rating. Ensure the ordering part number matches the required tape-and-reel or cut-tape configuration for your assembly process. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance status and any recent product change notices affecting this specific variant.

Selection Notes

Select this component when designing circuits that require interface between standard logic levels and LVDS networks. Verify that the system power supply remains within the 3 V to 3.6 V range to ensure proper operation. Confirm that the PCB layout accommodates the 16-pin TSSOP footprint and maintains impedance control for the differential pairs to minimize signal reflection at 400 Mbps.

Part Context

This device belongs to the DS90LV049 family of LVDS interface integrated circuits. The family provides solutions for converting parallel or single-ended signals into differential formats for long-distance, noise-immune transmission. Variants within the series may differ in package options, temperature ranges, or specific electrical characteristics, necessitating careful selection based on application requirements.

Replacement Considerations

Check for direct pin-compatible alternatives such as the DS90LV049HMTX/NOPB, which offers an extended temperature range up to 125°C. Verify functional equivalence regarding data rate and input/output compatibility before substitution. Consult the manufacturer's obsolescence notices to ensure long-term availability of the selected replacement.
