DS90LV049QMT/NOPB

Overview

The DS90LV049QMT/NOPB is an automotive-grade LVDS interface integrated circuit manufactured by Texas Instruments. It features two drivers and two receivers, supporting data rates up to 400 Mb/s. The device accepts LVCMOS or LVTTL inputs and provides LVDS outputs. It operates on a single 3V to 3.6V power supply with a typical operating current of 35 mA. The component is qualified under AEC-Q100 standards for automotive applications. It functions within a temperature range of -40°C to +125°C and is housed in a 16-pin TSSOP package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Supports high-speed differential signaling at 400 Mb/s
• Compatible with LVCMOS and LVTTL input logic levels

Applications

• Automotive infotainment systems
• In-vehicle display interfaces
• Automotive sensor data transmission

Procurement Notes

Verify the specific suffix 'Q' indicates automotive grade qualification when sourcing. Confirm the package type matches the design requirements. Check RoHS compliance status as indicated in official documentation. Ensure the supplier provides valid traceability for automotive components. Validate that the part number corresponds exactly to the required driver/receiver configuration.

Selection Notes

Select this component for designs requiring certified automotive reliability. Ensure the system voltage remains within the 3V to 3.6V range. Verify that the PCB layout supports the TSSOP-16 footprint. Consider the thermal dissipation capabilities given the operating temperature limits. Confirm compatibility with the target LVDS receiver devices in the signal chain.

Part Context

This part belongs to the DS90LV049 family of low-voltage differential signaling transceivers. The 'Q' suffix distinguishes it from commercial variants by meeting automotive quality requirements. It serves as a bridge between parallel digital buses and serial LVDS links. The device is designed for robust performance in electrically noisy environments typical of vehicle interiors.

Replacement Considerations

The DS90LV049TMT/NOPB is a commercial grade alternative without automotive qualification. The SN65LVDS049 is a compatible functional equivalent from the same manufacturer. Verify pinout and electrical specifications before substituting any variant.
