DS90LV049TMT

Overview

The Texas Instruments DS90LV049TMT is a low-voltage differential signaling (LVDS) interface integrated circuit designed for high-speed data transmission. It integrates two drivers and two receivers within a single package, supporting data rates up to 400 Mbps. The device accepts LVTTL or LVCMOS inputs and converts them to LVDS outputs, while simultaneously receiving LVDS signals and converting them back to LVTTL/LVCMOS levels. It operates on a single 3.0 V to 3.6 V power supply with a typical operating current of 35 mA. The component features a propagation delay of 3.5 ns and is housed in a 16-pin TSSOP surface-mount package. It supports an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates dual LVDS drivers and receivers for simultaneous bidirectional communication
• Converts between single-ended LVTTL/LVCMOS logic levels and differential LVDS signals
• Provides ESD protection capabilities for enhanced signal integrity

Applications

• High-speed serial data links requiring LVDS compatibility
• Industrial control systems operating in extended temperature environments
• Test and measurement equipment interfaces

Procurement Notes

Verify the specific suffix against official documentation, as variations such as TMTX denote reel packaging while TMT indicates tube packaging. Confirm RoHS compliance status through the manufacturer's datasheet rather than distributor summaries. Ensure the selected variant matches the required thermal performance and pinout configuration for the target application design.

Selection Notes

Select this component when a combined transmitter and receiver solution is required for LVDS applications. Verify that the system voltage aligns with the 3.0 V to 3.6 V operating range. Consider the TSSOP-16 footprint constraints during PCB layout. Evaluate the 400 Mbps speed limit against the actual data throughput requirements to ensure adequate performance margins.

Part Context

This part belongs to the DS90LV049 series of LVDS interface ICs manufactured by Texas Instruments. The series provides solutions for converting between standard logic levels and differential signaling standards. The TMT suffix specifically identifies the tube packaging option for this component variant.

Replacement Considerations

The DS90LV049HMTX/NOPB serves as a verified alternative within the same family, offering identical electrical functionality but with an extended maximum operating temperature of 125°C compared to the standard 85°C rating.
