DS90LV049HMTX

Overview

The DS90LV049HMTX is a high-speed LVDS transceiver manufactured by Texas Instruments, housed in a 16-pin TSSOP surface-mount package. It integrates two independent drivers and two receivers, 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 logic inputs. Key electrical parameters include a propagation delay of 3.5 ns, a differential input high threshold of 35 mV, and a low threshold of -100 mV. It functions reliably within an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Supports full-duplex data transmission with integrated dual drivers and dual receivers for simultaneous bidirectional signaling.
• Accepts standard LVTTL or LVCMOS logic levels directly without requiring external translation circuitry.
• Provides robust signal integrity through low-voltage differential signaling (LVDS) output standards.

Applications

• High-speed serial data links in industrial control systems
• Point-to-point communication interfaces in embedded computing platforms
• Display interface connections requiring reliable differential signaling

Procurement Notes

Verify the specific suffix against the datasheet to confirm package type and temperature rating. Ensure the ordering code matches the required tape-and-reel quantity if automated assembly is planned. Confirm RoHS compliance status for environmental regulations. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Validate that the voltage supply aligns with the 3V to 3.6V operational range.

Selection Notes

Select this component when dual-channel LVDS connectivity is required alongside direct TTL/CMOS interfacing. Consider the 400 Mbps speed limit and 125°C thermal capability for harsh environments. Evaluate the 16-TSSOP footprint against available PCB space constraints. Compare against similar TI devices if higher channel counts or different input/output voltage levels are needed.

Part Context

This device belongs to the DS90LV049 family of LVDS interface controllers designed for high-speed digital transmission. It serves as a bridge between parallel logic buses and serial differential lines. The HMTX suffix indicates a specific high-temperature variant in the TSSOP package. It complements other members of the series offering varying driver/receiver configurations.

Replacement Considerations

Direct substitutes include the DS90LV049HMT/NOPB for tube packaging or the DS90LV049TMT/NOPB for alternative reel options. Verify pin compatibility and electrical specifications before swapping. Check for updated revision levels in the new part number to ensure functional equivalence.
