DS90LV049HMT/NOPB

Overview

The DS90LV049HMT/NOPB is a high-speed LVDS interface integrated circuit manufactured by Texas Instruments. It features two drivers and two receivers, supporting data rates up to 400 Mbps. The device operates on a single 3V to 3.6V power supply and utilizes LVTTL or LVCMOS input logic with LVDS differential outputs. Packaged in a 16-pin TSSOP surface-mount format, it supports an extended industrial temperature range from -40°C to +125°C. Key electrical parameters include a propagation delay of 3.5 ns, a maximum power dissipation of 866 mW, and a differential input voltage threshold ranging from -100 mV to 35 mV.

Feature Summary

• Supports full-duplex communication via integrated dual drivers and dual receivers for simultaneous bidirectional data transfer.
• Provides robust signal integrity through low-voltage differential signaling (LVDS) technology, ensuring reliable transmission over long distances.
• Features compatibility with standard LVTTL and LVCMOS logic levels, facilitating direct interfacing with common digital components without additional level shifting.

Applications

• Digital omnidirectional microphone array cascading systems requiring synchronized clock distribution.
• Industrial control systems utilizing legacy LVDS interfaces for reliable data transmission.
• Embedded processing units connecting audio A/D converters to FPGA controllers.

Procurement Notes

Verify the specific suffix 'HMT' against the manufacturer's current datasheet to confirm package dimensions and thermal characteristics. Ensure the component meets RoHS3 compliance requirements if applicable to your manufacturing standards. Cross-reference the ordering part number with authorized distributors to avoid obsolete variants. Confirm that the 16-TSSOP footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring moderate-speed differential signaling with integrated receiver capabilities. It is suitable for applications needing extended temperature operation up to 125°C. Consider alternative devices if higher data rates exceeding 400 Mbps are required or if single-ended output formats are preferred. Evaluate board space constraints as the TSSOP-16 package offers a compact solution compared to larger SOIC packages.

Part Context

This device belongs to the DS90LV049 series of LVDS interface ICs. It serves as a complete transceiver solution, combining transmission and reception functions in a single package. The series is designed for applications demanding noise immunity and low electromagnetic interference. It complements other interface solutions by providing a cost-effective method for connecting digital sources to displays or processors.

Replacement Considerations

The DS90LV049TMT/NOPB is a verified substitute offering identical functional specifications and pinout compatibility. Both variants support the same 400 Mbps data rate and operate within the same voltage and temperature ranges. Verify that the replacement maintains the required 16-TSSOP package configuration for seamless integration into existing designs.
