DS90LV804TSQ

Overview

The DS90LV804TSQ is a four-channel LVDS buffer and repeater manufactured by Texas Instruments. It supports data rates up to 800 Mbps with a propagation delay of 3.2 ns. The device operates on a single 3.3 V supply, drawing 140 mA, within a voltage range of 3.15 V to 3.45 V. Input types include CML, LVDS, and LVPECL, while the output provides LVDS signals. It functions in an industrial temperature range from -40°C to +85°C and is housed in a 32-pin WQFN package.

Feature Summary

• Provides signal buffering and repeating for low-voltage differential signaling applications
• Accepts multiple input standards including CML, LVDS, and LVPECL
• Delivers standardized LVDS outputs for high-speed digital transmission

Applications

• High-speed serial data communication links
• Display interface signal conditioning
• Industrial control system interconnects

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Ensure the component matches the required RoHS compliance status for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the 32-pin WQFN footprint aligns with your PCB design constraints before ordering.

Selection Notes

Select this component when interfacing between different logic families such as CML or LVPECL sources and LVDS destinations. The 800 Mbps speed capability suits moderate-to-high bandwidth requirements. Consider the 3.3 V operating voltage and 140 mA current draw for power budget calculations. The wide input compatibility simplifies design integration across mixed-signal environments.

Part Context

This device belongs to the DS90LV804 series of LVDS interface integrated circuits. It serves as a bridge for signal integrity in high-speed digital systems. The TSQ variant indicates a specific thermal and packaging configuration within the Texas Instruments portfolio. It complements other LVDS drivers and receivers in complex interface architectures.

Replacement Considerations

The DS90LV804TSQX/NOPB is a verified substitute offering identical electrical characteristics and functionality. Both parts share the same 4-channel 800 Mbps LVDS buffer/repeater specification. Verify pinout compatibility and package dimensions during replacement to ensure seamless integration.
