CDCLVD2104RHDT

Overview

The CDCLVD2104RHDT is a dual 1:4 universal-to-LVDS buffer manufactured by Texas Instruments. It accepts differential inputs in LVCMOS, LVDS, or LVPECL formats and converts them to eight differential LVDS outputs. The device supports a maximum frequency of 800 MHz with a supply voltage range of 2.375 V to 2.625 V. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 28-VQFN package measuring 5x5 mm.

Feature Summary

• Dual 1:4 buffering architecture supporting two independent clock inputs
• Universal input compatibility with LVCMOS, LVDS, and LVPECL standards
• Eight differential LVDS outputs optimized for low skew distribution
• Maximum operating frequency of 800 MHz

Applications

• Clock distribution networks requiring LVDS signaling
• High-speed data acquisition systems
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix RHDT against official datasheets to confirm tape and reel packaging configuration. Ensure the 2.375 V to 2.625 V supply voltage requirement aligns with system power rails. Confirm the 28-VQFN exposed pad thermal requirements for the target PCB layout.

Selection Notes

Select this component when LVDS output is required from mixed-mode inputs like LVCMOS or LVPECL. The 800 MHz limit distinguishes it from higher-frequency variants such as the CDCLVP2104. Verify that the 2.375 V minimum supply voltage is compatible with the design's core voltage levels.

Part Context

This part belongs to the CDC family of clock buffers. It serves as a signal converter and driver, specifically designed to interface between different logic families while maintaining signal integrity over long traces using LVDS technology.

Replacement Considerations

Check for pin-compatible alternatives within the same family. Verify if higher frequency parts like the CDCLVP2104 are suitable if performance margins allow.
