CDCLVD2104RHDR

Overview

The CDCLVD2104RHDR is a Texas Instruments clock buffer and driver featuring one differential input and four LVDS outputs. It operates within a supply voltage range of 2.375 V to 2.625 V and supports maximum frequencies up to 800 MHz. The device accepts LVCMOS, LVDS, or LVPECL inputs and provides LVDS outputs. It is housed in a 28-VQFN package with an exposed pad, measuring 5x5 mm. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Four-channel LVDS fanout buffer with 1:4 distribution ratio
• Supports LVCMOS, LVDS, and LVPECL input signal types
• Maximum operating frequency of 800 MHz
• Operates on a single 2.375 V to 2.625 V power supply

Applications

• High-speed data transmission systems requiring clock distribution
• Telecommunications infrastructure equipment
• Industrial control systems utilizing LVDS signaling

Procurement Notes

Verify the specific ordering suffix RHDR corresponds to the Tape & Reel packaging configuration. Confirm that the 28-VQFN (5x5) package dimensions align with the target PCB footprint requirements. Ensure the 2.375 V to 2.625 V supply voltage range matches the system power design specifications before procurement.

Selection Notes

Select this component when a low-jitter LVDS fanout solution is required for signals up to 800 MHz. It is suitable for designs needing compatibility with multiple input standards including LVCMOS, LVDS, and LVPECL. The 28-pin VQFN package offers a compact surface-mount option for space-constrained applications operating between -40°C and +85°C.

Part Context

This part belongs to the CDCLVD series of clock buffers and drivers from Texas Instruments. These devices are designed for high-performance clock distribution in digital systems. The CDCLVD2104 specifically provides four output channels, distinguishing it from other variants in the family that may offer different output counts or input/output configurations.

Replacement Considerations

Check datasheets for other CDCLVD21xx series parts to verify pin compatibility and electrical parameters. Ensure any substitute maintains the 28-VQFN package and 800 MHz frequency capability.
