CDCLVD2108RGZR

Overview

The CDCLVD2108RGZR is a low-jitter, dual 1:8 universal-to-LVDS buffer manufactured by Texas Instruments. It operates within a supply voltage range of 2.375 V to 2.625 V and supports maximum input and output frequencies of 800 MHz. The device accepts LVCMOS, LVDS, or LVPECL inputs and provides LVDS outputs. It is housed in a 48-VQFN package with an exposed pad, designed for surface mount applications across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:8 fanout buffer configuration
• Universal input compatibility (LVCMOS, LVDS, LVPECL)
• Low jitter performance optimized for high-speed data transmission
• Supports up to 800 MHz operation frequency

Applications

• High-speed serial link clock distribution
• Data converter clocking systems
• Telecommunications infrastructure timing
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'RGZR' corresponds to the Tape & Reel packaging format as indicated in the product description. Confirm that the 48-VQFN package dimensions match the design requirements for the target PCB layout. Ensure the voltage supply rails strictly adhere to the 2.375 V to 2.625 V specification to maintain optimal jitter performance and signal integrity.

Selection Notes

Select this component when a dual-channel, 1:8 fanout solution is required for LVDS distribution. It is suitable for designs needing universal input flexibility from LVCMOS, LVDS, or LVPECL sources. Consider the 48-VQFN package size and thermal characteristics during the PCB layout phase to ensure adequate heat dissipation and mechanical stability.

Part Context

This part belongs to the CDCLVD21xx series of low-jitter clock buffers from Texas Instruments. These devices are engineered to provide precise clock distribution in high-speed digital systems. The CDCLVD2108 variant specifically offers two independent 1:8 buffers, making it ideal for complex timing architectures requiring multiple synchronized clock domains.

Replacement Considerations

Check for direct pin-compatible alternatives within the CDCLVD21xx family, such as the CDCLVD2106 or CDCLVD2104, if fewer outputs are sufficient. Verify that any substitute maintains the same 800 MHz frequency capability and LVDS output drive strength.
