CDCLVD2108RGZT

Overview

The CDCLVD2108RGZT is a low jitter, dual 1:8 universal-to-LVDS clock buffer manufactured by Texas Instruments. It operates on a single 2.5 V supply with a voltage range of 2.375 V to 2.625 V. The device accepts LVCMOS, LVDS, or LVPECL inputs and provides eight LVDS outputs per section, supporting maximum frequencies up to 800 MHz. It is housed in a 48-VQFN (7x7 mm) package with an exposed pad for surface mount installation. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:8 fanout buffer architecture providing 16 total LVDS outputs
• Universal input compatibility supporting LVCMOS, LVDS, and LVPECL logic levels
• Maximum output frequency capability of 800 MHz
• Operates on a single 2.5 V power supply

Applications

• High-speed clock distribution networks
• Data converter timing interfaces
• FPGA clock routing systems

Procurement Notes

Verify the specific ordering suffix RGZT corresponds to the Tape & Reel packaging configuration. Confirm that the 48-VQFN package dimensions match the required PCB footprint. Ensure the 2.5 V supply voltage aligns with the system design specifications before procurement.

Selection Notes

Select this component when a dual-section buffer is required to drive multiple LVDS loads from various input standards. The 800 MHz frequency limit suits high-speed digital applications. Verify that the 48-pin VQFN package is compatible with the assembly process and thermal management requirements.

Part Context

This part belongs to the CDCLVD21xx series of low jitter clock buffers. It serves as a signal conditioning and distribution element within complex timing architectures, converting diverse input signals into standardized LVDS outputs for reliable high-speed transmission.

Replacement Considerations

Check for pin-compatible alternatives within the same Texas Instruments family that offer similar input/output configurations and frequency ratings.
