CDCLVP2108RGZR

Overview

The CDCLVP2108RGZR is a high-performance clock buffer manufactured by Texas Instruments, designed for signal distribution in high-speed digital systems. It features a single differential input and sixteen LVPECL outputs, providing a 1:16 fanout ratio. The device supports input signals from LVCMOS, LVDS, LVPECL, and LVTTL logic families. It operates with a supply voltage range of 2.375V to 3.6V and functions within an ambient temperature range of -40°C to 85°C. The component is housed in a 48-VQFN package with an exposed pad, suitable for surface mount assembly.

Feature Summary

• Provides 1:16 fanout distribution with one differential input and sixteen LVPECL outputs
• Supports multiple input logic standards including LVCMOS, LVDS, LVPECL, and LVTTL
• Operates on a single supply voltage between 2.375V and 3.6V
• Rated for industrial operating temperatures from -40°C to 85°C

Applications

• High-speed clock distribution networks
• Data converter clocking systems
• Telecommunications infrastructure 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 (7x7) package dimensions match the design footprint requirements. Ensure the LVPECL output voltage levels are compatible with the receiving circuitry inputs before finalizing procurement orders.

Selection Notes

Select this component when a single clock source must drive up to sixteen LVPECL loads simultaneously. Verify that the system power supply can maintain the required 2.375V to 3.6V range under all load conditions. Consider the thermal performance of the 48-VQFN package if the application involves high ambient temperatures or limited airflow.

Part Context

This part belongs to the CDCLVP series of high-performance clock buffers from Texas Instruments. These devices are engineered for low jitter and precise timing applications. The CDCLVP2108 specifically addresses designs requiring significant fanout capabilities while maintaining signal integrity across various logic input types.

Replacement Considerations

Direct replacements within the same family include the CDCLVP2104 (8 outputs) and CDCLVP2106 (12 outputs). For different pin counts or output configurations, consult the manufacturer's cross-reference tools to ensure compatibility with existing board layouts and timing specifications.
