CDCLVP1216RGZR

Overview

The CDCLVP1216RGZR is a high-performance clock buffer and multiplexer manufactured by Texas Instruments. It features a 2:16 ratio, accepting two differential inputs (LVCMOS, LVDS, LVPECL, LVTTL) and providing sixteen LVPECL outputs. The device supports maximum frequencies up to 2 GHz with a supply voltage range of 2.375V to 3.6V. Housed in a 48-VQFN package measuring 7x7 mm, it operates within an industrial temperature range of -40°C to 85°C. This component is designed for precise clock distribution in high-speed digital systems.

Feature Summary

• 2:16 Multiplexing Ratio: Selects between two input sources to drive 16 LVPECL outputs
• High Frequency Operation: Supports clock signals up to 2 GHz
• Universal Input Compatibility: Accepts LVCMOS, LVDS, LVPECL, and LVTTL input protocols
• Compact Packaging: Available in a 48-pin VQFN (7x7 mm) surface-mount package

Applications

• High-speed data communication equipment
• Test and measurement instrumentation
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix RGZR corresponds to the Tape & Reel packaging configuration as indicated in the product parameters. Confirm that the 48-VQFN exposed pad thermal requirements match the target PCB layout design. Ensure the LVPECL output voltage levels are compatible with downstream receiver inputs operating within the specified 2.375V to 3.6V supply range.

Selection Notes

Select this component when a low-skew distribution of a single clock source to sixteen points is required. The 2:16 architecture allows redundancy or selection between two primary clock sources. Verify that the system power supply can maintain stability within the 2.375V to 3.6V window to ensure optimal jitter performance and signal integrity across the full industrial temperature range.

Part Context

This part belongs to the CDCLVP series of high-performance clock buffers from Texas Instruments. It serves as a fanout buffer and multiplexer, distinct from standard dividers or synthesizers. The RGZR suffix denotes the reel packaging format, facilitating automated assembly processes in high-volume manufacturing environments.

Replacement Considerations

Direct replacements within the same family include CDCLVP1212 (12 outputs) or CDCLVP1204 (4 outputs) if fewer channels are sufficient. Cross-family alternatives may require verification of pin compatibility and LVPECL output swing characteristics.
