CDCLVP1216RGZT

Overview

The CDCLVP1216RGZT is a high-performance clock buffer and multiplexer manufactured by Texas Instruments. It features a 2:16 fanout ratio, accepting two differential inputs (LVCMOS, LVDS, LVPECL, or LVTTL) and routing one to sixteen LVPECL outputs. The device supports maximum frequencies up to 2 GHz with a supply voltage range of 2.375V to 3.6V. It operates within an industrial temperature range of -40°C to +85°C and is housed in a compact 48-VQFN package measuring 7x7 mm.

Feature Summary

• 2:16 Multiplexing: Selects between two input sources for distribution to 16 LVPECL outputs
• High Frequency Support: Operates at clock frequencies up to 2 GHz
• Universal Input Compatibility: Accepts LVCMOS, LVDS, LVPECL, and LVTTL signals
• Compact Packaging: Available in a 48-pin VQFN (7mm x 7mm) surface-mount package

Applications

• High-speed data communication systems
• Telecommunications infrastructure equipment
• Test and measurement instrumentation
• Industrial control systems requiring precise clock distribution

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel quantity. Confirm that the 48-VQFN package dimensions align with PCB footprint requirements. Ensure the 2.375V to 3.6V supply voltage range is compatible with the system power architecture before finalizing procurement orders.

Selection Notes

Select this component when a 2:16 fanout with low skew is required for LVPECL loads. Verify input signal compatibility with LVCMOS, LVDS, LVPECL, or LVTTL standards. Consider the 48-VQFN thermal performance if operating near the upper temperature limit of 85°C. Compare against lower-frequency variants if 2 GHz capability exceeds design needs.

Part Context

This part belongs to the CDCLVP series of high-performance clock buffers designed for demanding timing applications. It serves as a critical component in systems requiring robust clock distribution from multiple sources to numerous downstream devices while maintaining signal integrity at high speeds.

Replacement Considerations

Check for direct pin-compatible alternatives within the CDCLVP family. Verify that substitute parts support the same 2:16 ratio and LVPECL output configuration. Ensure replacement components meet the 2 GHz frequency specification and 48-VQFN package constraints.
