CDCLVP1212RHAT

Overview

The CDCLVP1212RHAT is a low additive jitter clock buffer manufactured by Texas Instruments. It features a 2:12 fanout ratio, accepting differential inputs and providing LVPECL outputs. The device supports input signal formats including LVCMOS, LVDS, LVPECL, and LVTTL. It operates at frequencies up to 2 GHz with a supply voltage range of 2.375 V to 3.6 V. Packaged in a 40-VQFN (6x6 mm) exposed pad case, it is designed for surface mount installation. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• 2:12 Fanout Ratio: Distributes two differential input signals to twelve LVPECL output channels.
• Low Additive Jitter: Optimized for high-speed clock distribution applications requiring minimal noise addition.
• Flexible Input Compatibility: Supports LVCMOS, LVDS, LVPECL, and LVTTL input logic levels.
• High-Speed Operation: Capable of processing clock signals with maximum frequencies up to 2 GHz.

Applications

• High-speed data converter clock distribution
• FPGA and ASIC clock tree generation
• Telecommunications infrastructure timing networks

Procurement Notes

Verify the specific ordering suffix RHAT corresponds to the Tape & Reel packaging configuration. Confirm that the 40-VQFN package dimensions match the PCB footprint requirements. Ensure the LVPECL output voltage levels are compatible with downstream receiver inputs without additional level shifting components.

Selection Notes

Select this component when a 2-to-12 fanout is required with LVPECL outputs. Verify that the system power supply can maintain the 2.375 V to 3.6 V range. Check if the -40°C to +85°C industrial temperature range meets environmental constraints. Consider thermal dissipation capabilities of the exposed pad VQFN package under continuous 2 GHz operation.

Part Context

This part belongs to the CDCLVP series of low additive jitter buffers from Texas Instruments. It serves as a distribution element in complex timing architectures, bridging primary clock sources to multiple high-speed endpoints. The RHAT suffix indicates the reel-based packaging format used for automated assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate other members of the CDCLVP family or the LMK1D series for alternative pinouts or feature sets if direct replacement is necessary.
