CDCLVP1204RGTT

Overview

The CDCLVP1204RGTT is a Texas Instruments clock buffer and multiplexer featuring a 2:4 input-to-output ratio. It supports LVCMOS, LVDS, LVPECL, and LVTTL inputs with LVPECL outputs. The device operates at frequencies up to 2 GHz with a maximum propagation delay of 450 ps. It functions within a supply voltage range of 2.375 V to 3.6 V and an operating temperature range of -40°C to +85°C. The component is housed in a 16-VQFN package with an exposed pad, designed for surface mount applications.

Feature Summary

• Supports multiple input types including LVCMOS, LVDS, LVPECL, and LVTTL
• Maximum output frequency of 2 GHz with LVPECL outputs
• Low propagation delay of 450 ps maximum
• Integrated multiplexer functionality for signal selection

Applications

• High-speed communication equipment requiring precise timing
• Network routers and switches
• Test and measurement devices

Procurement Notes

Verify the specific suffix RGTT corresponds to the 16-VQFN (3x3) package and Tape & Reel or Cut Tape packaging options. Confirm that the 2.375V to 3.6V supply voltage range aligns with the target system design requirements before procurement.

Selection Notes

Select this component when a differential 2:4 fanout buffer with low jitter is required for high-frequency signals up to 2 GHz. Ensure the application supports LVPECL outputs and can accommodate the specified 16-VQFN footprint with thermal considerations for the exposed pad.

Part Context

This part belongs to the CDCLVP1204 series of clock buffers from Texas Instruments. It is designed for applications demanding low added jitter and skew, making it suitable for distributing clock signals in complex digital systems where timing integrity is critical.

Replacement Considerations

Check for pin-compatible alternatives within the same family, such as other variants in the CDCLVP1204 series, ensuring they match the 2:4 ratio and LVPECL output configuration.
