CDCLVD1204RGTT

Overview

The CDCLVD1204RGTT is a high-performance, low-jitter, low-skew 2:4 differential clock buffer manufactured by Texas Instruments. It supports multiple input signal types including LVCMOS, LVDS, and LVPECL, with LVDS outputs. The device operates at a maximum frequency of 800 MHz with a maximum propagation delay of 600 ps. It functions within a supply voltage range of 2.375 V to 2.625 V and an operating temperature range of -40°C to +85°C. Packaged in a 16-VQFN (3x3 mm) exposed pad format, it is designed for timing-critical applications requiring precise clock distribution.

Feature Summary

• 2:4 differential fanout buffer supporting LVCMOS, LVDS, and LVPECL inputs with LVDS outputs
• Maximum operating frequency of 800 MHz with 600 ps maximum propagation delay
• Low jitter and low skew performance suitable for high-speed data converters and communications
• Operates on a single 2.5 V supply (2.375 V to 2.625 V)

Applications

• High-speed data converters
• Communications equipment
• Test and measurement instruments

Procurement Notes

Verify the package type matches the 16-VQFN (3x3 mm) specification. Confirm the supply voltage requirements align with the 2.375 V to 2.625 V range. Ensure the operating temperature range of -40°C to +85°C meets system environmental constraints. Check that the LVDS output configuration is compatible with downstream loads.

Selection Notes

Select this component when a 2:4 differential clock distribution solution is required with LVDS outputs. It is appropriate for systems needing low jitter performance at frequencies up to 800 MHz. Consider the 16-VQFN package for space-constrained surface-mount designs. Ensure input signals are compatible with LVCMOS, LVDS, or LVPECL standards.

Part Context

This part belongs to the CDCLVD series of clock buffers from Texas Instruments. It is specifically designed as a fanout buffer to distribute clock signals to multiple destinations while maintaining signal integrity. The RGTT suffix indicates the specific tape and reel packaging variant.

Replacement Considerations

Check for direct pin-to-pin replacements within the CDCLVD family or other TI clock buffers with similar 2:4 ratios and LVDS outputs. Verify electrical parameters such as max frequency, propagation delay, and supply voltage compatibility before substitution.
