CDCLVD1204RGTR

Overview

The CDCLVD1204RGTR is a low-skew, low-jitter differential clock buffer manufactured by Texas Instruments. It features a 2:4 fanout ratio with differential inputs and outputs. The device supports LVCMOS, LVDS, and LVPECL input signal types while providing LVDS outputs. It operates at a maximum frequency of 800 MHz with a supply voltage range of 2.375 V to 2.625 V. Designed for surface mount assembly, it is housed in a 16-VQFN package (3x3 mm) with an exposed pad. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• 2:4 differential fanout buffer supporting LVCMOS, LVDS, and LVPECL inputs
• LVDS output configuration for high-speed signal distribution
• Maximum operating frequency of 800 MHz
• Low skew and low jitter performance characteristics

Applications

• High-speed communication equipment requiring precise clock distribution
• Network routers and switches
• Test and measurement instruments

Procurement Notes

Verify the specific ordering suffix RGTR corresponds to the Tape & Reel packaging format. Confirm that the 16-VQFN (3x3 mm) package dimensions match the design footprint requirements. Ensure the supply voltage constraints of 2.375 V to 2.625 V are compatible with the target system power rails before procurement.

Selection Notes

Select this component when a 2:4 differential clock distribution solution is required with LVDS outputs. It is suitable for applications needing support for multiple input logic families including LVCMOS, LVDS, and LVPECL. The 800 MHz frequency limit and 16-VQFN package size should align with the board space and speed requirements of the design.

Part Context

This part belongs to the CDCLVD series of clock buffers from Texas Instruments. It is specifically designed as a fanout buffer or multiplexer type device. The RGTR suffix indicates the reel packaging variant of the CDCLVD1204 family member.

Replacement Considerations

Check for pin-compatible alternatives within the CDCLVD series that offer similar 2:4 ratios and LVDS outputs. Verify if other packages such as VQFN-16 variants are available if different mounting preferences exist.
