CDCP1803RGER

Overview

The CDCP1803RGER is a single-circuit clock buffer manufactured by Texas Instruments, designed for high-speed signal distribution. It operates with a 1:3 input-to-output ratio and supports a maximum frequency of 800 MHz. The device accepts differential inputs in CML, HSTL, LVCMOS, LVDS, LVTTL, SSTL-2, or VML formats and provides three LVPECL outputs. Powered by a 3V to 3.6V supply, it functions within an operating temperature range of -40°C to +85°C. The component is housed in a 24-VQFN package with an exposed pad, suitable for surface mount applications.

Feature Summary

• Supports multiple input standards including CML, LVDS, LVCMOS, and LVTTL
• Provides three LVPECL outputs for fanout buffering
• Maximum operating frequency of 800 MHz
• Operates on a single 3V to 3.6V power supply

Applications

• High-speed data communication systems requiring clock distribution
• Fanout buffering for LVPECL loads
• Signal conditioning for mixed-signal interfaces

Procurement Notes

Verify the specific ordering suffix 'GER' against the manufacturer's official documentation to confirm packaging details such as tape and reel specifications. Ensure that the 24-VQFN footprint matches the target PCB design requirements. Confirm RoHS compliance status through the latest datasheet before finalizing procurement plans.

Selection Notes

Select this component when a 1:3 fanout buffer is required for LVPECL signals. It is appropriate for designs needing compatibility with various input logic levels like LVDS or CML. Verify that the 800 MHz frequency limit meets system timing requirements and that the 3V to 3.6V supply voltage aligns with the available power rails.

Part Context

This part belongs to the Texas Instruments clock buffer family, specifically engineered for distribution and multiplexing tasks. It serves as a solution for converting diverse input standards into low-skew LVPECL outputs. The device is intended for use in electronic circuits where precise clock signal integrity and distribution are critical.

Replacement Considerations

Consult the manufacturer's cross-reference tools for verified alternative part numbers. Ensure any substitute maintains the same 1:3 ratio, LVPECL output type, and 24-VQFN package dimensions for direct compatibility.
