CDCP1803RTHR

Overview

The CDCP1803RTHR is a 1:3 LVPECL clock buffer manufactured by Texas Instruments. It operates with a supply voltage range of 3V to 3.6V and supports a maximum frequency of 800 MHz. The device accepts differential inputs including CML, HSTL, LVCMOS, LVDS, LVTTL, SSTL-2, and VML, converting them to three LVPECL outputs. It is housed in a 24-VQFN (4x4) package with an exposed pad and is rated for operation between -40°C and +85°C.

Feature Summary

• 1:3 Fanout Buffer with LVPECL outputs
• Supports multiple input standards: CML, HSTL, LVCMOS, LVDS, LVTTL, SSTL-2, VML
• Maximum operating frequency of 800 MHz
• 24-VQFN (4x4) surface-mount package

Applications

• Clock distribution networks requiring LVPECL signaling
• High-speed digital systems utilizing mixed input logic levels
• Data acquisition and communication equipment

Procurement Notes

Verify the specific ordering suffix 'RTHR' against official Texas Instruments documentation to confirm tape and reel packaging details and any distinct manufacturing lot codes. Ensure compatibility with existing PCB footprints for the 24-VQFN package before procurement.

Selection Notes

Select this component when a single differential or single-ended source must drive three LVPECL loads. Confirm that the system power supply remains within the 3V to 3.6V range. Verify that the required input signal standard (e.g., LVDS, CML) is supported by the device's input circuitry.

Part Context

This part belongs to the CDCP1803 series of clock buffers. It serves as a fanout buffer designed to distribute clock signals from various input standards to LVPECL destinations, commonly used in high-performance computing and telecommunications infrastructure.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as other CDCP1803 variants with different suffixes, ensuring identical electrical characteristics and package dimensions.
