CDCP1803RGET

Overview

The CDCP1803RGET is a Texas Instruments clock buffer and driver featuring a 1:3 fanout ratio. It accepts differential inputs from CML, HSTL, LVCMOS, LVDS, LVTTL, SSTL-2, or VML sources and provides three LVPECL outputs. The device supports maximum input and output frequencies of 800 MHz with a maximum propagation delay of 600 ps. It operates on a single 3V to 3.6V supply voltage within an industrial temperature range of -40°C to +85°C. The component is housed in a 24-VQFN (4x4 mm) package with an exposed pad for thermal management.

Feature Summary

• Supports multiple input standards including CML, LVDS, LVCMOS, LVTTL, HSTL, SSTL-2, and VML
• Generates three LVPECL outputs for low-skew clock distribution
• Operates at frequencies up to 800 MHz with 600 ps maximum propagation delay
• Housed in a compact 24-VQFN (4x4 mm) surface-mount package

Applications

• High-speed digital signal processing systems
• FPGA and ASIC clock distribution networks
• Telecommunications infrastructure equipment
• Test and measurement instrumentation requiring precise timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm RoHS compliance and lead time specifications. Ensure that the selected packaging format, such as Tape & Reel or Cut Tape, aligns with the assembly requirements of the target manufacturing process.

Selection Notes

Select this component when a single differential source must drive three LVPECL loads simultaneously. Confirm that the system power supply remains strictly between 3V and 3.6V. Verify that the PCB layout accommodates the 24-VQFN footprint and properly connects the exposed pad for optimal thermal dissipation during operation.

Part Context

This part belongs to the CDCP1803 series of clock buffers manufactured by Texas Instruments. The series focuses on high-frequency signal integrity and flexible input compatibility. The RGET designation identifies the specific commercial grade variant packaged in a 24-pin VQFN form factor suitable for space-constrained electronic designs.

Replacement Considerations

Consult the Texas Instruments product selection guide for alternative devices within the CDCP family that offer compatible pinouts or adjusted frequency capabilities. Cross-reference datasheets to ensure equivalent electrical parameters before substituting.
