CDCP1803RGETG4

Overview

The CDCP1803RGETG4 is a Texas Instruments clock buffer and driver featuring a 1:3 fanout ratio. It supports maximum frequencies of 800 MHz for both input and output signals. The device accepts differential inputs in CML, HSTL, LVCMOS, LVDS, LVTTL, SSTL-2, or VML formats and provides three LVPECL outputs. It operates on a single supply voltage ranging from 3V to 3.6V. The component is housed in a 24-VQFN package with an exposed pad, measuring 4x4 mm, and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports 800 MHz operation with low skew distribution
• Accepts multiple input standards including LVDS, LVCMOS, and CML
• Provides three LVPECL outputs for high-speed signaling
• Operates on a 3V to 3.6V single power supply

Applications

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

Procurement Notes

Verify the specific ordering suffix G4 against the manufacturer's current documentation to confirm lead-free status and RoHS compliance details. Ensure the 24-VQFN package dimensions match the target PCB footprint requirements. Confirm moisture sensitivity level handling procedures during assembly to prevent damage.

Selection Notes

Select this component when a 1:3 fanout with LVPECL outputs is required for frequencies up to 800 MHz. Verify that the system power supply remains within the 3V to 3.6V range. Ensure the input source matches one of the supported logic families such as LVDS or LVCMOS. Consider the thermal performance of the exposed pad design for heat dissipation needs.

Part Context

This part belongs to the CDCP1803 series of clock buffers manufactured by Texas Instruments. It is designed for applications requiring reliable clock distribution with minimal jitter. The device integrates buffering and driving capabilities into a compact surface-mount package suitable for dense circuit board layouts.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the CDCP1803RGET. Verify electrical specifications like propagation delay and output drive strength before substituting.
