CDCM1804RGER

Overview

The CDCM1804RGER is a fanout buffer and distribution circuit manufactured by Texas Instruments. It provides a 1:4 output ratio with differential input and output capabilities, supporting frequencies up to 800 MHz. The device accepts CML, HSTL, LVDS, LVPECL, LVTTL, SSTL-2, and VML inputs, while delivering LVCMOS or LVPECL outputs. 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-VFQFN package with an exposed pad, designed for surface mount applications.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details such as tape and reel specifications. Ensure that the selected variant matches the required voltage and temperature ratings for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a 1:4 fanout buffer is required for signals up to 800 MHz. Confirm compatibility between the source signal standard (e.g., LVDS, LVPECL) and the supported input list. Verify that the system power supply falls within the 3V to 3.6V range and that the 24-VQFN package fits the PCB layout constraints.

Part Context

This part belongs to the CDCM1804 series of clock buffers and drivers from Texas Instruments. These devices are engineered for low-jitter clock distribution in high-speed digital systems. The RGER suffix indicates a specific manufacturing and packaging configuration within the broader product family.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the 800 MHz frequency limit, 1:4 ratio, and compatible input/output voltage levels.
