CDCM1804RTHT

Overview

The CDCM1804RTHT is a fanout buffer and clock distribution device manufactured by Texas Instruments. It operates with a single circuit providing a 1:4 output ratio, supporting maximum frequencies up to 800 MHz. The component accepts differential inputs including CML, HSTL, LVDS, LVPECL, LVTTL, SSTL-2, and VML, while delivering LVCMOS or LVPECL outputs. It functions within a supply voltage range of 3V to 3.6V and is rated for an operating temperature between -40°C and 85°C. The device is housed in a 24-VFQFN exposed pad package.

Feature Summary

• Supports high-speed clock distribution with a maximum frequency of 800 MHz
• Accepts multiple input standards including CML, LVDS, LVPECL, and LVTTL
• Provides flexible output configurations via LVCMOS or LVPECL signals
• Operates on a single 3V to 3.6V power supply

Applications

• High-speed digital signal processing systems
• Telecommunications infrastructure equipment
• Data acquisition and measurement instruments

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and reel specifications. Ensure compatibility with the required input voltage levels and thermal management requirements for the target application environment before procurement.

Selection Notes

Select this component when a low-skew 1:4 clock distribution solution is required for high-frequency applications. Confirm that the system design supports the specified 3V to 3.6V supply range and that the 24-VQFN package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the Texas Instruments clock buffer and driver category. It serves as a fanout buffer, divider, and multiplexer within the broader family of timing components designed for precise clock signal management in complex electronic systems.

Replacement Considerations

Consult official cross-reference data for compatible alternatives. Verify pin-to-pin compatibility and electrical parameter alignment if substituting with other 1:4 LVPECL/LVCMOS clock buffers from different manufacturers.
