CDCM1802RGTR

Overview

The CDCM1802RGTR is a Texas Instruments clock buffer and driver featuring a 1:2 fanout ratio. It supports differential LVCMOS, LVPECL, and LVTTL inputs with corresponding LVCMOS or LVPECL outputs. The device operates at a maximum frequency of 800 MHz within a supply voltage range of 3 V to 3.6 V. Packaged in a 16-VQFN (3x3 mm) exposed pad configuration, it is designed for surface-mount assembly. The component functions as a distribution circuit suitable for high-speed digital systems requiring precise clock signal routing.

Feature Summary

• 1:2 Fanout Ratio: Distributes one input clock signal to two independent output channels.
• Flexible Input/Output: Supports LVCMOS, LVPECL, and LVTTL inputs; provides LVCMOS or LVPECL outputs.
• High Frequency Operation: Capable of handling clock signals up to 800 MHz.
• Compact Packaging: Delivered in a 16-VQFN (3x3 mm) package with an exposed thermal pad.

Applications

• High-speed data acquisition systems
• Telecommunications equipment
• Industrial control networks

Procurement Notes

Verify the specific suffix 'RGTR' corresponds to the Tape & Reel packaging format when sourcing. Confirm that the 16-VQFN footprint matches the design layout requirements. Ensure the operating temperature range of -40°C to 85°C aligns with the target environment specifications.

Selection Notes

Select this component when a single clock source must drive two distinct loads with minimal skew. Verify that the system power supply remains stable between 3 V and 3.6 V. Consider the exposed pad requirement for proper thermal management during PCB layout.

Part Context

This part belongs to the CDCM1802 series of low-power clock buffers. It serves as a distribution element in timing architectures where signal integrity and low jitter are critical. The device replaces discrete logic solutions by integrating buffering capabilities into a compact semiconductor package.

Replacement Considerations

Check pin-to-pin compatibility with other 1:2 LVPECL/LVCMOS buffers from the same manufacturer family before substitution. Verify that alternative components support the required 800 MHz frequency and 3.3 V nominal supply voltage.
