CDCM1802RGTT

Overview

The CDCM1802RGTT is a Texas Instruments clock buffer and driver featuring a single circuit with a 1:2 output ratio. It supports differential input and output configurations, accepting LVCMOS, LVPECL, or LVTTL signals and providing LVCMOS or LVPECL outputs. The device operates at a maximum frequency of 800 MHz with a supply voltage range of 3 V to 3.6 V. Designed for surface mount applications, it is housed in a 16-VQFN package (3x3 mm) with an exposed pad. The component functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports LVCMOS, LVPECL, and LVTTL inputs with LVCMOS or LVPECL outputs
• Maximum operating frequency of 800 MHz
• Single circuit configuration with 1:2 fanout ratio
• Operates on a 3 V to 3.6 V power supply

Applications

• Clock distribution networks requiring low skew buffering
• High-speed digital systems utilizing LVPECL or LVCMOS standards
• Consumer electronics and industrial equipment operating between -40°C and 85°C

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pin compatibility and electrical characteristics. Ensure the selected package variant matches the required PCB footprint for the 16-VQFN (3x3 mm) form factor. Confirm that the supply voltage requirements align with the system design constraints before procurement.

Selection Notes

Select this component when a single-input, dual-output clock buffer is required for frequencies up to 800 MHz. It is suitable for designs needing flexibility in input logic levels (LVCMOS/LVPECL/LVTTL) and output drive capabilities. Consider the 16-VQFN package size for space-constrained surface-mount layouts.

Part Context
