CDCL1810RGZRG4

Overview

The CDCL1810RGZRG4 is a fanout buffer and clock distribution device manufactured by Texas Instruments. It provides a 1:10 output ratio, accepting LVDS differential inputs and generating CML differential outputs. The component supports maximum frequencies up to 650 MHz and operates within a supply voltage range of 1.7 V to 1.9 V. Designed for surface mount applications, it is housed in a 48-VQFN package with an exposed pad (7x7 mm). The device functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• 1:10 Fanout Buffer Configuration
• LVDS Input to CML Output Conversion
• Maximum Frequency of 650 MHz
• 1.7 V to 1.9 V Supply Voltage Range

Applications

• Clock distribution in high-speed digital systems
• Fanout buffering for differential clock signals
• Data communication interface timing circuits

Procurement Notes

Verify the specific ordering suffix RGZRG4 against official Texas Instruments documentation to confirm package type and reel specifications. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to soldering. Confirm availability through authorized distributors as stock levels vary.

Selection Notes

Select this component when a single LVDS source must drive ten CML loads. Verify that the system power supply strictly maintains the 1.7 V to 1.9 V range. Ensure the PCB layout accommodates the 48-VQFN footprint and thermal requirements for the exposed pad.

Part Context

This part belongs to the CDCL series of clock buffers and drivers from Texas Instruments. It is specifically designed for high-frequency clock distribution tasks requiring signal integrity preservation between different logic families.

Replacement Considerations

Consult Texas Instruments selection guides for compatible parts within the CDCL family. Verify pin-to-pin compatibility and electrical parameter alignment before substituting.
