CDC318DLR

Overview

The CDC318DLR is a low skew clock driver manufactured by Texas Instruments. It functions as a one-line to eighteen-line clock distribution component, designed to fan out a single input clock signal into multiple outputs with minimal timing variation. The device incorporates an I2C control interface for configuration management. This architecture supports high-speed digital systems requiring precise clock synchronization across numerous endpoints.

Feature Summary

• One-to-eighteen line clock distribution capability
• Low skew output characteristics for timing precision
• Integrated I2C control interface for configuration

Applications

• High-speed digital system clock distribution
• Multi-component synchronization networks
• Embedded systems requiring precise timing alignment

Procurement Notes

Verify the specific package type and operating temperature range against the official datasheet before procurement. Confirm that the I2C address settings align with the target system design requirements. Ensure compatibility with the host controller's I2C bus voltage levels.

Selection Notes

Select this component when a single clock source must drive up to eighteen loads with strict skew limitations. Verify that the system requires I2C programmability for dynamic clock routing or power management. Compare against fixed-function clock buffers if configuration flexibility is not required.

Part Context

This part belongs to the CDC318 family of clock drivers from Texas Instruments. It is functionally related to variants such as the CDC318A and CDC318ADL, which share the same core clock distribution functionality but may differ in package options or revision status.

Replacement Considerations

Direct replacements include CDC318A and CDC318ADL. Verify pinout compatibility and I2C register mapping before substitution. Ensure the alternative package meets the mechanical constraints of the existing PCB layout.
