CDC2509CPW

Overview

The CDC2509CPW is a 1-to-9 PLL-based clock driver manufactured by Texas Instruments. It features nine true outputs and zero inverted outputs, housed in a 24-pin PDSO (TSSOP) package. The device operates within a supply voltage range of 3.0 V to 3.6 V. It supports a maximum operating temperature of +85°C and a minimum of 0°C. The component is part of the CDC2509C series and utilizes a phase-locked loop for clock distribution.

Feature Summary

• Integrates a phase-locked loop for stable clock generation
• Provides nine true output channels for signal distribution
• Designed for low-noise clock buffering applications

Applications

• Memory subsystem clock distribution
• DRAM DIMM timing synchronization
• High-speed digital system clocking

Procurement Notes

Verify the specific suffix 'CW' against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure compatibility with the required 3.0 V to 3.6 V supply rails. Confirm that the 24-TSSOP package meets the thermal and spatial constraints of the target design before finalizing procurement.

Selection Notes

Select this component when a single input clock requires expansion into nine distinct output paths with minimal skew. Verify that the system power supply aligns with the 3.3 V nominal requirement. Consider the TSSOP-24 footprint during PCB layout to ensure adequate spacing for high-frequency signals.

Part Context

This device belongs to the Texas Instruments CDC2509 family of clock drivers. It serves as a buffer and distributor for clock signals in complex digital systems. The CPWR variant shares similar functionality but differs in packaging format. This specific model provides a surface-mount solution for space-constrained designs.

Replacement Considerations

The CDC2509CPWRG4 is a documented equivalent offering identical electrical specifications in a different package configuration. Verify pin compatibility if substituting directly on existing footprints.
