CDC2509CPWR

Overview

The CDC2509CPWR is a 1-to-9 PLL clock driver manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 3.6V and supports a maximum output frequency of 140MHz. The device is housed in a 24-TSSOP package with a width of 4.40mm. It functions as a single circuit clock buffer or driver, utilizing LVCMOS output types. The component is designed for surface mount installation and complies with RoHS3 specifications.

Feature Summary

• Integrates a phase-locked loop (PLL) for clock signal generation and distribution
• Provides one input to nine outputs configuration for clock fan-out applications
• Supports LVCMOS output logic levels for digital system compatibility

Applications

• DRAM DIMM clock buffering
• Memory subsystem clock distribution
• Digital signal processing clock networks

Procurement Notes

Verify the specific suffix 'G4' if environmental compliance documentation is required, as it denotes lead-free status. Confirm the package type matches the design footprint. Ensure the operating temperature range aligns with the target application environment. Check for obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single differential or single-ended clock source needs to drive up to nine loads. Verify that the required output frequency does not exceed 140MHz. Ensure the system power supply remains stable between 3V and 3.6V. Consider the 24-TSSOP package constraints during PCB layout planning.

Part Context

This part belongs to the CDC2509 series of clock drivers. It shares functional similarities with the CDCF2509 but differs in specific internal architecture and intended memory interface optimization. The CPWR suffix indicates the commercial temperature grade and TSSOP packaging format used by Texas Instruments.

Replacement Considerations

The CDC2509CPWRG4 is a verified equivalent variant offering identical electrical performance with confirmed lead-free manufacturing compliance. Other members of the CDC2509 family may serve as alternatives if pinout and electrical parameters are compatible.
