CDC2509BPW

Overview

The CDC2509BPW is a 3.3-V phase-lock loop (PLL) based clock driver manufactured by Texas Instruments. It features one differential input and nine true outputs, with zero inverted outputs. The device is housed in a PDSO24 package. As a PLL-based clock driver, it is designed to generate and distribute clock signals within digital systems. The component operates at a supply voltage of 3.3 V and is intended for applications requiring precise clock distribution.

Feature Summary

• Integrates a phase-locked loop circuit for clock signal generation and stabilization
• Provides nine true output channels for clock distribution
• Supports differential input configuration for noise immunity

Applications

• Clock distribution in high-speed digital systems
• Memory subsystem clocking
• Data communication equipment timing

Procurement Notes

Verify the manufacturer date code and lot number against the original design specifications. Ensure the PDSO24 package dimensions match the PCB footprint requirements. Confirm that the 3.3-V supply voltage aligns with the system power architecture before procurement.

Selection Notes

Select this component when a single differential input must be expanded into nine true outputs using PLL technology. Compare pin compatibility and electrical characteristics with similar parts like the CDC2509BPWR if reel packaging is preferred over tube packaging for assembly processes.

Part Context

This part belongs to the CDC2509 series of 3.3-V PLL clock drivers from Texas Instruments. It shares functional similarities with the CDCF2509 but differs in specific interface configurations. The BPW suffix indicates the specific package type and temperature range suitable for general commercial applications.

Replacement Considerations

The CDC2509BPWR is a direct replacement offering the same functionality in a tape-and-reel format. Other variants such as the CDC2509C or CDC2510B may serve as alternatives depending on specific speed or package requirements.
