CDC2510BPWR

Overview

The CDC2510BPWR is a 3.3-V phase-lock loop (PLL) clock driver designed for synchronous DRAM applications. It distributes one clock input to ten outputs with low skew and jitter. Operating frequencies range from 25 MHz to 125 MHz, with a supply voltage of 3 V to 3.6 V. The device features integrated series damping resistors and requires no external RC network. It operates within a temperature range of 0°C to 70°C in a 24-pin TSSOP package.

Feature Summary

• Distributes one clock input to ten outputs using a PLL for precise frequency and phase alignment
• Includes on-chip series damping resistors to eliminate the need for external RC networks
• Provides separate output enable control for the entire output bank

Applications

• PC SDRAM registered DIMM specifications
• Spread spectrum clock compatible systems
• Synchronous DRAM clock distribution

Procurement Notes

Verify the specific ordering suffix 'B' against the manufacturer's current documentation to confirm availability and exact electrical tolerances. Confirm that the 24-TSSOP package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a single reference clock must be distributed to multiple synchronous memory banks with minimal skew. Ensure the application supports the required stabilization time for the internal PLL to achieve phase lock after power-up or signal changes.

Part Context

This part belongs to the Texas Instruments CDC2510 family of PLL clock drivers. The 'B' suffix typically denotes a specific revision or performance grade within the product line, while 'PWR' indicates the plastic small-outline package type with tape-and-reel packaging.

Replacement Considerations

Check for CDC2510CPWR or CDC2510PWG4 as potential alternatives. Verify pin compatibility and operating temperature ranges before substitution.
