CDCF2510PWRG4

Application Specific Clock/Timing Overview

The CDCF2510PWRG4 is a 3.3-V phase-lock loop (PLL) clock driver manufactured by Texas Instruments, housed in a 24-pin TSSOP package. It operates within a frequency range of 25 MHz to 140 MHz and supports a supply voltage of 3 V to 3.6 V. The device distributes one clock input to ten outputs with low skew and jitter characteristics. Static phase error at 66 MHz to 133 MHz is ±125 ps, while cycle-to-cycle jitter is |70| ps at 66 MHz to 100 MHz and |65| ps at 100 MHz to 133 MHz. It includes integrated series-damping resistors and requires a stabilization time of 1 ms for PLL lock.

Application Specific Clock/Timing Feature Summary

• Distributes one clock input to ten low-skew outputs using an internal PLL

Application Specific Clock/Timing Procurement Notes

Verify that the component matches the exact part number CDCF2510PWRG4, as ordering suffixes may indicate variations in packaging or environmental compliance. Confirm RoHS status and lead finish details against the manufacturer's latest documentation before procurement.

Application Specific Clock/Timing Selection Notes

Ensure the application frequency falls between 25 MHz and 140 MHz. Verify that the system can accommodate the required 1 ms stabilization time for the PLL to achieve phase lock after power-up or signal changes. Check that the load capacitance requirements are met to maintain specified jitter and skew performance.

Application Specific Clock/Timing Part Context

This device belongs to the CDCF2510 family of high-performance, low-skew, low-jitter PLL clock drivers. It is specifically engineered for synchronous DRAM applications where precise phase alignment and minimal jitter are critical for system stability and data integrity.
