CDCF2510PWG4

Application Specific Clock/Timing Overview

The CDCF2510PWG4 is a 3.3-V phase-lock loop (PLL) clock driver manufactured by Texas Instruments, housed in a 24-pin TSSOP package. It distributes one clock input to a bank of ten outputs with low skew and low jitter characteristics. The device operates at frequencies between 25 MHz and 140 MHz and includes integrated series-damping resistors for point-to-point loads. It requires no external RC network due to an on-chip loop filter. The G input enables or disables all outputs, while the FBIN terminal synchronizes outputs to the clock input.

Application Specific Clock/Timing Feature Summary

• Integrates a PLL to align feedback output to the clock input signal without requiring external RC networks
• Distributes one clock input to a bank of ten low-skew, low-jitter outputs with integrated 25-Ω series-damping resistors
• Features an Output Enable pin (G) to enable or disable all ten outputs simultaneously
• Designed to meet PC133 SDRAM Registered DIMM Specification Rev. 0.9

Application Specific Clock/Timing Applications

• Synchronous DRAM applications
• PC133 SDRAM Registered DIMMs
• Spread Spectrum Clock compatible systems

Application Specific Clock/Timing Procurement Notes

Verify that the component matches the LIFEBUY status indicated in the packaging information addendum. Confirm the specific ordering suffix corresponds to the desired package type and environmental compliance before procurement. Ensure design compatibility with the specified operating temperature range of 0°C to 85°C.

Application Specific Clock/Timing Selection Notes

Select this device when a 3.3-V PLL clock driver is required for synchronous DRAM buses. Ensure the application frequency falls within the 25 MHz to 140 MHz range. Verify that the PCB layout accommodates the 24-pin TSSOP package and allows for proper connection of the FBOUT to FBIN feedback loop.

Application Specific Clock/Timing Part Context

The CDCF2510PWG4 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. The 'G4' suffix indicates RoHS-compliant manufacturing.
