Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix RGET against the manufacturer datasheet to confirm the tape and reel packaging configuration. Ensure the order quantity aligns with the standard factory pack size of 250 units. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to ensure compatibility with assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a fixed 250 MHz output frequency is required without external programming. Compare against the CDC421A100RGET for lower frequency needs or the CDC421A212RGET for alternative frequencies. Verify that the LVPECL output swing matches the receiver input requirements of the target application circuit.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CDC421A series of clock synthesizers designed for low-jitter applications. It serves as a direct replacement for older CDCE421 devices in many designs, offering improved integration by embedding the crystal oscillator. The series is optimized for reducing phase noise in high-speed data transmission environments.
