PCK857 - 66-150MHz Phase Locked Loop Differential 1:10 SDRAM Clock Driver

Datasheet Summary

Description

Zero delay buffer to distribute an SSTL differential clock input pair to 10 SSTL_2 differential output pairs.

Outputs are slope controlled.

External feedback pin for synchronization of the outputs to the input.

Features

  • Optimized for clock distribution in DDR (Double Data Rate) SDRAM.
