95VLP857AGLF

Application Specific Clock/Timing Overview

The ICS95VLP857AGLF is a 2.5V low-power wide-range frequency clock driver manufactured by Integrated Circuit Systems, Inc., now part of Renesas Electronics. It operates within a frequency range of 45MHz to 233MHz and features a 48-pin TSSOP package with a 0.50mm pitch. The device provides 1-to-10 differential clock distribution using SSTL_2 levels, incorporating feedback pins for input-to-output synchronization. Key electrical specifications include cycle-to-cycle jitter under 50ps, output-to-output skew below 40ps, and period jitter of ±30ps. It supports Spread Spectrum Clocking inputs and includes an automatic power-down feature when the input signal is removed.
