ICS9120-56
Frequency Timing Generator for EtherNet & Hard Drives
General Description
The
ICS9120-56
is a high performance frequency generator
designed to support hard disk drive and EtherNet systems. It
offers all clock frequencies required for the servo and decoder
sections of these devices. These frequencies are synthesized
from a single 25.00 MHz on-chip oscillator.
High accuracy, low jitter PLLs meet the 100 ppm frequency
tolerance required by these systems. Fast output clock
edge rates minimize board induced jitter.
