ICS9120-49
Frequency Generator for CD-ROM Systems
General Description
The
ICS9120-49
is a high performance frequency generator
designed to support digital compact disk drive systems. It
offers all clock frequencies required for the servo and decoder
sections of these devices. These frequencies are synthesized
from a single 16.9344 MHz on-chip oscillator.
High accuracy, low jitter PLLs meet the 150 ppm frequency
tolerance required by these systems. Fast output clock edge
rates minimize board induced jitter.
Unlike competitive devices, the
ICS9120-49
operates over
the entire 3.0-5.5V range.
