Manufacturer
Integrated Device Technology, Inc.
Datasheet
Low-Cost 8-Pin Frequency Generator
General Description
Block Diagram
The ICS9120-45 is a high performance frequency generator
designed to support the clock requirements of communication
and audio interfaces.
High accuracy, low-jitter PLLs meet the -96dB signal-to-
noise ratios required by 16-bit audio systems. Fast output
clock edge rates minimize board induced jitter.
The on-chip XTAL oscillator accuracy is better than ±100ppm
for an AT cut, 18pF load crystal with initial accuracy of ppm
plus TC, aging and load variation of ±20ppm each assuming
33pF ±5% external load capacitors.
