Frequency Generator for Multimedia Audio Synthesis

General Description

The ICS9120-08 and ICS 9120-09 are high performance

frequency generators designed to support stereo audio codec

systems. It offers both clock frequencies required by stereo

codecs such as the CS4231 and the AD1848 plus the clock

needed for the OPL4 FM synthesizer. These frequencies can

be synthesized from the existing 14.318 MHz system clock or

from the on-chip oscillator using a 14.318 MHz crystal (-08

only).

High accuracy, low jitter PLLs meet the 0.125% frequency

tolerance and -96dB signal-to-noise ratios required by 16 bit

audio systems. Fast output clock edge rates minimize board

induced jitter.

Unlike competitive devices, the ICS9120-08 and

ICS9120-09 operate over the entire 3.0-5.5V range, with the

-09 providing power-down to minimize energy consumption.
