ICS9120M-09中文资料ICST数据手册PDF规格书

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).

Features

• Generates 16.934 MHz and 24.576 MHz stereo codec clocks plus the 33.868 MHz OPL4 clock

• Single 14.318MHz crystal or system clock reference

• Buffered REFCLK output

• 0.125 frequency accuracy meets OPL4 specifications

• 100 ps one sigma jitter maintains 16 bit performance

• Output rise/fall times less than 2.0 nS

• On chip loop filter components

• 3.3V - 5 V supply range

• 8 pin, 150mil SOIC package

Applications

• Specifically designed to support the high performance requirements of multimedia audio systems.
