General Description

The ICS9120-46 is a high performance frequency generator designed to support the clock requirements of communication and audio interfaces. It offers the clock frequencies required by 28.8 baud modem plus sound system. These frequencies are synthesized from 14.7456 MHz reference oscillator whose buffered output is available for the reference.

Features

• Generates 49.92 MHz, 40.32 MHz and 14.7456 MHz

• Single 14.7456 MHz crystal reference

• 49.92 MHz accuracy tracks 40.32 MHz reference

• 80ps one sigma jitter maintains 16-bit performance

• Output rise/fall times less than 1.5ns

• On-chip loop filter components

• 3.0-5.5V supply range

• 8-pin, 150-mil SOIC package

Applications

• Specifically designed to support the high performance requirements of communication and audio interfaces.
