General Description

The ICS9118-01 and ICS9118-02 are low-cost, high-perform-ance clock generators designed to support digital video sys-tems. 27 MHz VIDEO, 1.8 MHz UART and AUDIO clocks are generated from the recovered 27 MHz signal. The on-chip crystal oscillator can be used in conjunction with an exter-nal D/A conversation circuit to provide ±130 ppm clock recovery using a standard 27 MHz crystal (contact ICS for application details).

Features

• Generates 27 MHz VIDEO, 1.8 MHz UART and synchronous AUDIO codec clocks

• Selectable AUDIO clock supports 256x and 384x over-sampling of 16.00, 22.05, 24.00, 32.00, 44.10 and 48.00 kHz

• On-chip crystal oscillator enables 27 MHz clock recovery

• 80ps one sigma jitter maintains 16-bit performance

• 3.0V - 5.5V supply range

• 14-pin, 150-mil SOIC package

Applications

• Specifically designed to support the high performance clocking requirements of digital video set-top and multi-media systems
