The ICS9118-01 a nd ICS9118-02 a re low-cost, highperform-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). The audio clock is synthesized from 27 MHz using a high accuracy, low jitter PLL to meet the synchronization and -96dB signal-to-noise ratios required by 16-bit DSP systems. Fast output clock edge rates minimize board-induced jitter.
