Integrated Circuit Systems ICS9118-01
The ICS9118-01 and ICS9118-02 are low-cost, highperform-ance clock generators designed to support digital video sys-tems. 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).GENERAL DESCRIPTION
27 MHz VIDEO, 1.8 MHz UART and AUDIO clocks are generated from the recovered 27 MHz signal. 4 t e U .c om Obsolete ICS9118-01 ICS9118-02 w w w .D a S a tFEATURES

● 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 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. Pin Configuration
