Integrated Circuit Systems, Inc. Obsolete ICS9118-01 ICS9118-02 Frequency Generator for Digital Video Systems General Description The ICS9118-01 and ICS9118-02 are 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. Pin Configuration 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 Functionality VDD=3.0-5.5V, TEMP=0-70° 14-Pin SOIC ICS9118-02 Obsolete Block Diagram 9118-01 9118-02 RevB 7/27/99 X1, X2 (MHz) FS [2:0] 27.00 27.00 27.00 27.00 27.00 27.00 27.00 27.00 000 001 010 011 100 101 110 111 AUDIO 01 (MHz) Tristate 4.096 5.644 6.144 8.192 11.289 12.288 Low AUDIO 02 (MHz) Tristate 6.144 8.467. 2 9.216 12.288 16.934. 2 18.432 Low REF (MHz) UART (MHz) Tristate 27.00 27.00 27.00 27.00 7.00 27.00 Low Tristate 1.8620 1.8620 1.8620 1.8620 1.8620 1.8620 Low PRODUCT PREVIEW documents contain information on products in the formative or design phase development.
