integrated circuit systems, inc. general description features ics9118-01 ics9118-02 frequency generator for digital video systems ics9118-01/02revb 7/27/99 block diagram 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). 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. ? 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 pin configuration 14-pin soic 2 x , 1 x ) z h m ( s f ] 0 : 2 [ o i d u a 1 0 ) z h m ( o i d u a 2 0 ) z h m ( f e r ) z h m ( t r a u ) z h m ( 0 0 . 7 20 0 0e t a t s i r te t a t s i r te t a t s i r te t a t s i r t 0 0 . 7 21 0 06 9 0 . 44 4 1 . 60 0 . 7 20 2 6 8 . 1 0 0 . 7 20 1 04 4 6 . 52 . 7 6 4 . 80 0 . 7 20 2 6 8 . 1 0 0 . 7 21 1 04 4 1 . 66 1 2 . 90 0 . 7 20 2 6 8 . 1 0 0 . 7 20 0 12 9 1 . 88 8 2 . 2 10 0 . 7 20 2 6 8 . 1 0 0 . 7 21 0 19 8 2 . 1 12 . 4 3 9 . 6 10 0 . 70 2 6 8 . 1 0 0 . 7 20 1 18 8 2 . 2 12 3 4 . 8 10 0 . 7 20 2 6 8 . 1 0 0 . 7 21 1 1w o lw o lw o lw o l functionality vdd=3.0-5.5v, temp=0-70 product preview documents contain information on products in the formative or design phase development. charactersitic data and other specifications are design goals. ics reserves the right to change or discontinue these procucts without notice. obsolete ics9118-02 obsolete
