Block Diagram
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.
• Generates 27 MHz VIDEO, 1.8 MHz UAR T 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
