SM8703AV  
Clock Generator for MPEG2 System  
NIPPON PRECISION CIRCUITS INC.  
OVERVIEW  
The SM8703AV is a 27 MHz master clock, 5-system output clock generator for MPEG2 system. It has 2 built-  
in PLLs that, with the addition of a single crystal oscillator element, can generate 384fs, 512fs and 768fs  
clocks which are necessary for MPEG2 system, plus independent fixed-frequency 27 MHz and 33.8688 MHz  
output clocks. Each output can stop unused output by using disable function, therefore, unnecessary radiation  
can be suppressed. Also, visual and audio synchronous is not disrupted since each output frequency is kept in  
the normal ratio. Supported sampling frequencies (fs) include 44.1 or 48 kHz.
