SM8706A

Clock Generator for DVD Players

OVERVIEW

The SM8706A is a clock generator IC that generates 3 clocks with 6 outputs from a 36.8640MHz master clock

for application in DVD players. The SM8706A has 2 built-in PLL circuits that together with a crystal oscillator

can generate the 384fs and 768fs audio system clocks, 27MHz and 54MHz video system clocks, and

16.9344MHz and 33.8688MHz signal processor system clocks required for a DVD player. The SM8706A also

supports the 44.1kHz and 48kHz sampling frequencies, and the sampling frequency can be switched while the

device is operating.
