SM8707 series
Clock Generator with Dual PLLs
OVERVIEW
The SM8707 series are dual-PLL clock generator ICs, using a 27MHz master clock, that generate independent
audio clock, video clock, and signal processor clock outputs needed in DVD player/recorder applications. Each
PLL loop filter and crystal oscillator circuit are built-in and require no external components, resulting in high-
precision clocks. The lineup includes devices that support both 44.1/48kHz audio sampling frequencies (fs),
switchable using a control pin. The sampling frequency can be switched during operation without generating
any output spike noise.
