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.  
FEATURES  
Supply voltage: 3.0 to 3.6V  
PLL loop filter built-in
