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 highprecision 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.
