SM8707EV Datasheet Clock Generator

Manufacturer: Nippon Precision Circuits Inc

Overview: 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 ponents, 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.
