SM8701BM

SM8701BM NIPPON PRECISION CIRCUITS INC. DVD Player Clock Generator OVERVIEW The SM8701BM is a 27 MHz master clock, 5-system output clock generator for DVD players. It has 2 built-in PLLs that, with the addition of a single crystal oscillator element, can generate 256fs, 384fs and 768fs clocks plus independent fixed-frequency 27 MHz and 33.8688 MHz output clocks. Supported sampling frequencies (fs) include the standard 32, 44.1 or 48 kHz, or double-frequency 64, 88.2 or 96 kHz.
