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 lter 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. FEATURES I I I PLL loop lter built-in Supply voltage: 3.0 to 3.6V I Crystal oscillator circuit built-in Low current consumption: 35mA typ. (VDD = 3.3V, all outputs with no load) I Sampling frequency fs: 44.1/48kHz 27MHz master clock I 16-pin VSOP package (Pb free) (internal PLL reference clock) Generated clocks (Refer to “Output Frequency Listing” on page 18 for details.)
