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

^ꢀLow current consumption: 35mA typ.

^ꢀCrystal oscillator circuit built-in

^ꢀSampling frequency fs: 44.1/48kHz

^ꢀ16-pin VSOP package (Pb free)

(V = 3.3V, all outputs with no load)

^ꢀ27MHz master clock

(internal PLL reference clock)

^ꢀGenerated clocks (Refer to “Output Frequency Listing” on page 18 for details.)
