1 / 12 page SM8707E/F Clock Generator with Dual PLLs SEIKO NPC CORPORATION - 1 OVERVIEW The 8707E/F 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 (VDD=3.3V, all outputs with no load) ■ Sampling frequency fs: 44.1/48kHz ■ 27MHz master clock ■ 16-pin VSOP package (Pb free) (internal PLL reference clock) ■ Generated clocks SM8707E SM8707F Video system output 27.0000MHz 27.0000MHz Audio system output 512fs 768fs Signal processor system output 33.8688MHz 16.9344MHz 33.8688MHz ■ Low jitter output (1-sigma output load capacitance typical values) SM8707E SM8707F Video system output 20ps 20ps Audio and Signal processor system output 55ps 40ps APPLICATIONS PACKAGE DIMENSIONS ■ DVD players/recorders (Unit : mm) ■ DVD car navigation system Weight: 0.07g ORDERING INFOMATION Device Package SM8707EV SM8707FV 16pin VSOP |
