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.
The SM8707 series are dual‑PLL clock generator ICs that use a 27 MHz master clock to generate independent audio, video and signal‑processor clock outputs. They are intended for DVD player/recorder designs and support selectable 44.1 kHz or 48 kHz audio sampling frequencies without output spikes.
Key features include a built‑in PLL loop filter and crystal oscillator, low current consumption (35 mA typ.), a 3.0 V–3.6 V supply range, and a 16‑pin VSOP (Pb‑free) package. Detailed pinout, electrical characteristics, and output frequency tables are provided for each device variant (D, E, F, G, H, K, L).
| Supply voltage range | 3.0 V – 3.6 V |
|---|---|
| Current consumption | 35 mA typ. |

The devices operate from a 3.0 V to 3.6 V supply.
Both 44.1 kHz and 48 kHz sampling rates are supported and can be switched via a control pin.
All variants use a 27 MHz master clock.
They are offered in a 16‑pin VSOP (Pb‑free) package.
