BU9312AKS General Description
The BU9312AKS is a CD servo signal processing IC that contains a speed doubling unadjusted PLL, program servo,
and signal processor, and that delivers low voltage operation and low power consumption. This IC is ideal for miniaturized, low-power-consumption applications.
BU9312AKS Features
` Internal PLL circuit, allowing EFM data demodulation and bit clock sampling with minimum attached components.
` Frame synch signal detection and protection.
` Internal focus, tracking and thread servo filters. Characteristics can be controlled with commands from the controller.
` Subcode serial output pin.
` Output pins for P code and Q code.
` Internal CLV sequencer that automatically sets the CLV mode.
` Internal track jump sequencer that jumps the desired number of tracks.
` Single-chip IC with deinterleaving function and internal C1 / C2 double error detection, correction and flag processor.
` Signals to DAC are output via MSB fast 2'SCOMP serial outputs, enabling control of ON / OFF operation of CD-ROM interpolators.
` 16k bits of internal SRAM, for the storage of up to ± 4 frames of jitters.
` Doubled-speed playback.
