Servo signal processor for CD

BU9312AKS

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 miniatur-

ized, low-power-consumption applications.

FApplications

Portable CD players, portable stereos and mini compo-

nent stereo systems

FFeatures

1) InternalPLL circuit, allowing EFM data demodulation

and bit clock sampling with minimum attached com-

ponents.

7) Internal track jump sequencer that jumps the de-

sired number of tracks.

8) Single-chip IC with deinterleaving function and in-

ternal C1 / C2 double error detection, correction

and flag processor.

2) Frame synch signal detection and protection.

3) Internal focus, tracking and thread servo filters.

Characteristics can be controlled with commands

from the controller.

9) Signals to DAC are output via MSB fast 2’SCOMP

serial outputs, enabling control of ON / OFF opera-

tion of CD-ROM interpolators.

4) Subcode serial output pin.

5) Output pins for P code and Q code.

6) Internal CLV sequencer that automatically sets the

CLV mode.

10) 16k bits of internal SRAM, for the storage of up to

± 4 frames of jitters.

11) Doubled-speed playback.
