Detail of Functions

CD DSP functions

<Playback functions>

 Playback mode: CLV playback/Jitter free playback (VCEC)

 Playback speed: Normal speed, double speed

<RF Processing block>

 RF system: AGC, CD-R and CD-R/W playback support, peak hold, bottom hold

 Error system: TE signal generation, FE signal generation

 Detection: Track count signal, Jitter, Defect (black, mirror)

 LASER power controller (APC)

 DC offset voltage cancellation

<Servo control block>

 All servo systems as tracking, focus, sled and spindle are implemented with digital processing.

 Automatic adjustment functions: focus gain, focus bias, focus offset,

tracking gain, tracking offset and tracking balance

 Shock detection / Interruption detection

<CD signal processing block>

 EFM signal synchronization detection, protection and interpolation

 Error detection, correction (C1=double, C2=quadruple/double)

 Jitter margin ±19 frames

<CD TEXT processing block>

 Buffers CD-TEXT data

 Starts buffering desired ID3/ID4 of CD-TEXT data.

<CD-ROM processing block>

 CD-ROM decoding (Mode1, Mode2 <form1, form2>)

 Outputs CD-ROM decoded data
