2 / 27 page LC78616PE www.onsemi.com 2 Detail of Functions [CD-DSP functions] < Playback functions> Playback mode : CLV playback / Jitter free playback (VCEC) Playback speed : Normal speed, double speed, quadruple speed (CLV playback / Jitter free playback) <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 decoded data to the buffer memory. Starts buffering of CD-TEXT decoded data from desired ID3/ID4. <Shock proof processing block> Shock proof processing using with external 16M-bit or 64M-bit Memory Approximately 10sec. with 16Mbit or 40sec. with 64Mbit [CD data processing functions] <CDDA data processing block> Interpolation Mute function ( 12 dB, ∞) Digital attenuator De-emphasis filter <CDROM data processing block> CLV playback : Fixed normal speed or double speed Jitter free playback (VCEC) : Free speed within quadruple speed *CDROM Data is not buffering to SDRAM and output directly <Outputs format> Digital 3 lines output(LRCK,BCK,DATA) Supports various external audio data output format IIS (48 fs), MSB First, Right-Justified, Left-Justified (32 fs / 48 fs), 16-bit data length Slave mode Output DATA synchronized to external Clock input (LRCK and BCK) Digital output (S/PDIF, only CLV playback mode) [Internal Microcontroller functions] <Sequencer control> CD playback control Servo control, CD-TEXT processing, Digital data output control, etc. <Communication control between main controller> The SIO interface using CE, CL, DI, DO and BUSYB pins is available as communication format. External main controller can control this IC directly such as “stop oscillation” or “restart oscillation” or so on at the internal register open mode (REG_READY high condition). Even while the oscillation is stopped, some of general port can be controlled by host controller. <Peripheral interface block> GPIO port 8 ports maximum (Shared with other functions.) <Program memory block> Mask-ROM type ROM Correct function is built in for the partial change of the program and Host controller can use this. <Others> Watch Dog Timer Notifies to outside from a pin or resets internally. Power management (Two kinds of sleep mode) (1) Only the clock for CPU core is operating and clocks for other blocks are stopping. (2) All clocks are stopping. [Others] <Internal power supply> 1.5 V regulator for internal blocks |
