LC78615E CMOS LSI www.onsemi.com Compact Disc Player IC Overview The LC78615E integrates RF signal processor for CD-DA/R/RW, servo control, EFM signal processing and playback controller (Sequencer : 8-bit CPU). It is possible to make CD player system using with micro controller and driver ICs with less components. PQFP64 14x14 / QIP64E Function RF signal processing for CD-DA/R/RW, servo control and EFM signal processing. Outputs CDDA, CDROM data Outputs CD-TEXT decoded data using the serial interface or Serial communication line with external main controller. CD playback system is realized with simple macro commands by the external controller because of the internal Sequencer (8-bit CPU). Operating Voltage : 3.3V Typical Operating Temperature : 40 C to +85C Package : QIP64E(14 14) ORDERING INFORMATION See detailed ordering and shipping information on page 24 of this data sheet. Semiconductor Components Industries, LLC, 2015 1 Publication Order Number : January 2015 - Rev. 1 LC78615E/D LC78615E 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. CD data processing functions <CDDA data processing block> Interpolation Mute function(12dB, ) 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 <Outputs format > Digital 3 lines output (LRCK, BCK, DATA) Supports various external audio data output format IIS (48fs), MSB First, Right-Justified, Left-Justified (32fs/48fs), 16 bit data length Slave mode Output DATA synchronized to external Clock input (LRCK/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 clock is stopped, some of general port can be controlled by host controller. <Peripheral interface block> GPIO port 15 ports maximum(Shared with other functionslerate.) <Program memory block> Mask-ROM type ROM Collect 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> 1.5V regulator for internal blocks www.onsemi.com 2
