  • Page 76 CIRCUIT OPERATIONAL DESCRIPTION 2) Motor Drive IC: BA5810FP(IA02) BA5810FP(IA02) is 5 channel motor operating IC which has 4-channel BTL driver and 1 channel reversible driver and 2 out of 4 channels are used as Stepping Motor driver. Driver IC generates the focus signal and the tracking signal for pick-up actuator, the sled signal for feed, spindle signal and the load signal for opening and closing of the tray.
  • Page 77 CIRCUIT OPERATIONAL DESCRIPTION MPEG Decoder The signal read from DVD disc is output into the RFsignal and Servo related signal through the RF IC and they are input into the MPEG decoder and processed the MPEG decoding and divided into video/audio signal. The video signal is output into the analog audio signal through the built-in encoder block and also the audio signal into the audio DAC through the audio decoder block.
