  • Page 124 http://www.xiaoyu163.com 1. CIRCUIT DESCRIPTIONS 3 7 63 1515 0 UPD63763CGJ, multifunctional LSI used in this device, has built-in CD-ROM decoder and MP3/WMA decoder, as shown in Fig.1.0.1, as well as the conventional CD block, allowing to play CD-ROMs, in which MP3/WMA files are recorded, while the recent mainstay of the CD LSI is the LSI integrating the core DSP with DAC or RF amplifier, which are generally used as peripheral circuits.
  • Page 125 http://www.xiaoyu163.com 1.1 PREAMPLIFIER BLOCK (UPD63763CGJ: IC201) 3 7 63 1515 0 In the preamplifier block, the pickup output signals are processed to generate signals that are used in the subsequent blocks: servo, demodulator, and control blocks. Signals from the pickup are I/V converted in the pickup with the preamplifier with built-in photo detectors, and after added with the RF amplifier, they are used to produce such signals as RF, FE, TE, and TE zero-cross signals.
  • Page 126 http://www.xiaoyu163.com 1.1.2 RF and RFAGC amplifiers 3 7 63 1515 0 The output from the photo-detector (A + C) and (B + D) is provided from the RFO terminal as the RF signal (which can be used for eye-pattern check), after it is added, amplified, and equalized inside this LSI. The low frequency component of the voltage RFO is calculated as below.
  • Page 127 http://www.xiaoyu163.com 1.1.3 Focus error amplifier 3 7 63 1515 0 The photo-detector outputs (A + C) and (B + D) are passed through the differential amplifier and the error amplifier, and (A + C - B - D) is provided from the pin 136 as the FE signal. The low frequency component of the voltage FE is calculated as below.
  • Page 128 http://www.xiaoyu163.com 1.1.6 Tracking zero-cross amplifier 3 7 63 1515 0 The tracking zero-cross signal (hereinafter referred to as TEC signal) is obtained by amplifying the TE signal by fourfold, and used to detect the tracking-error zero-cross point. As the purpose of detecting the zero-cross point, the following two points can be named: 1.
  • Page 129 http://www.xiaoyu163.com 1.2 SERVO BLOCK (UPD63763CGJ: IC201) 3 7 63 1515 0 The servo block performs servo control such as error signal equalizing, in-focus, track jump and carriage move. The DSP block is the signal-processing unit, where data decoding, error correction, and compensation are performed. The FE and TE signals, generated in the preamplifier stage, are A/D-converted, and output drive signals for the focus, tracking, and carriage systems via the servo block.
