  • Page 97 1. CIRCUIT DESCRIPTIONS The recent mainstay of the CD LSI is the LSI integrating the core DSP with DAC or RF amplifier, which are generally employed as peripheral circuits, however, PE5611B, used in this product, is an LSI integrating the afore-mentioned LSI unit and microcomputer unit in one chip, with an additional USB host control section.
  • Page 98 1.1 PREAMPLIFIER BLOCK 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 99 1.1.2 RF and RFAGC amplifiers 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 100 1.1.3 Focus error amplifier 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 135 as the FE signal. The low frequency component of the voltage FE is calculated as below.
  • Page 101 1.1.6 Tracking zero-cross amplifier 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 102 1.2 SERVO BLOCK (PE5611B: IC201) 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.
  • Page 103 Search start Output from FD terminal The broken line in the figure is assumed in the A blind period case without focus servo. FE controlling signals You can ignore this for blind periods. FSS bit of SRVSTS1 resistor RFOK signals The status of focus close is judged from the statuses of FSS and RFOK after about 10 mS.
  • Page 104 (a) The track jump operation is automatically performed by the auto-sequence function inside the LSI with a command from the CPU of the LSI. For the track jumps used in the search mode, a single track jump and four to 100 multi-track jump are available in this system.

  • Page 106 1.2.3 Carriage servo system The carriage servo system inputs the output of the low frequency component from the tracking equalizer (information on the lens position) to the carriage equalizer, and, after the gain is increased to a certain level, outputs the drive signal from the CD of the LSI.
  • Page 107 1.2.4 Spindle servo system In the spindle servo system, the following modes are available: 1) Kick Used to accelerate the disc rotation in the setup mode. 2) Offset a. Used in the setup mode after the kick mode, until the TBAL adjustment is completed. b.
  • Page 108 1.3 AUTOMATIC ADJUSTMENT FUNCTION In this system, all the circuit adjustments are automated inside the CD of the LSI. All adjustments are performed whenever a disc is inserted or the CD mode is selected by pressing the source key. Details of each adjustment will be explained below. 1.3.1 TE, FE, and RF offset auto-adjustment In this adjustment the TE, FE, and RF amplifier offsets of the preamplifier block in POWER ON are adjusted to the respective target values with the REFO as reference.
  • Page 109 1.3.4 Focus and tracking AGC This adjustment is to automatically adjust the focus and tracking servo loop gains. Adjusting procedure 1) Introduce disturbance to the servo loop. 2) The error signals (FE and TE) when disturbance is introduced are extracted through the band pass filter, to obtain the G1 and G2 signals.
  • Page 110 1.3.8 Coefficient display of adjustment results For some of the adjustments (FE and RF offset, FZD cancel, F and T gains, and RFAGC), the adjustment results can be displayed and confirmed in the test mode. The coefficient display in each auto adjustment is as follows: 1) FE and RF offset Reference value = 32 (coefficient of 32 indicates that no adjustment is required) The value is displayed in the unit of approximately 32 mV.
  • Page 111 1.4 POWER SUPPLY AND LOADING BLOCK For the power supply for this system, the VD (7.5 ± 0.5 V) and the VDD (3.3 ± 0.165 V), which are supplied from the motherboard, are used. The two power supplies, the VD mentioned above (for the drive system), and the VDD (for the LSI: 3.3 V), are used in this system.
  • Page 112 The load/eject operation is controlled with the status changes of the HOME switch (also used for clamp detection) on the mechanism unit and the three switches on the control unit. The ON/OFF statuses of these switches are respectively detected at the input port of the microcomputer. Using the detection results in the microcomputer, each status (A to E) is determined.

Digital audio data is transmitted to the mechanism through the USB block of LSI. The mechanism will operate iPod by transmitting commands to iPod instead of file reproduction process and so forth. Therefore the reproducible format and functions need to be compliant with iPod.
