LASER BEAM SAFETY PRECAUTIONS
CLASS 1 LASER PRODUCT CAUTION Invisible laser radiation when the unit is open. Do not stare into beam.
CAUTION: USE OF ANY CONTROLS, ADJUSTMENT, OR PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
Do not look directly at the laser beam coming from the pickup or allow it to strike against your skin.
This compact disc player uses a pickup that emits a laser beam. The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 1 foot away from the pickup lens when the diode is turned on. Do not look directly at the laser beam.
CAUTION:
Using controls and adjustment, or doing procedures other than those specified herein, may result in hazardous radiation exposure.

This symbol is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. This symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.
Caution:
To prevent electric shock do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.
WARNING To prevent fire or shock hazard, do not expose the unit to rain or moisture.
Attention: Pour prevenir les chocs electriques ne pas utiliser cetre fiche polarisee avec un prolongateur, une prise de courant ou une autre sortie de courant, sauf si les lames prevent etre inserees a fond-sans en laisser aucune partie a decouvert.
HANDLING LASER PICKUP
The laser diode in the optical system of this player can be damaged by electrostatic discharge from your clothes or your body. Proper electrostatic grounding for service personal is required during servicing.
BEFORE REPAIRING THE COMPACT DISC PLAYER
Preparation Human Body Grounding: Many of the components used in this compact disc player, including the laser pickup, are sensitive to electrostatic discharge. Service personal should be grounded with an electrostatic armband (1 Mohm). Caution: Static charge on clothing does not escape through a body grounding wrist band. Be careful not to contact the pickup or electrical components with your clothing. Workbench and Tool Grounding: A properly-grounded electroconductive plate (1Mohm) or metal sheet should be fitted to the workbench surface. Tools and instruments (such as soldering irons and scopes) should be grounded to prevent AC leakage.
Note: Laser diodes are so susceptible to damage from static electricity that, even if a static discharge does not ruin a diode, it can shorten its life or cause it to work improperly.

FUNCTION DESCRIPTION 1.RF Amp Block 1.1 RF Amplifier The optical currents inputted through pins PD1(A+C) and PD2(B+D) are converted into voltages through I-V amp, and they are added to RF summing amp. The voltage, converted from the photo diode (A+B+C+D) signal, is outputted through RFO(pin74) and the eye pattern can be checked at this pin.

Figure 4. RF amp circuit 1.2 Focus Error Amp The output of the focus error amp is the difference between I-V amp(1) output VA and RF I-V amp(2) output VB. The focus error bias voltage applied to the (+) of focus error amp can be changed by output voltage of D/A converter as shown in diagram, so that the offset of focus error amp can be adjusted automatically by controlling 5 bits counter switches. Focus error bias can be adjusted from the range of +100mV ~ -100mV by connecting the resistor on pin 63 (FEBIAS).

1.3 Tracking Error Amp The optical currents detected from the side photo diode (E and F) pf pick-up are inputted to the E and F pin and converted into voltage signals by E I-V and F I-V amp. The output of tracking error amp generates the difference between E I-V AMP and F I-V AMP voltage output. The E-F balance can be adjusted by modifying the gain of E I-V AMP, and the tracking gain can be adjusted automatically by controlling the peak voltage at pin TE2 by micom program.

1.7 Defect Circuit The RFO signal bottom, after being inverted, is held with two time constants of long and short. The short time-constant bottom hold is done for a disc mirror defect more than 0.1msec, the long timeconstant bottom hold is done with the mirror level prior to the defect. By differentiating this with a capacitor coupling and shifting the level, both signals are compared to generate the mirror defect detection signal.

2.Servo Block 2.1 Focus Servo Block When defect is "H"(the defect signal is detected), the focus servo loop is muting in case of focus phase compensation. At this time, the focus error signal is outputted through the low pass filter formed by connecting a capacitor(0.1uF) and a built-in 470K resistor to the FDFCT pin(pin 60). Accordingly, the focus error output is held at the error value just before defect error during defect occurring. The peak frequency of focus loop phase compensation is at about 1.2KHz when the resistor connected to FSET pin(pin 6) is 510K, and it is inversely proportional to the resistor connected to the FSET pin. While the focus search is operating, the FS4 switch is on and then the focus error signal is isolated, accordingly the focus search signal is outputted by FEO pin(pin 48). When the FS2 switch is on(focus on), the focus servo loop is on and the focus error signal from FE2 pin(pin 58) is outputted through the focus servo loop.

2.2 Tracking Servo Block During detection of defect, the tracking error signal is outputted through the tracking servo loop after passing the low pass filter formed by connecting a capacitor(0.1uF) and a built-in 470K resistor to the TDFCT pin(pin57) in case of tracking phase compensation. The value of tracking gain up/down can be controlled by TGU and TG2 pin. The peak frequency of tracking loop phase compensation, the dynamic range and offset of opamp can be adjusted by changing the value of resistor connected to FSET pin same as focus loop. In case of unstable status of actuator after jumping, the ON/OFF of tracking loop is controlled by TM7 switch of break circuit. After 10-track jumping, servo circuit gets out of the liner range and actuator's tracking becomes occasionally unstable. Hence unnecessary jumping with many tracking error should be prevented.

2.4 Spindle Servo Block The 20K resistor and 0.33uF capacitor form the 200Hz low pass filter, and the carrier component of spindle servo error signals is eliminated. In CLV-S mode, SMEF becomes "L" and pin 25 low pass filter fc lowers, strengthening the filter further. The characteristics of high frequency phase compensation in focus tracking servo and the characteristics of cut off frequency in CLV low pass filter are tested by FSET pin.

DESCRIPTION
The PCM1732 is designed for mid- to high-grade digital audio applications which achieve 96kHz sampling rates with 24-bit audio data, such as High Definition Compatible Digital (HDCD) CD players, DVD players, mini-disc players and AV receivers. PCM1732 uses a newly-developed "enhanced, multilevel delta-sigma modulator" architecture that improves audio dynamic performance and reduces jitter sensitivity. The internal digital filter operates at 8x oversampling at a 96kHz sampling rate, with 120dB stopband attenuation.

ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(3) Rush current absorption circuit When a high voltage (caused by such as a motor reversal) is generated on OUT1 and OUT2, an internal comparator detects the high voltage and turns on an internal circuit that absorbs rush currents. (4) Drive circuit The forward direction of the motor connected between OUT1 and OUT2 corresponds to the current flow from OUT1 to OUT2, and the reverse direction corresponds to the current flow from OUT2 to OUT1. The output voltage (VOUT) applied to the motor is given by the equation : VOUT (V) = VZD * VCE (sat.) = VZD * 0.2 (IOUT = 100mA) where VZD is the zener voltage of the constant voltage diode (ZD) connected to pin 4. If Vref is left OPEN, the output voltage (VOUT) is given by the equation : VOUT (V) = VCC1 * VCE (sat.) (PNP) * 2VF * VCE (sat.) = VCC1 * 1.8 (IOUT = 100mA)
Forward / reverse control, forced stop, and rush current absorption are controlled by the combination of FIN and RIN input states. (1) Forward / reverse control circuit When FIN is HIGH and RIN is LOW, current flows from OUT1 to OUT2. When FIN is LOW and RIN is HIGH, current flows from OUT2 to OUT1 (refer to the truth table). (2) Forced stop circuit By setting RIN and FIN both HIGH or both LOW, power supply to the motor is shut down and a brake is applied by absorbing the motor counter-electromotive force.
