NOV. 2002 Printed in Japan 1 2 3 4 A 1. CIRCUIT DESCRIPTIONS Recently, Many CD LSIs have been one-chip LSIs where RF amplifier, DSP, audio DAC, post filter, and other circuits are integrated. This product uses this type CD LSI, UPD63712GC, which includes all functions necessary for CD player control. Basically, this system outputs the analog signal, and the digital output can be supported.

After I/V-converted by the preamplifier with built-in photo detectors (inside the pickup), the signals are applied to the preamplifier block in the CD LSI UPD63712GC (IC201). After added by the RF amplifier in this block, these signals are used to produce necessary signals such as RF, FE, TE, and TE zero-cross signals. The CD LSI employs a single power supply system of + 3.3V. Therefore, the REFO (1.65V) is used as the reference voltage both for this CD LSI and the pickup. The LSI produces the REFO signal by using the REFOUT via the buffer amplifier and outputs from the pin 90. All the measurements should be made based on this REFO. Caution: Be careful not to short the REFO and GRD when measuring. A B 1.1.1 APC (Automatic Power Control) A laser diode has extreme
