    FL8385 FL8380 FUNCTION DESCRIPTION Tracking System To Focus System REF1 REF2 Subtraction GCTRL TBAL GCTRL TEOUT TBAL PDIC The tracking error output of E and F is given to Pin 25 (TEOUT). C8 is required for oscillation-proof. R10 is chosen such that TEOUT of Pin 25 become 1.4Vp-p.
  • Page 17 FL8385 FL8380 Focus System Subtraction GCTRL FBAL GCTRL PDIC FEOUT FBAL The focus error output of A, B, C and D are given to Pin 27. C4 is required for oscillation- proof. R7 is set such that FEOUT of Pin 27 becomes 1.46 Vp-p.
  • Page 18 FL8385 FL8380 RF, EQ, AGC NRFDET RFOUT DETECTION DETECTION GCTRL GCTRL The signals A, B, C and D input from PDIC are composed into the RF signal by the RF Addition Amp, then output from RFOUT of Pin 5. This Amp is designed so that RFOUT is about 0.5 Vp-p for normal CD disc (about 0.4 Vp-p for CDR and 0.12 Vp-p for CDRW).
  • Page 19 FL8385 FL8380 LDON LASER UNIT 170mV The laser diode has large negative temperature characteristic in its optical output when driven with a constant current on laser diode. Therefore, the output on processing monitor photo diode, must be a controlled current for getting regular output power, thus the APC (Auto Power Control) circuit is composed.
