  • Page 60 Circuit Descriptions 6-4 Servo 6-4-1 Outline SERVO system of DVD is divided into Focusing SERVO, Tracking SERVO, SLED Linked SERVO and CLV SERVO (DISC Motor Control SERVO). 1) Focusing SERVO Focuses the optical spot output from object lens onto the disc surface. Maintains a uniform distance between object lens of Pick-up and disc (for surface vibration of disc).
  • Page 61 Circuit Descriptions 6-4-3 Operation 1) FOCUSING SERVO (1) FOCUS INPUT The focus loop is changed from open loop to closed loop, and the triangular waveform moves the object lens up and down (at pin 75 of SIC1 during Focus SERVO ON.) At that time, S curve is input to pin 65 of SIC1. ABAD (pin 39 of RIC1) signal, summing signal of PD A, B, C, D, is generated, and zero cross(2.5V) point occurs when S curve is focused and ABAD signal exceeds a preset,constant value.

  • Page 65 Circuit Descriptions 6-6 Video 6-6-1 Outline ZIC1(A/V decoder with video encoder) diverges from the 27MHz crystal, then generates VHSYNC and HSYNC. ZIC1(A/V decoder with video encoder) does RGB encoding,copy guard processing and D/A conversion of 8bit video data internally inputted from video decoder block by MIC1(Micom). Video signal converted into analog signal is outputted via amplifier of analog part.
  • Page 66 Circuit Descriptions 6-6-3 Amplifier (VIC1, VIC2 : BA7660) VIC1 and VIC2 are 6dB amplifier. Based on CVBS signal, the final output level must be 2Vpp without 75ohm terminal resitance. Because the level of video encoder output is only 1.1Vpp, the level is adjusted with the special amplifier.
