Description of Functions
RF Block
The RF signal processing is performed by this circuit.
The output is separated to AC and DC. The AC is the capacitance-coupled input via the equalizer circuit and
used for the EFM demodulation signal processing. The DC contains the DC component and is used for the
mirror, defect and FOK signal processings.
The VCA function is provided for both the AC and DC signal processing systems. Pin 28 is the control voltage
input pin. (See the characteristics graphs on page 19 and page 20 for the gain and control voltage.)

RF Equalizer
The equalizer function is provided for the AC signal processing system for the EFM signal demodulation.
The each filter is constructed in the Bessel type which has the little group delay difference.
The cut-off frequency and boost amount can be set by the external resistors connected to Pins 26 and 27.
(See the characteristics graphs on page 19 for the cut-off frequency and boost amount.)

RF Amplifier
The signal currents from the photodiodes A, B, C and D are I-V converted and input to Pins 3, 4, 5 and 6.
These signals are added by the RF summing amplifier, inverted by the RF drive amplifier and output to Pin 32.
The VCA control voltage on Pin 28 is used for the gain adjustment.

Tracking Error Amplifier
The signal current from the photodiode F is I-V converted and input to Pin 10 via the input resistor. The signal
current from the photodiode E is I-V converted and input to Pin 9 after its gain is adjusted by the volume.
These signals undergo operational amplification at the tracking error amplifier, VCA and tracking drive amplifier
and they are output to Pin 13.

Mirror Circuit
The mirror circuit performs peak and bottom hold after RFI signal has been amplified. The peak hold is
executed with the time constant which follows the traverse signal of 100kHz for L/L mode (either of Pins 23 or
24 is connected to GND) and maximum 700kHz (adjustable with the DC voltage on Pin 17) for L/H, H/L, H/H
modes. The bottom hold is executed with the time constant which follows the rotation cycle envelope
fluctuation.

MIRR
The mirror signal is output by comparing to the signal K (2/3 level of the J peak value which is peak-held with a
large time constant) where the difference of hold signals H and I is obtained. The mirror output is low for tracks
on the disc and high for the area between tracks (the mirror areas). In addition, a high signal is output when a
defect is detected. The mirror hold time constant must be sufficiently large in comparison with the traverse
signal.

APC Circuit
When the laser diode is driven by a constant current, the optical power output has extremely large negative
temperature characteristics.
The APC circuit is used to maintain the optical power output at a constant level. The laser diode current is
controlled according to the monitor photodiode output.
APC is ON by connecting APC_ON pin to GND; it is OFF by connecting the pin to Vcc.
