Input Pins
DVDRFP,
DVDRFN
1,2
I
RF Signal Inputs. Differential RF signal attenuator input pins
CORF
63
I
RF Signal Input. Signal-ended RF signal attenuator input pin
AIP, AIN
59,60
I
AGC Amplifier Inputs. Differential AGC amplifier input pins
DIP, DIN
53,54
I
Analog Inputs for RF Single Buffer. Differential analog inputs to the RF
signal-ended output buffer and full wave rectifier
FDCHG#
32
I
Low impedance Enable, A TTL compatible input that actives the FDCHG
switches. A low level activates the switches and the falling edge of the
internal FDCHG triggers the fast decay for the MIRR bottom hold circuit
(open high)
HOLE1
49
I
Hold Control. A TTL compatible control pin which, when pulled high,
disables the RF AGC charge pump and holes the RF AGC amplifier gain
at its present values. (open high)
A, B, C, D
14-11
I
Photo Detector Interface Inputs. Inputs from the main beam Photo
detector matrix outputs.
A2,B2,C2,D2
8-5
I
Photo Detector Interface Inputs. AC coupled inputs for the DPD from the
beam Photo detector matrix outputs.
E, F
16-15
I
CD tracking Error Inputs. Inputs from the CD photo detector error outputs.
PD1, PD2
3-4
I
CD Photo detector Interface Inputs. Inputs from the CD photo detector
error outputs
ME1
40
I
Mirror Envelope Input. The SIGO envelope input pin.
MIN
35
I
RF signal Input for Mirror. AC coupled inputs for the mirror detection
circuit from the pull-in signal output. (PI)
DVDPD
21
I
APC Input DVD APC input pin from the monitor photo diode.
CDPD
23
I
APC Input CD APC input pin from the monitor photo diode.
LDON#
25
I
APC Output On/Off. APC output control pin. A low level activates the LD
output. (open high)
Output Pins
ATOP.ATON
62,61
O
Differential Attenuator Output. Attenuator outputs
FNP, FNN
52,51
O
Differential Normal Output. Filter normal outputs.
SIGO
57
O
Signal Ended Normal Output. Single normal output.
CDRFDC
64
O
CD RF Signal Output. Signal-ended RF output.
FE
42
O

Center Error Signal Output. Center error output reference to VCI
MEVO
34
O
SIGO Bottom Envelope Output. Bottom envelope for Mirror detection
DFT
37
O
Defect Output. Pseudo CMOS output. When a defect is detected, the
DFT/input goes high. Also the servo AGC output can be monitored at this
pin, when CAR bits 7-4 are ‘0011’
MIRR
29
O
Mirror Detect Output. Mirror Detect comparator output. Pseudo CMOS
output.
PI
36
O
Pull-in Signal Output. The summing signal output of A, B, C, D or PD1,
PD2 for mirror detection. Reference to VCI
DVDLD
22
O
APC output. DVD APC output pin to control the laser power.
CDLD
24
O
APC output. CD APC output pin to control the laser power.
