Type
I RF Signal Inputs. Differential RF signal attenuator input pins
I RF Signal Inputs. Single-ended RF signal attenuator input pin
I AGC Amplifier Inputs. Differential AGC amplifier input pins
Analog inputs for RF Single Buffer. Differential analog inputs to the RF single-ended output buffer
I
and full wave rectifier
Low Impedance Enable. A TTL compatible input pin that activates the FDCHG switches. A low
I level activates the switches and the falling edge of the internal FDCHG triggers the fast decay for
the MIRR bottom hold circuit. (open high)
Hold Control. A TLL compatible control pin which, when pulled high, disables the RF AGC charge
I
pump and holds the RF AGC amplifier gain at its present value. (open high)
I Photo Detector Interface Inputs. Inputs from the main beam Photo detector matrix outputs
Photo Detector Interface Inputs. AC coupled inputs for the DPD from the main beam Photo
I
detector matrix outputs
I CD tracking Error Inputs. Inputs from the CD photo detector error outputs.
I CD Photo detector Interface Inputs. Inputs from the CD photo detector error outputs
I Mirror Envelope Inputs. The SIGO envelope input pin
RF signal Input for Mirror. AC coupled inputs for the mirror detection circuit from the pull-in signal
I
output. (PI)
I APC Input. DVD APC input pin from the monitor photo diode
I APC Input. CD APC input pin from the monitor photo diode
I APC Output On/Off. APC output control pin. A low level activates the LD output. (open high)
O Differential Attenuator Output. Attenuator outputs
O Differential Normal Output. Filter normal outputs
O Single Ended Normal Output. Single-ended RF output
O CD RF Signal Output. Single ended CD RF summing output
O Focusing Error Signal Output. Focus error output reference to VCI
O Tracking Error Signal Output. Tracking error output reference to VCI
