Generalized I/O terminal 3
Generalized I/O terminal for command identification. Pull-down resistor incorporated. When used as the same funct
i
as LC78622E, open circuit or ground. ("H" position: enables only generalized I/O command to be controlled. "L" po
s
enables all the commands to be controlled.)
Controlled by a serial data command from micro-computer. When not used, either
u
as input terminal and then ground or use as output terminal and then open circuit.
Terminal for de-emphasis monitor. De-emphais disk is being reproduced while in the "H" position. Or generalized O

terminal 6.
Output terminal for C2 flag.
Output terminal for automatic switching monitor between rough servo and phase control. (Rough servo on "H"positi
o
phase servo on "L".
Input terminal for track detection signals. Schmitt input.
Input terminal for tracking error signals. Schmitt input.
Output terminal for tracking-off.
Output terminal for tracking gain switching. "L" position increases gain.
Output for track jump control. 3 values can be output by a command.
Terminal for clock monitor for EFM data reproduction. 4.3218 MHz when phase locked.
Output terminal for synchronizing signal detection. "H" position when the synchronizing signals detected in EFM sig
n
match with the synchronizing signals generated internally.
Power terminal for R channel.
Output for disk motor control. 3 values can be output by a command.
DESCRIPTION
