Remarks
Vdd 1/2
4.2V (3.3V)
When frequency is increased, the
filters excepting the servo LPF are
shifted to high frequency side.
Low DPD output: Mute
To be connected to GND
To be connected to GND
When D PDB is raised, the A/B
side delay increases.
When TEB is raised, the TP side
gain increases and the A+C side
delay increases.
When FEB is raised, the A+C (FP)
side gain increases.
High: Frequency division OFF
To be connected to VrD, or to GND
through C
When EQD is raised, the group
delay increases at the right side.
When EQB is raised, the boost increases.
When EQF is raised, shift to the
high frequency side occurs.
To be connected to GND
Positive polarity when this terminal
is connected to Vcc.
