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.
