Remarks
Vdd/2 output (1.65V)
3.3V is connected.
When frequency is increased, the
filters excepting the servo LPF are
shifted to high frequency side.
Low DPD output: Mute
Used in the open state.
DC voltage varies by RFS.
DC voltage varies by RFS.
When TEB is raised, the gain on the
TP side and the delay amount on the
A+C side are increased.
Adjusting range: GND - Vdd
When FEB is raised, the gain on the
A+C (FP) side is increased.
Adjusting range: GND - Vdd
When DPDB is raised, the delay
amount on the A•B side is increased.
Adjusting range: GND - Vdd
Used in the open state.
Used in the open state.
When EQB is raised, the boost increases.
Adjusting range: GND - Vdd
