Remarks
1/2 of Vdd (2.1V)
Approx. 4.2V
Frequency increase results in shift to
higher filter frequency except for servo LPF.
DPD output at Low: Mute
Used by connecting to GND.
DPDB increase brings delay capacity
increase on sides A and B.
TEB increase brings increase in gain on TP
side and in delay capacity on sides A and C.
FEB increase brings increase in gain on
sides A and C (FP).
Frequency division OFF at High
Connected to GND via C.
Group delay by raising EQD: rise rightward
Boost quantity up by raising EQB.
Shift to higher frequency by raising EQF.
Used by connecting to GND.
