Horizontal Steady State Supply Pin :
Steady state supply is used by horizontal
circuit startup. Internal voltage regulating
circuit is present
DC
6.5 V
40
Horizontal AFC 2 Filter Pin :
FBP and IC internal pulse phase
difference is compared. At Pin40, a
capacitor is connected for charging
and discharging this current
The current from the picture centre
position adjustment DAC establishes
DC by chaging and discharging current
Time difference from Hout to FBP-in
depends on V
40
which changes the slice
level of internal sawtooth waveform
DC
1.5 V to 3.5 V
41
Horizontal AFC 1 Filter Pin :
Horizontal synchrous signal and IC
internal pulse phase difference is
compared. At Pin41, a capacitor is
connected for charging and discharging
current
R1, R2, C1, C2, are lag-lead filter used
by AFC 1
