1) Outputs VCO OUT signal to BF VCO
2) Outputs white/dark-clipped Y
1) Cuts APC loop and inputs signal from
2) During REC, outputs burst emphasis
3) For the PB chroma feedback comb
Sync Separation does not operate.
(External input to COMP SYNC (Pin 24) is
possible).
Fixes the correlation pulse High so that
there is always correlation.
Detects correlation.
Sharpness block through (does not pass
through fsc Trap, Sharpness, LPF and
EQ)
ACK SW does not operate according to
ACK DET; always fixed to color mode.
ACK operation is performed according to
ACK DET.
Switches the feedback amount of the FBC
(feedback comb).
During recording, the signal input to EXT
C IN (Pin 53) is input directly to the ACC
amplifier.
Refer to Table 1.

The dark clipping level is switched as
shown below. (when white clipping is
235% and WDC (Pin 27) is left open)
Switches the amount of the dark clipping
level offset to the white clipping level,
which can be varied in steps of 10%.
Disables MUTE for the chroma signal by
the MASK signal.
Mutes the chroma signal by the MASK
signal.
PAL (chroma function)
NTSC
During recording, inputs fsc, locked to
burst, from CAM FSC SHP (Pin 60)
without performing APC with the input
chroma signal, and then performs
frequency conversion using this fsc.
Recordable time can be reduced to 0.2
seconds or less from power saving mode
with separate input.
1) S•PS (31.S=Low)
2) S•PS (31.S=High)
Performs Yd playback during playback.
