DVCC
Outputs a sub carrier with
the same phase as B-Y.
When not in use, connection
to VCC prevents output and
allows for 600µA of current
saving.

VTH is at 2.5V. Input a pulse
with an amplitude larger than
VTH ±0.5V.

AVCC
Inputs BF (burst flag) pulse.
During analog burst, the
input pulse smoothens the
waveform.
