Description
Not for use.

Not for use.
Keep open.
DVCC
200
Outputs a sub carrier with
the same phase as B-Y.
When not in use, connection
140
to VCC prevents output and
allows for 600µA of current
saving.
500µA
Determining phase to 4FSC
is impossible.
DGND
5V
0V
Inserts a pulse slightly larger
AVCC than BF on both ends.

40µA
AGND
VTH is at 2.5V. Input a pulse
with an amplitude larger than
VTH ±0.5V.
Inputs BF (burst flag) pulse.
During analog burst, the
AVCC ^{input pulse smoothens the}
waveform.
5V

The input pulse waveform
140
becomes the envelope of the
10
analog burst waveform.
