During recording, a chroma
signal that has been burst
emphasized, chroma
emphasized, and frequency
converted is output. During
8 ACK, the output DC goes to
0V. During recording, if
TEST1 is High the burst
emphasized signal is output.
Connects external time
constant for HPF of the
white/dark clipping
compensation circuit during
playback.

VG1
Input for de-emphasis circuit
during playback. The signal is
input to the de-emphasis
circuit through the clipping
compensation circuit.
