the SSB panel on connector 0205. The
combined YUV signal is output on Pins 12, 11,
and 10 to the SSB.
PIP Switching (Figure 12)
Control for the PIP panel is performed by
7910 via the I2C buss. SEL_TUNER1 and
SEL_TUNER2 control the composite
switching to the SSB panel. S1, S2, and S3
control the tuner aux switching IC 7801.
PIP Power Supply (Figure 13)
The PIP panel is powered by +5 volt, +8
volt, and +33 volt supplies from the Large
Signal Board (LSB). A 3.3 volt regulator
supplies power to the PIP processor, 7803.
