PIP Circuit
Figure 11
The PIP comes in two versions, Single Tuner with no tuner on the PIP panel and two tuner versions with the
second tuner located on the PIP module. Output of the second tuner is fed to the SAW FILTER 1901, and to
the Signal Processor 7914. Composite Video is fed to the Switch 7916, which selects between the PIP tuner or
selected Composite Video from the SSB. There are two sets of switches: one to select Video for the main
picture, CVBS-PIP_TUN1-2-CVBS-IN, and one to select Video for the PIP window. Selected Video for the PIP
window is fed to 7801, which selects between the output of 7916 or from AV1, AV2, or the Side Jack panel
(labeled Front In). The output of 7801 is buffered by a four-transistor amplifier and then fed to Pin 22 of 7803,
PIP processor. The PIP processor is controlled by the I2C buss (SDA and SCL). It is kept in sync by the
Vertical sync pulse (VFB) and the Horizontal sync pulse (SANDCASTLE). The PIP window video is output as
YUV to the YUV switch 7919. The signal is combined with the main picture YUV from the SSB panel on
connector 0205. The combined YUV signal is output on Pins 12, 11, and 10 to the SSB.
