The video output is output from XP1 by the CVBS signal from U8 Pin 59.
PC signal input
PC signal or P is the R, G and B signals and HS RGB, VS RGB signals that are input from VGA
terminal through inputting interface. The three pins where the R, G and B signals are input are
connected respectively with BAV99, high speed protective bidirectional diodes. When the RGB
input level is too high, the diode will be broken down to reduce the level. On the contrary, when the
voltage is lower than 0V, the diode will be opened, that is, to ensure that the RGB input level is
between 0-5V (regardless of the voltage drop of the diode). HS RGB signal is connected with the
protective diode D30 and VS RGB signal with D33. Both diodes have the stabilized voltage of 5.6V.
R319 and C313, and R331 and C314 make up of the RC filters. The output RGB signal and YPBPR
component input are selected in P15V330Q. The output signals go into U8 Pins16, 17, 22, 23, 24, 25,
26 and 27. One route of PC signal may be directly input to Pins 29, 30, 31, 32, 33, 34, 34, 38 and 39.
U13 is of 24C02 type, which is used for bus buffering and whose pins have the following functions:
Pin 1 2 3 4 5 6 7 8
Meaning NC NC NC GND SDA SCL VCLK VCC
voltage
The audio signal includes the HD L signal which is output from XS2A to R126 and C134 (2.2UF),
where it is coupled and sent to U8 Pin 71, and HD R signal that passes R129 and C135 (2.2UF),
where it is coupled and sent to U8 Pin 72.
