PL700

connection with FC/MSC board

26ways connector

assuming that 1Vpp video signal with 75ohm terminated is input through SCART100 (AV3)

UV are inverted by Q609/Q612/Q610/Q613 to CbCr(U'V') at pin 25/24 and
those are adjusted to the level at 1.4Vpp

Y is amplified by Q608/Q611 to adjust the level at 1.4V for signal and 0.6V
for sync (2Vpp in total) at pin 26

sound level L and R at pin 6/4 should be 500mVrms on the condition that -

500mVrms audio is input through SCART100(AV3)

BG FM sound with 54% modulation is received
