PBREC signal mode
RFGCA:
RFDC:
PBREC mode
This is an amplifier which controls the gain of the video chroma RF signal input to PBRFC. The RFCONT
voltage can be varied from (20/50) V
The input signal level and frequency are respectively 200mVp-p (typ.) and DC up to approx. 1.5MHz.
RFDC is a DC bias circuit which operates when the PBREC signal is output by the DRV. The DC bias
potential is 3V.
