PB mode : Main converter output

Signal is applied through LPF from PB preamplifier outpu at PB

mode.

Compensation output is delivered when 160fH VCO frequency

deviates from specified frequency.

Main converter output at REC mode. When pin 9 voltage is raised

to 2.2V or greater, PB mode is enterd.

REC mode : AFC referenced to horizonta sync signal.

PB mode : APC filter referenced to 3.58MHz OSC.
