Remarks
4MHz oscillator inserted between the circuit and GND.
External input of the 4MHz signal possible. Insertion of
about 270kΩ resistor between the circuit and GND
ensurescompatibility with 3.58MHz of VTR chroma
sub-carrier.
Insertion of about 270kΩ resistor between the circuit and
VCC ensurescompatibility with 27MHz of D-STB reference.
