IN XTAL

3.5

4MHz oscillator inserted between the circuit and GND.

External input of the 4MHz signal possible. Insertion of

about 270k

Ω resistor between the circuit and GND

ensurescompatibility with 3.58MHz of VTR chroma

sub-carrier.

Insertion of about 270k

Ω resistor between the circuit and

VCC ensurescompatibility with 27MHz of D-STB reference.
