(Note 2) Explanation of symbols

• Vv : VIDEO IN output voltage at Pin3

• Voso : OSC output voltage at Pin8

• Gvvh : RF OUT output voltage at Pin1

OSC(Pin8) input = Voso+0.3V

• Gvvl : RF OUT output voltage at Pin1

OSC(Pin8) input = Voso-0.3V

• Mwh : RF OUT output voltage at Pin1

OSC (Pin 8) input = Voso+0.3V,VIDEO IN(Pin3) input=Vv + 0.41V

• Mwl : RF OUT output voltage at Pin1

OSC (Pin 8) input = Voso-0.3V,VIDEO IN(Pin3) input=Vv + 0.41V

• Wch : RF OUT output voltage at Pin1

OSC (Pin 8) input = Voso+0.3V,VIDEO IN(Pin3) input=Vv + 0.75V

• Wcl : RF OUT output voltage at Pin1

OSC (Pin 8) input = Voso-0.3V,VIDEO IN(Pin3) input=Vv + 0.75V

• Gva : RF OUT output level at Pin1(4.5MHz Sine wave [peak to peak])

OSC(Pin8) input = Voso+0.6V
