(Note 2) Explanation of symbols
• Vv : VIDEO IN output voltage at Pin1
• V11h : CH1 output voltage at Pin11
CH SW (Pin13) input = 2.5V
• V12h : CH1 output voltage at pin12
CH SW (Pin13) input = 0.5V
• Gvvh1: RF OUT output voltage at Pin4
VIDEO IN (Pin 1) input = Vv, CH1 (Pin11) = V11h + 0.15V, CH SW (Pin13) input = 2.5V
• Gvvl1 : RF OUT output voltage at Pin4
VIDEO IN (Pin 1) input = Vv, CH1 (Pin11) = V11h - 0.15V, CH SW (Pin13) input = 2.5V
• Gvvh2 : RF OUT output voltage at Pin4
VIDEO IN (Pin 1) input = Vv, CH2 (Pin12) = V12h + 0.15V, CH SW (Pin13) input = 0.5V
• Gvvl2 : RF OUT output voltage at Pin4
VIDEO IN (Pin 1) input = Vv, CH2 (Pin12) = V12h - 0.15V, CH SW (Pin13) input = 0.5V
• Mwh : RF OUT output voltage at Pin4
VIDEO IN (Pin 1) input = Vv + 0.43V, CH1 (Pin11) = V11h + 0.15V, CH SW (Pin13) input = 2.5V
• Mwl : RF OUT output voltage at Pin4
VIDEO IN (Pin 1) input = Vv + 0.43V, CH1 (Pin11) = V11h - 0.15V, CH SW (Pin13) input = 2.5V
• Wch : RF OUT output voltage at Pin4
VIDEO IN (Pin 1) input = Vv + 0.8V, CH1 (Pin11) = V11h + 0.15V, CH SW (Pin13) input = 2.5V
• Wcl : RF OUT output voltage at Pin4
VIDEO IN (Pin 1) input = Vv + 0.8V, CH1 (Pin11) = V11h - 0.15V, CH SW (Pin13) input = 2.5V
• VPs : P/S output voltage at Pin6
CARRIER OFF SW (Pin 2) input = 2.5V
• Psh : RF OUT output voltage at Pin4
P/S (Pin 6) input = VPs + 0.2V, CH1 (Pin11) = 2.4V, CH SW (Pin13) input = 2.5V
• Psl : RF OUT output voltage at Pin4
P/S (Pin 6) input = VPs - 0.2V, CH1 (Pin11) = 2.4V, CH SW (Pin13) input = 2.5V
