Two-line driving circuit This circuit drives two-line of 150Ω. However, it may cause to lose synchronization by an input signal of large APL change (100% white signals more than 1Vp-p). Confirm the large APL change waveform (100% white signals more than 1Vp-p) and evaluate sufficiently. -9- A NJM2583A QTYPICAL CHARACTERISTICS Voltage Gain vs. Frequency SC,V,SY 10 8 10 -10 Delay[sec] Gain[dB] 0 -20 -30 -8 6 10 -8 4 10 -8 2 10 -8 SC V(SC) V(SY) SY -40 5 6 10 7 -2 10 8 10 -8 5 6 10 10 Frequency[Hz] 10 7 8 10 Frequency[Hz] Voltage Gain vs. Frequency Y,Pb,Pr(13.5MHz) 10 SC V(SC) V(SY) SY 0 10 10 Group Delay vs. Frequency SC,V,SY Group Delay vs. Frequency Y,Pb,Pr(13.5MHz) -8 8 10 Y(13.5Mhz) Pb(13.5MHz) Pr(13.5MHz) -8 6 10 -10 Delay[sec] Gain[dB] 0 -20 -8 4 10 -8 2 10 -30 0 Y(13.5MHz) Pb(13.5MHz) Pr(13.5MHz) -40 -8 5 6 10 10 7 10 -2 10 8 10 Frequency[Hz] 10 5 6 10 7 10 10 8 10 Frequency[Hz] Voltage Gain vs. Frequency Y,Pb,Pr(30MHz) 8 10 Group Delay vs. Frequency Y,Pb,Pr(30MHz) -8 Y(30MHz) Pb(30MHz) Pr(30MHz) -10 Delay[sec] Gain[dB] 0 -20 6 10 -8 4 10 -8 2 10 -8 -30 0 Y(30MHz) Pb(30MHz) Pr(30MHz) -40 5 10 6 7 10 10 Frequency[Hz] - 10 - 8 10 -2 10 -8 5 10 6 10 10 Frequency[Hz] 7 8 10 A NJM2583A [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
