The SAG correction reduces output coupling capacitor values. However, this circuit may cause to SAG deterioration, and lose synchronization by luminance fluctuation. Adjust the C1 value, checking the waveform containing a lot of low frequency components like a bounce waveform (Worst condition waveform of SAG). Change the capacitor of C1 into a large value to improve SAG. (2) SAG correction unused circuit We recommend this circuit when there is no space limitation. Connect the coupling capacitor after connecting the Vout pin and Vsag pin. The recommended value is 470µF or more. (3) 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. -4- NJM41031 Q APPLICATION CIRCUIT 1 (in case DC-coupling, 1-drive circuit) Input 10uF 0.1uF 0.1u + 75Ω + 6 5 4 GND V+ VIN Power Save Vout Vsag 1 2 3 75Ω Output Q APPLICATION CIRCUIT 2 (in case DC-coupling, 2-drive circuit) Input 10uF 0.1uF 0.1u + + 6 5 4 V+ GND VIN Power Save Vout 1 Vsag 2 75Ω Note) 0.4V typ. is always output from Vout. 75Ω 3 75Ω Output 1 Output 2 -5- NJM41031 Q TERMINAL DESCRIPTION PIN No. SYMBOL VOLTAGE EQUIVALENT CIRCUIT 32Kohm 1 Power Save - 48Kohm V+ 2 Vout 0.4V V+ 3 Vsag Vin V+ 0.4V V+ 4 V+ V+ 1.7V V+ -6- 5 GND - 6 V+ - NJM41031 QTYPICAL CHARACTERISTICS Gain vs. Freqency Operating Current vs. Supply Voltage o V+=5V Ta=25 C Vin=1.0Vpp Sine Signal Input 10 30 Operating Current [mA] 0 -20 -30 RL=150ohm RL=75ohm -40 DC -50 0.1 1 10 100 20 10 0 0 Freqency [MHz] 1 20 0 5.0 5.5 6.0 Maximam Output Voltage Swing [V] Operating Current at Power Save Mode [uA] 40 4.5 6 3.00 2.50 2.00 4.0 4.5 5.0 5.5 6.0 Supply Voltage [V] Low Pass Filter Charactrestic vs. Supply Voltage 6.50 6.00 5.50 5.5 Supply Voltage [V] 6.0 Low Pass Filter Charactrestic [dB] 1.0Vpp, 100kHz, Sine Signal Input 5.0 5 3.50 Voltage Gain vs. Supply Voltage 4.5 4 Total Harmonic Distotion=1%, 100KHz 4.00 Supply Voltage [V] 4.0 3 Maximam Output Voltage Swing vs. Supply Voltage 60 4.0 2 Supply Voltage [V] Operating Current at Power Save Mode vs. Supply Voltage Voltage Gain [dB] Gain [dB] -10 1.0Vpp, 6.75M/100kHz, Sine Signal Input 1.0 0.5 0.0 -0.5 -1.0 4.0 4.5 5.0 5.5 6.0 Supply Voltage [V] Ver.2 -7- NJM41031 QTYPICAL CHARACTERISTICS Differential Gain vs. Supply Voltage 1.0Vpp, 10step Video Signal Input 1.0Vpp, 108M/100kHz, Sine Signal Input -20 3.00 Differential Gain [%] Low Pass Filter Charactrestic [dB] Low Pass Filter Charactrestic vs. Supply Voltage -30 -40 -50 2.00 1.00 0.00 4.0 4.5 5.0 5.5 6.0 4.0 4.5 Differential Phase vs. Supply Voltage 90 Signal to Noise Ratio [dB] Differential Phase [deg] 6.0 1.0Vpp, White 100%Video Signal Input 3.00 2.00 1.00 0.00 80 70 60 4.0 4.5 5.0 5.5 6.0 4.0 4.5 5.0 5.5 6.0 Supply Voltage [V] Supply Voltage [V] Switching Voltage Level (High Level) vs. Supply Voltage Switching Voltage Level (Low Level) vs. Supply Voltage 3 3 Switching Voltage Level [V] Switching Voltage Level [V] 5.5 Signal to Noise Ratio vs. Supply Voltage 1.0Vpp, 10step Video Signal Input 2 1 0 4.0 4.5 5.0 5.5 Supply Voltage [V] -8- 5.0 Supply Voltage [V] Supply Voltage [V] 6.0 2 1 0 4.0 4.5 5.0 5.5 Supply Voltage [V] 6.0 NJM41031 QTYPICAL CHARACTERISTICS Operating Current at Power Save Mode vs. Temperature Operating Current vs. Temperature 60 Operating Current at Power Save Mode [uA] Operating Current [mA] 30 25 20 15 40 20 0 10 -50 -25 0 25 50 75 100 -50 125 -25 Ambient Temperature [ C] Maximam Output Voltage Swing vs. Temperature 75 100 125 1.0Vpp, 108M/100kHz, Sine Signal Input Low Pass Filter Charactrestic [dB] Maximam Output Voltage Swing [V] 50 -20 4 3 2 1 -30 -40 -50 0 -50 -25 0 25 50 75 100 125 -50 -25 Ambient Temperature [0C] 0 25 50 75 100 125 Ambient Temperature [0C] Low Pass Filter Charactrestic vs. Temperature Low Pass Filter Charactrestic vs. Temperature 1.0Vpp, 108M/100kHz, Sine Signal Input 1.0Vpp, 6.75M/100kHz, Sine Signal Input -20 Low Pass Filter Charactrestic [dB] 1.00 Low Pass Filter Charactrestic [dB] 25 Low Pass Filter Charactrestic vs. Temperature Total Harmonic Distotion=1%, 100kHz 5 0 Ambient Temperature [0C] 0 0.50 0.00 -0.50 -30 -40 -50 -1.00 -50 -25 0 25 50 75 0 Ambient Temperature [ C] 100 125 -50 -25 0 25 50 75 100 125 Ambient Temperature [0C] -9- NJM41031 QTYPICAL CHARACTERISTICS Differential Gain vs. Temperature Differential Phase vs. Temperature 1.0Vpp, 10step Video Signal Input Differential Phase [deg] Differential Gain [%] 1.0Vpp, 10step Video Signal Input 3.00 3.00 2.00 1.00 0.00 -50 -25 0 25 50 75 100 2.00 1.00 0.00 125 -50 Ambient Temperature [0C] 25 50 75 100 125 Switching Voltage Level (High Level) vs. Temperature 1.0Vpp, White 100% Video Signal Input Switching Voltage Level [V] 3 80 70 60 -50 -25 0 25 50 75 100 125 Ambient Temperature [0C] 2 1 0 -25 0 25 50 75 Ambient Temperature [0C] - 10 - 1 0 -50 -25 0 25 50 75 Ambient Temperature [ C] 3 -50 2 0 Switching Voltage Level (Low Level) vs. Temperature Switching Voltage Level [V] Signal to Noise Ratio [dB] 0 Ambient Temperature [0C] Signal to Noise Ratio vs. Temperature 90 -25 100 125 100 125 NJM41031 [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
