Moreover, since the load resistance is 150 Ω (75 Ω + 75 Ω) for the video driver, the capacity of the coupling capacitor must be on the order of 1000 μF if you take into account the low band passband. (Fig.3) For an amplifier operated from dual power supplies (+ supply), since the operating point can be at GND level, a coupling capacitor for preventing output of direct current is not needed. Moreover, since a coupling capacitor is not needed, in principle, there is no lowering of the low band characteristic at the output stage. (Fig.4) 2) Occurrence of negative voltage due to charge pump circuit A charge pump, as shown in Fig. 5, consists of a pair of switches (SW1, SW2) and a pair of capacitors (flying capacitor, anchor capacitor). Switching the pair of switches as shown in Fig. 5 causes a negative voltage to occur by shifting the charge in the flying capacitor to the anchor capacitor as in a bucket relay. In this IC, by applying a voltage of +3 V, a negative voltage of approximately -2.8 V is obtained. www.rohm.com © 2009 ROHM Co., Ltd.

Accordingly, while there is +3 V single-supply operation, since a dual-supply operation amplifier is used, an output coupling capacitor is not needed.

Therefore, since a BH769xxGU or BH76706GU operates normally even if there is no synchronization signal in the input signal, it is compatible with not only normal video signals but also chroma signals and R.G.B. signals and has a wide application range. Moreover, concerning sag (lowering of low band frequency) that occurs at the input pin and becomes a problem for the resistance termination method, since the input termination resistor is a high 150 kΩ, even if it is combined with a small capacity input capacitor, a sag characteristic that is not a problem in actual use is obtained. In evaluating the sag characteristic, it is recommended that you use an H-bar signal in which sag readily stands out. (Fig. 8 to Fig. 10) www.rohm.com © 2009 ROHM Co., Ltd.

Wiring from the decoupling capacitor C4 to the IC should be kept as short as possible. Moreover, this capacitor's capacitance value may have ripple effects on the IC, and may affect the S-N ratio for signals, so we recommend using as large a decoupling capacitor as possible. (Recommended C4: 3.3 µF, B characteristics, 6.3 V or higher maximum voltage) Make mount board patterns follow the layout example shown on page 10 as closely as possible. 2. Capacitors to use In view of the temperature characteristics, etc., we recommend a ceramic capacitor with B characteristics. 3. The NVCC (C1 pin) terminal generates a voltage that is used within the IC, so it should never be connected to a load unless absolutely necessary. Moreover, this capacitor (C2) has a large capacitance value but very little negative voltage ripple. (Recommended C2: 1.0 μF, B characteristic, 6.3 V or higher maximum voltage) 4. Capacitors C1 and C4 should be placed as close as possible to the IC. If the wiring to the capacitor is too long, it can lead to intrusion of switching noise. (Recommended C1: 1.0 µF, B characteristics, 6.3 V or higher maximum voltage) 5. The HPF consists of input coupling capacitor C3 and 150 kΩ of internal input impedance. Be sure to check for video signal sag before determining the C3 value. The cut-off frequency fc can be calculated using the following formula. fc = 1/(2π×C3×150kΩ) (Recommended C3: 1.0 μF, B characteristic, 6.3 V or higher maximum voltage) 6. The output resistor R2 should be placed close to the IC. 7. If the IC is mounted in the wrong direction, there is a risk of damage due to problems such as inverting VCC and GND. Be careful when mounting it. 8. A large current transition occurs in the power supply pin when the charge pump circuit is switched. If this affects other ICs (via the power supply line), insert a resistor (approximately 10 Ω) in the VCC line to improve the power supply's ripple effects. Although inserting a 10 Ω resistor lowers the voltage by about 0.2 V, this IC has a wide margin for low-voltage operation, so dynamic range problems or other problems should not occur.

For this IC, since the output waveform is GND-referenced and swings positive and negative, a normal Zener diode cannot be used.
