ͶDescription
Due to a built-in charge pump circuit, this video driver does not require the large capacity tantalum capacitor at the video
output pin that is essential in conventional video drivers. Features such as a built-in LPF that has bands suited to mobile
equipment, current consumption of 0 μA at standby, and low voltage operation from as low as 2.5 V make it optimal for digital
still cameras, mobile phones, and other equipment in which high density mounting is demanded.
ͶFeatures
1) ! WLCSP ultra-compact package (1.6 mm x 1.6 mm x 0.75 mm)
2) ! Improved noise characteristics over BH768xxFVM series
3) ! Four video driver amplifier gains in lineup: 6 dB, 9 dB, 12 dB, 16.5 dB
4) Large output video driver of maximum output voltage 5.2 Vpp. Ample operation margin for supporting even low
voltage operation
5) Output coupling capacitor not needed, contributing to compact design
6) Built-in standby function and circuit current of 0 μA (typ) at standby
7) Clear image playback made possible by built-in 8
8) Due to use of bias input format, supports not only video signals but also chroma signals and RGB signals
9) Due to built-in output pin shunt switch, video output pin can be used as video input pin (BH76706GU)

Fig.3 Fig.4
For an amplifier operated from a single power supply (single-supply), since the operating point has a potential of
approximately 1/2 Vcc, a coupling capacitor is required for preventing direct current in the output. Moreover, since the
load resistance is 150 (75 + 75 ) 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.

3) Configuration of BH769xxGU and BH76706GU
As shown in Fig. 6, a BH769xxGU or BH76706GU is a dual-supply amplifier and charge pump circuit integrated in one IC.
Accordingly, while there is +3 V single-supply operation, since a dual-supply operation amplifier is used, an output
coupling capacitor is not needed.

4) Input pin format and sag characteristic
While a BH769xxGU or BH76706GU is a low voltage operation video driver, since it has a large dynamic range of
approximately 5.2 Vpp, a resistance termination method that is compatible regardless of signal form (termination by 150
k) is used, and not a clamp method that is an input method exclusively for video signals.
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 k, 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)

We are confident in recommending the above application circuit example, but we ask that
you carefully check not just the static characteristics but also transient characteristics of this
circuit before using it.
ͶCaution on use
1.! 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 F, 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 F, B characteristics, 6.3 V or higher maximum voltage)
5. The HPF consists of input coupling capacitor C3 and 150 kȍ 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/(2ԠC3150kԈ) (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 ȍ) in the VCC line to improve the power supply's ripple
effects. Although inserting a 10 ȍ 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. (See Figures 12 to 14.)

Ͷ Performing separate electrostatic damage countermeasures
When adding an externally attached electrostatic countermeasure element to the output pin, connect a varistor in the
position shown in Fig. 59 (if connected directly to the output pin, the IC could oscillate depending on the capacity of the
varistor). For this IC, since the output waveform is GND-referenced and swings positive and negative, a normal Zener
diode cannot be used.
