Description 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 A 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. Features 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 A (typ) at standby th 7) Clear image playback made possible by built-in 8 -order 4.5 MHz LPF 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) Applications Mobile phone, digital still camera, digital video camera, hand-held game, portable media player Line up matrix Product Name BH76906GU BH76909GU BH76912GU BH76916GU BH76706GU Absolute Maximum Ratings Parameter Supply voltage Power dissipation Operating temperature range Storage temperature range (Ta = 25 C) Symbol Vcc Pd Topr Tstg Rating 3.55 580 -40+85 -55+125 Unit V mW Video Driver Amplifier Gain 6dB 9dB 12dB 16.5dB 6dB Recommended Input Level 1Vpp 0.7Vpp 0.5Vpp 0.3Vpp 1Vpp Video Output Pin Shunt Function

Description of Operation 1) Principles of output coupling capacitorless video drivers Single-supply amplifier VCC Output capacitor required since DC voltage is occurring at output pin 75 1000F 75 -VCC
Dual-supply amplifier VCC Output capacitor not required since DC voltage does not occur at output pin 75 75
1/2 VCC bias 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 F 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. VCC 1F 150k

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.
Caution 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. Capacitors to use In view of the temperature characteristics, etc., we recommend a ceramic capacitor with B characteristics. 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 F, B characteristic, 6.3 V or higher maximum voltage)
2. 3.
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 k 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/(2xC3x150k) (Recommended C3: 1.0 F, 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 ) in the VCC line to improve the power supply's ripple effects. Although inserting a 10 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.)

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.
