●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 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.

●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 μA (typ) at standby

7) Clear image playback made possible by built-in 8^th-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

Fig.3

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

kꢀ) 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 kꢀ, 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 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 kꢀ 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 ꢀ) 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.

2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor

products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate

safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which

a failure or malfunction of our Products may cause. The following are examples of safety measures:

[a] Installation of protection circuits or other protective devices to improve system safety

[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure

3. Our Products are designed and manufactured for use under standard conditions and not under any special or

extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way

responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any

special or extraordinary environments or conditions. If you intend to use our Products under any special or

extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of

product performance, reliability, etc, prior to use, must be necessary:

[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents

[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust

[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,

H2S, NH3, SO2, and NO2

[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves

[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items

[f] Sealing or coating our Products with resin or other coating materials

[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of

flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning

residue after soldering

[h] Use of the Products in places subject to dew condensation

4. The Products are not subject to radiation-proof design.

5. Please verify and confirm characteristics of the final or mounted products in using the Products.

6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,

confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power

exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect

product performance and reliability.

7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual

ambient temperature.

8. Confirm that operation temperature is within the specified range described in the product specification.

9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in

this document.

Precaution for Mounting / Circuit board design

1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product

performance and reliability.

2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the

ROHM representative in advance.

For details, please refer to ROHM Mounting specification
