Compact Video Driver Series for DSCs and Portable Devices Compact, Low Current Consumption Single Output Video Drivers BH76106HFV, BH76109HFV, BH76112HFV, BH76206HFV No. 09064EAT03 ●Description This video amplifier with built-in LPF uses a full output swing type output stage to make low voltage operation at Vcc = 2.6V possible. In addition to advantages such as a tiny package and low power consumption, bands of the built-in LPF provide for 4.5 MHz products for DSC and other portable equipment and 6 MHz products for equipment such as DVD. Moreover, since it also can be used at Vcc = 5 V, it is suited not only to portable equipment but also to equipment for stationary use. ●Features 1) Wide operating voltage range: Vcc = 2.6 V~5.5 V th 2) Built-in 8 order LPF 3) Built-in sync-tip clamp circuit 4) Compact HVSOF6 package (3.0 mm × 1.6 mm × 0.75 mm) 5) Built-in standby function Standby current: 0 μA (typ.) 6) Selectable gain 6dB (BH76106HFV, BH76206HFV), 9dB (BH76109HFV), 12dB (BH76112HFV) 7) Selectable filter characteristics f = 4.5 MHz (BH761xxHFV), f = 6.0 MHz (BH76206HFV) ●Applications Mobile phone, DSC, DVC, DVD, and other ●Line up matrix Product Name BH76106HFV BH76109HFV BH76112HFV BH76206HFV ●Absolute Maximum Ratings Parameter Amplifier Gain (dB) 6 9 12 6 LPF Frequency (MHz) 4.5 4.5 4.5 6.0 Symbol Rating Unit Power Supply Voltage Vcc 7 V Power Dissipation Pd 410 ＊ mW Operating Temperature Topr -40～+85 ℃ Range Storage Temperature Tstg -55～+125 ℃ Range ＊ When mounted on a 70 mm×70 mm×1.6 mm ROHM standard board, reduce by 4.1mW/℃ above Ta=+25℃ ●Operating Range Parameter Symbol Min.

(2) Although we are confident recommending the application circuit example, carefully check the characteristics further in conjunction with its use. If using it after modifying externally attached component constants, try to determine adequate margins by including not just static characteristics but also transient characteristics to take into account variations in externally attached components and the ROHM LSI. (3) Absolute maximum ratings If absolute maximum ratings such as applied voltage and operating temperature range are exceeded, the IC may be damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you are considering circumstances in which an absolute maximum rating would be exceeded, implement physical safety measures such as fuses and investigate ways of not applying conditions exceeding absolute maximum ratings to the LSI. (4) GND potential Even if the voltage of the GND pin is left in an operating state, make it the minimum voltage. Actually confirm that the voltage of each pin does not become a lower voltage than the GND pin, including for transient phenomena. (5) Thermal design Perform thermal design in which there are adequate margins by taking into account the allowable dissipation under conditions of actual use. (6) Shorts between pins and mounting errors When mounting the LSI on a board, be careful of the direction of the LSI and of misalignment. If mounted badly and current is passed though it, the LSI may be damaged. The LSI also may be damaged if shorted by a foreign substance getting in between LSI pins, between a pin and the power supply, or between a pin and GND. (7) Operation in a strong electromagnetic field Since the LSI could malfunction if used in a strong electromagnetic field, evaluate this carefully. (8) Input termination resistor Since there is a risk of oscillation at low temperatures (approximately -60 °C) if the termination resistor of the input pin is made high impedance, set it to no more than 700 Ω. 0.1μ DAC Vin Fig.2 If the termination resistor of the input pin is greater than 700 Ω, connect it as shown in the figure below. 0.1μ DAC 1kΩ Vin DAC 1kΩ 470Ω Vin 0.1μ Insert an emitter follower to lower the output impedance.

Since adding a voltage greater than Vcc at the standby pin turns a protective diode ON, make this at most Vcc+0.2 V (no greater than Vcc+VF). (See Fig. 4) Applying a voltage to the standby pin when the voltage Vcc is not being applied also turns the protective diode ON, so do not apply a voltage.

Noise also does not occur when toggling the switch. Fig.6 Standby Response Characteristic ※In relation to IC shutdown, this is after approximately 2 μs. (10) Input coupling capacitor Making the input coupling capacitor a value less than 0.1 μF (the recommended value) increases SAG. Determine the capacitance of the input capacitor used after taking into consideration the relationship of SAG to input coupling capacitor.

When input coupling capacitor (②) is 1 μF Time until output voltage stabilizes (③): 2.03 s (11) SAG correction In order to make the SAG of the video signal as small as possible, we recommend the values of the application circuit diagram for output coupling capacitor capacitance. If reducing capacitance due to the demands of miniaturization or the like, check the SAG characteristic for an alternating black and white bounce signal *1, Hbar signal *2, or other signal for which a SAG effect readily occurs and use a capacitance that satisfies the demands of the set being used. As a reference, try the combinations shown below when reducing capacitance. As the capacitance of the VOUT capacitor is made smaller, SAG becomes greater. *1,*2: TG-7 U705 unit or other Vsag Capacitor (C1) VOUT Capacitor (C2) 33μF 68μF 33μF 47μF 33μF 33μF (12) Using after removing output coupling capacitor An application circuit that is an example of use after removing the output coupling capacitor is shown in the figure below.

However, since direct current will flow in a set connected on the opposite side due to eliminating the output coupling capacitor, pay close attention to the specifications of what is connected in conjunction with using it. Moreover, characteristics such as circuit current, differential gain, and differential phase differ as shown below.

They are not guaranteed values. (13) Output dynamic range The output dynamic range depends on the power supply voltage. Be careful when using the LSI at low voltage. The relationship of dynamic range to Vcc is shown in Fig. 19. www.rohm.com © 2009 ROHM Co., Ltd.

(15) Metal part of back of package The metal part of the back of the package of this IC also serves as a heat sink. Since it is connected to the GND of the IC, when mounting the IC, connect it to GND or make it NC. Moreover, since there is a risk of shorting, avoid passing a wire other than a GND under the IC.
