BA7657F,BH7659FS

●Description

The BA7657F, and BH7659FS are ICs that have been developed for use in PC monitors, HDTVs (high definition televisions),

and other high-resolution display devices. In addition to their wide-range switching circuits for RGB signals, HD signals,

and VD signals, the A7657F feature a separation (BUNRI) circuit for the synchronization signal that is superposed on the

G signal, while the BH7659FS features an on-chip switch for I²C bus signals (SDA and SCL). These ICs can be used to

simplify the input block configuration in advanced display devices.

●Features

1) Operates on 5 V single power supply.

2) Built-in wide-range RGB signal switches.

(BA7657F :fc = 230 MHz)

(BH7659FS:fc = 250 MHz)

3) Built-in switching circuit for HD signal and VD signal.

4) Built-in separation (BUNRI) circuit for synchronization signal superposed on G signal. (BA7657F)

5) Built-in switch for I²C bus signals (SDA and SCL). (BH7659FS)

6) Built-in power saving function. (BH7659FS)

●Applications

PC monitors, Plasma displays, LCD monitors, and Other devices that use wide-range RGB signal switching.

●Description of operations

○BA7657F

1) Analog SW block

Two channels of RGB signals can be switched. IN1 can be selected when high-level voltage is applied to the CTL pin,

and IN2 can be selected when low level voltage is applied.

2) Digital SW block

This block switches between two channels of HD and VD ynchronization signals. HD and VD synchronization signals are

output for IN1 when high-level voltage is applied to the CTL pin, and these signals are output for IN2 when a low-level

voltage is applied to the CTL pin.

3) Synchronization signal separation block

This block separates composite signals (Sync on Green) and synchronization signals and outputs positive-electrode

composite synchronization signals. When an HD signal is being input, the synchronization signal detector operates and

stops the synchronization signal separation circuit. A low-level output voltage is used for output. The time at which the

synchronization signal separation circuit will be stopped can be set using external time constants for the circuit detection

pin.

○BH7659FS

1) Analog SW block

R, G, and B chroma signals are switched in two channels. INA is selected by applying a high-level voltage to the CTL pin,

and INB is selected by applying a low-level voltage. When the power save pin (pin 8) is set to high level, the current to

the SW block's output transistors is reduced to lower the circuit current. Even during low power mode, signal switching

can be performed normally as long as there is no drop in frequency characteristics.

2) CMOS analog SW block

SDA and SDC signals are switched via an I²C bus to handle two channels of HD and VD synchronization signals, and to

exchange information bidirectional between a computer and a monitor. The switching circuits used by this IC handle are

configured as CMOS analog switches in order to handle I²C BUS signals and to transmit input and output signals

bidirectional. (ON resistance: Ron 200 Ω typ.)

●Notes for use

○BA7657F, BH7659FS

1) Numbers and data in entries are representative design values and are not guaranteed values of the items.

2) Although we are confident in recommending the sample application circuits, carefully check their characteristics further

when using them. When modifying externally attached component constants before use, determine them so that they

have sufficient margins by taking into account variations in externally attached components and the Rohm LSI, not only

for static characteristics but also including transient characteristics.

3) Absolute maximum ratings

If applied voltage, operating temperature range, or other absolute maximum ratings are exceeded, the LSI may be

damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you think of a case in

which absolute maximum ratings are exceeded, enforce fuses or other physical safety measures and investigate how

not to apply the conditions under which absolute maximum ratings are exceeded to the LSI.

4) GND potential

Make the GND pin voltage such that it is the lowest voltage even when operating below it. Actually confirm that the

voltage of each pin does not become a lower voltage than the GND pin, including transient phenomena.

5) Thermal design

Perform thermal design in which there are adequate margins by taking into account the allowable power dissipation in

actual states of use.

6) Shorts between pins and misinstallation

When mounting the LSI on a board, pay adequate attention to orientation and placement discrepancies of the LSI. If it is

misinstalled and the power is turned on, the LSI may be damaged. It also may be damaged if it is shorted by a foreign

substance coming between pins of the LSI or between a pin and a power supply or a pin and a GND.

7) Operation in strong magnetic fields

Adequately evaluate use in a strong magnetic field, since there is a possibility of malfunction.

8) External resistance for analog SW block

The frequency characteristics of analog switches vary according to the output load capacity. Set an external resistance

value of R0 to keep frequency characteristics as flat as possible.

9) Polarity of input coupling capacitor

When this IC is switched, variation is approximately 3.7 V when the input pin's DC voltage has been selected, but is 0 V

when the input pin's DC voltage has not been selected. Therefore, the input coupling capacitor's polarity should be set

so as to avoid applying a reverse voltage to capacitors, whether the input pin's DC voltage has been selected or not.

10) High-frequency characteristics of input coupling capacitor

Since this IC handles signals at very high frequencies, when using an electrolytic capacitor as a coupling capacitor for

input, be sure to insert high-frequency oriented ceramic capacitors (approximately 0.01 µF) in parallel.

11) Layout of target board

Since this IC handles signals at very high frequencies, be sure to insert the power supply pin's decoupling capacitor

close to the IC's power supply pin. Also, use as large a GND pattern as possible.

12) Switching speed

Since this IC changes the DC voltage of input pins when switching, some time is required for switching. The amount of

switching time can be determined by time constants that are in turn determined by the capacity of the coupling capacitor

connected to the input pin, and the IC's internal input resistance. When using the recommended input coupling capacitor

whose capacitance is 47 µF, the switching time is approximately 0.5 seconds.

13) External resistance for analog SW block

The frequency characteristics of analog switches vary according to the output load capacity. Set an external resistance

value of R0 to keep frequency characteristics as flat as possible.

14) Polarity of input coupling capacitor

When this IC is switched, variation is approximately 3.5 V when the input pin's DC voltage has been selected, but is 0 V

when the input pin's DC voltage has not been selected. Therefore, the input coupling capacitor's polarity should be set

so as to avoid applying a reverse voltage to capacitors, whether the input pin's DC voltage has been selected or not.

15) High frequency characteristics of input coupling capacitor

Since this IC handles signals at very high frequencies, when using an electrolytic capacitor as a coupling capacitor for

input, be sure to insert high-frequency oriented ceramic capacitors (approximately 0.01 µF) in parallel.

16) Layout of target board

Since this IC handles signals at very high frequencies, be sure to insert the power supply pin's decoupling capacitor

close to the IC's power supply pin. Also, use as large a GND pattern as possible.
