●Description
The BA7657S, 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 BA7657S and BA7657F feature a separation (BUNRI) circuit for the synchronization signal that
2
is superposed on the G signal, while the BH7659FS features an on-chip switch for I C bus signals (SDA and SCL).
These ICs can be used to simplify the input block configuration in advanced display devices.
●Features

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.

●Description of operations
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
2
SDA and SDC signals are switched via an I C bus to handle two channels of HD and VD synchronization signals, and to
exchange information bidirectionally between a computer and a monitor.
2
The switching circuits used by this IC handle are configured as CMOS analog switches in order to handle I C BUS
signals and to transmit input and output signals bidirectionally. (ON resistance: Ron 200 Ω typ.)

●Cautions on use (1/2)
[BA7657S/F, 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.
