M52756SP

WIDE BAND ANALOG SWITCH

Note how to use this IC

1. R, G, B input signal is 0.7Vp-p of standard video signal.

2. H, V input is 2.0V(minimum) TTL type.

3. Input signal with sufficient low impedance to input terminal.

4. The terminal of H, V output pin are shown as Fig.4. It is possible to

reduce rise time by insert the resistor between Vcc line and H, V output

Pin, but set the value of resistor in order that the current is under 7.5 mA.

Setting the value of R is more than 2kΩ as shown in Fig.4 .

5. Switch (Pin 15) can be changed when this terminal is GND or OPEN

When GND : Signal output from input 1

When OPEN : Signal output from input 2

When the switch is being used as Fig.5

0 ~ 0.5V : Signal output from input 1

2 ~ 5 V : Signal output from input 2

It is not allowable to set voltage higher than Vcc.

Notice of making printed circuit board.

Please notice following as shown below. It will maybe cause something oscillation because of the

P.C.B. layout of the wide band analog switch.

• The distance between resistor and output pin is as short as possible.

• The capacitance of output terminal as small as possible.

• Set the capacitance between Vcc and GND near the pins if possible.

• Using stable power-source.

The separated 12V-power-source (if possible the separated 5V-power-source will be better).

• Assign an area as large as possible for grounding.

• Pay attention to leak of signaling from the output.
