DESCRIPTION
PIN CONFIGURATION(TOP VIEW)
The M52758 is a semiconductor integrated circuit f or the RGBHV
interf ace. The dev ice f eatures switching signals input f rom two
ty pes of image and outputting them to CRT display etc.
Sy nchronous signal meeting the f requency band of 10 kHz to
200 kHz are output at TTL. The f requency band of v ideo signals
is 250MHz, acquiring high-resolution images,and are optimum as
an interf ace IC with high-resolution CRT display and v arious new
media.

Note how to use this IC (Pin No is FP)
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.1. It is possible to
reduce rise time by insert the resister between Vcc line and H, V output
Pin, but set the value of resister in order that the current is under 7.5 mA.
Setting the value of R is more than 2K as shown in Fig.1 .

6. Switch (Pin 19) 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 to 0.5V : Signal output from input 1
2 to 5V : Signal output from input 2
It is not allowable to set voltage higher than Vcc.

order that the current is under 10mA. Setting the value of R is more than

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 resister and output pin is as short as possible when
insert a output pull-down resister.
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(if possible the separated power-source will be
better).
It will reduce the oscillation when add a resister that is tens of ohms
between output pin and next stage.
Assign an area as large as possible for grounding.
