The M52755FP is a semiconductor integrated circuit for the
RGBHV interface. The device features switching signals input from
two types of image sources and outputting the signals to the CRT
display, etc. Synchronous signals, meeting a frequency band of
10kHz to 200kHz, are output at TTL. The frequency band of video
signals is 250MHz, acquiring high-resolution images, and are
optimum as an interface IC with high-resolution CRT display and
various new media.

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 capitance of output terminal as small as possible.
⋅ Set the capitance 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.
