DESCRIPTION
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.
FEATURES
Frequency band : RGB
Input lev el
Only t he G channel is prov ided with sy nc-on v ideo output.
The TTL f ormat is adopted f or HV output.
