M52348SP
WIDE FREQUENCY BAND ANALOG SWITCH
DESCRIPTION
The M52348SP is an semiconductor IC for RGBHV interface that
switches signals input from two types of image source and outputs
them to CRT display etc. The synchronous signal meets the
frequency band of 10 kHz to 200 kHz and is output with TTL. The
IC adopts 250 MHz for the frequency band width of video signal,
providing high resolution images. It is optimum as an IC for
interface with various types of new media including high resolution
CRT.
FEATURES
• Frequency band : RGB..................................................250MHz
