WIDE BAND ANALOG SWITCH
DESCRIPTION
The M52757FP is a semiconductor integrated circuit for
the RGB interface. The device features switching signals
input from two types of image sources and outputting the
signals to the CRT display,etc. The frequency band of
video signals is 250MHz, acquiring high-resolution
images, and are optimum as an interface IC with highresolution CRT display and various new media.
It includes Sync-separator, Video-signal-detector, and
Sync-on G detector (SOG-DET.).
FEATURES
• Frequency band width : R.G.B ...................250MHz
• Input level : R.G.B...............................0.7Vp-p (Typ.)
• Video signal-detector
Responsive frequency............................... ~50MHz
Input level............................................0.7Vpp (Typ.)
Detected level......................................150mV (Typ.)
(Measure bottom to DET.level)
• Only the G channel is proveded with buffer video output.
• It is possible to save the consumption current by
stopping current supply to Pin 2,4,6,20,24,30,33,35
because SOG-DET can be operated with only Vcc5
(Pin 15) as power save mode.
• Include Sync Separation,Video signal detector, and
Sync-on G detector.
