DESCRIPTION
The M52347 automatically selects three types of synchronous
signals containing separate sync (positive and negative polarities of
0.5 to 2.5 VP-P), composite sync (positive and negative polarities of
0.5 to 2.5 VP-P) and sync-on-video (sync negative polarity), and
performs waveform shaping. The IC is optimum to synchronous
signal processing for multi-scan type display monitor.
FEATURES
• Low power consumption with supply voltage of 5V
• Capable of obtaining output information on whether to input syn-
chronous signal, and on polarity
• Output of clamp pulse
• Equipped with V TIME GATE SW that enables selecting whether
or not VD portion pulse is output from pin 14 / 15 .
• Equipped with CLAMP SW that enables switching the clamp
pulse output position.
