Mitsubishi M52347FP Datasheet
MITSUBISHI ICs (Monitor)
M52347SP/FP
SYNC SIGNAL PROCESSOR
DESCRIPTION
The M52347 automatically selects three types of synchronous
signals containing separate sync (positive and negative polarities of
0.5 to 2.5 V
0.5 to 2.5 V
), composite sync (positive and negative polarities of
P-P
P-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 / .
Equipped with CLAMP SW that enables switching the clamp
•
14 15
pulse output position.
APPLICATION
Display monitor
