M52347SP/FP
SYNC SIGNAL PROCESSOR
1
DESCRIPTION
The M52347 automatically selects three types of synchronous
signals containing separate sync (positive and negative polarities of
0.5 to 2.5 V
P-P
), composite sync (positive and negative polarities of
0.5 to 2.5 V
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
pulse output position.
APPLICATION
Display monitor
RECOMMENDED OPERATING CONDITION
Supply voltage range..............................................Vcc=4.5 to 5.5V
Rated Supply voltage............................................................Vcc=5V
