CXA2016S
Sync Identification for CRT Display
Description
The CXA2016S is used for sync signal
identification and waveform shaping in the CRT
computers display for multi-scan system. There are
three types of sync input signals for identification:
separate sync, composite sync, and sync on video
signals.
22 pin SDIP (Plastic)
Features
• Power save function available (5 V power supply)
• Clamp pulse output position selectable among sync
interval, back porch interval, and AUTO.
• Polarity information of sync signals is output.
• Polarity and amplitude of input signals:
Polarity
Amplitude (Vp-p)
V. separate sync: Positive/Negative 1 to 5
H. separate sync: Positive/Negative 1 to 5
Composite sync: Positive/Negative 1 to 5
Sync on video:
