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.
