CXA1616N/S
Sync Discriminator for CRT Displays
Description
CXA1616N
24 pin SSOP (Plastic)
CXA1616S
The CXA1616N/S automatically selects one of three
types of sync signals – separate sync, composite sync,
or sync-on video – to shape the waveform. It is ideally
suited as a synchronous signal processor for auto
tracking type displays.
22 pin SDIP (Plastic)
