CXA1616N/S
Sync Discriminator for CRT Displays
Description
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.
CXA1616N
24 pin SSOP (Plastic)
CXA1616S
22 pin SDIP (Plastic)
Features
• Output of synchronous signal polarity information is
obtainable
• Supported polarities and amplitudes of input sig-
nals are as follows:
— V. separate sync
(positive/negative polarity, 1 to 5Vp-p
For capacitor input 1.5 to 5Vp-p)
— H. separate sync
(positive/negative polarity, 1 to 5Vp-p)
— Composite sync
(positive/negative polarity, 1 to 5Vp-p)
— Sync-on video
(negative polarity sync level: 0.2 to 0.6Vp-p,
picture level: 0 to 2.1Vp-p)
