Frequently Asked Questions
What Multi-PIP capabilities are available on this controller?
The device supports internal simple Multi-PIP (3 × 3) or (4 × 4) conversion, and full performance using an external PIP module.
How does the SAA4952WP connect to a microcontroller?
It connects via an 8-bit LIMERIC data bus (SAA4945H), receiving commands through the I^2C bus.
What types of scan conversions are supported?
It supports progressive scan at 50 Hz/1250 lines (or 60 Hz/1050 lines), as well as interlaced or standard 50 Hz/625 lines modes.
