XIP - 3901
User Manual
The XIP - 3901 has an integrated frame sync that supports synchronous and asynchronous
SDI input signals. The input signals will be synchronized and realigned to either the URS or
External Reference.
The frame sync behaves like a frame buffer. It also supports frame skips/repeats in the case
of an asynchronous SDI input. When an input error occurs, it freezes to the last valid
field/frame.
