ASYNCHRONOUS TIMING
Asynchronous system timing consists of two signals. The first, derived from the reference video input’s
A sync stripper derives the vertical retrace pulse and passes it on to a microprocessor for processing into strobe and
An oscillator provides the master clock for the entire system. When used on the NV3128, this oscillator free runs.
PARTITIONING

On the newer Universal Control module, partitioning is set up using UniDiag and stored in memory.
