7 References and Output Timing
7.1 References
M-VIVID outputs can be locked to a PTP clock, an analogue tri-level or Black & Burst sync or
the SDI input if present and selected as the input protocol. If the chosen reference sources
are absent at power up, the outputs will freerun to an internally generated clock.
All outputs are locked to the same reference clock. It is not possible to lock different outputs
to different clocks.
Inputs are not required to be the same frame rate as the chosen reference. It is possible, for
example, to input 59.94Hz video locked to a 50Hz reference. However, frames will be
dropped and repeated as necessary when cross-locking frame rates in order to maintain a
valid output.
