1 Introduction
The REFGEN is an analogue and digital black generator that will output both
an analogue and serial digital reference. The REFGEN may be operated in a
stand-alone free-running mode or when given an analogue input, an output
that is locked to the input but with up to a two field delay. A choice of a blue or
black output may also be selected.

The serial digital output has virtually no output jitter both when used with a
stable analogue reference and when used without a reference. The minimum
delay between the input reference and output is only 2
µ
s.
The main features are as follows:
•
Free running or timed to analogue input
•
Selectable black or blue output
•
Up to four simultaneous Serial Digital and four Composite outputs
•
Output timing up to two field’s adjustment from analogue reference input.
•
50 ppm free running accuracy
•
Flexible control
REFGEN is a 100mm x 266mm module that will fit in all the standard frames
and can be integrated with any boards from the company’s full product range.
Free running and synchroniser/delay modes
The REFGEN has two modes of operation, free running and synchroniser/delay.
