Introduction
ADDEC-210 12-bit Synchronising Decoder
The ADDEC-210 is a 100mm x 266mm module that fits in Crystal Vision’s four standard
frame sizes. 24 modules fit in 4U, 12 modules fit in 2U, six in 1U or two in a desktop box.
There are a range of rear connector modules available for the ADDEC-210 which allow
the system builder great flexibility in frame configuration.
1.1 Operating modes
Synchronisation and Delay Modes
There are two modes of operation - Synchronisation and Delay.
In Synchronisation Mode the unit takes its timing from the analogue external reference
and will automatically synchronise sources between zero and two fields. Synchronisation
Mode is ideal for external sources that are not timed to station references such as satellite
or remote contribution feeds.
In Delay Mode, timing is derived only from the analogue input. Typical applications are
where a source passes through a processor such as a DVE, Chroma keyer or standards
converter where the delay can be a few microseconds, multiple lines or up to two fields.
