3.3.1 Reclocker mode

The reclocker can be set to reclock or bypass from DIP#1 and DIP#4 or from GYDA.

When reclocker is set to reclock mode jitter from signal is removed. Accepted bitrates is 270,
1483.5, 1485, 2967 and 2970Mbps.

When reclocker is set to bypass the converter accepts all bitrates between 2 to 2970Mbps.
Note that in this mode the jitter is not removed and this can cause problems for equipment
following the converter.

3.3.1.1 Transparency
This converter only looks at the bitrates and not the content. This means that any signal with
correct bitrates is converted. The product is transparent to data in the ancillary space like
embedded audio.
