The Utah-400
DS10-DS12 represent a 3-bit data rate indication
These LEDs change at about a 1 second rate, giving you status of all of the re-clockers in
about seven seconds.
If the onboard MPU cannot access the re-clocker chips to control them, DS10-DS17 will be set
in a ‘55’ pattern to indicate a communication problem.
Control Description
The Multi-Rate card has a single dipswitch, SW1, which enables or disables each of the 8
reclockers. When the dipswitch for a given output is set to the ‘Reclock’ position, the re-clocker
will continually hunt for one of the following rates -- 270 Mb/Sec. (SMPTE 259M), 360 Mb/Sec.
(SMPTE 259 Wide Screen), 540 Mb/Sec. (SMPTE 344) or 1.485 Gb/Sec. (SMPTE292). When
it finds one of these data rates, it will lock to it and re-time the data to reduce jitter. If it loses
lock, it will continue the process of hunting for the next data rate.
If the switch is set to ‘Bypass’, the re-clocker will not re-time the data, it will simply pass it from
it’s input to it’s output. This is the preferred setting for any rate other than one of the ones listed
above.
