C2C-Link Electrical Specification

Trigger delay

Propagation delay of the trigger signal from the master device to a slave device. This delay is composed of the propagation delay inside electronic devices (FPGA, adapter...) and interconnection cables.

For cables, the delay is proportional to the cable length, typically: 5 ns/m.

Trigger delay skew

Dispersion of the trigger delay values across all the devices belonging to a C2C-Link.

Trigger delay jitter

Variation of the trigger delay depending on external factors such as temperature, signal noise...

Trigger rate

Rate of occurrence of repetitive trigger events. The reciprocal value (1/Trigger rate) is the minimum time interval required between consecutive triggers.

Parameter Min. Typ. Max. Units
Trigger delay jitter     5 ns
Trigger rate 0   2.5 MHz
Parameter Min. Typ. Max. Units
Cable connectors count (including 1636 adapter if any) 2   8 -
Cable length –   1.2 m
Trigger delay jitter 5   10 ns
Trigger rate 0   2.5 MHz

The following specification targets applications where the highest trigger rate is required:

Parameter Min. Typ. Max. Units
1636 adapters count 2   10 -
Adapter-to-adapter LAN cable length 0.3   100 m
Cumulated adapter-to-adapter LAN cable length 0.3   100 m
Trigger delay jitter 10 20 40 ns
Trigger rate 0   2.5 MHz

The following specification targets applications where the longest reachable distance is required:

Parameter Min. Typ. Max. Units
1636 adapters count 2   32 -
Adapter-to-adapter cable length 0.3   1200 m
Cumulated adapter-to-adapter cable length 0.3   1200 m
Trigger delay jitter     1 µs
Trigger rate 0   200 kHz

The maximum trigger rate specification can be extrapolated for intermediate distances between 100 m and 1200 m assuming that the length x frequency product is constant: in this case 250 [m. MHz].
