7.6 PPS Out and Event Inputs
The PPSout pin of header J500 (2x8 2mm-pitch DIL) is connected to the PPSO pin of the
mosaic module through a 1.8V to 3.3V level shifter. The PPS level at the header is 3.3V.
The EVENTA and EVENTB pins of J500 are connected to the EventA and EventB pins of the
mosaic through a level shifter to 1.8V. The voltage level at the header pins must be
between -0.5V and +6V. These pins are pulled-down by a 100kOhm resistor.
7.7 Ethernet
The DevKit supports 10/100 Base-T Ethernet. It is not possible to power the DevKit
through the Ethernet connector.
The development kit is compliant with EU EMC standards (EN303413) provided the
Ethernet interface is disabled (with the
setEthernetMode user command). When the
Ethernet interface is enabled, harmonics from the RMII interface slightly violate this
regulation, as they radiate via the 60-pins board-to-board connector. It is up to the
integrator to take the necessary precautions to avoid EMC violations in this case (e.g. use
shielded box).
7.8 USB Dev
That connector can be attached to a PC to power the DevKit and to communicate with the
module over its USB port.
