PPS Out and Event Inputs
The PPSout pin of header J500 is directly connected to the PPSOut pin of the AsteRx-m2a
(see section 2.5.1). The PPS level is 3.3V.
The EVENTA and EVENTB pins of J500 are connected to the EventA and EventB pins of the
AsteRx-m2a through a buffer. The voltage level at the header pins must be between -
0.5V and +6V. These pins are pulled-down by a 100kOhm resistor. See section 2.7 for
more details.
