2.9.3 Agile Mixed Signaling (AMS) Connector, J2
The XADC header provides analog connectivity for analog reference designs, including AMS
daughter cards like Xilinx’s AMS Evaluation Card.
The analog header is placed close to the LPC FMC header as shown. Both analog and digital IO
can be easily supported for a plug in card. This allows the analog header to be easily connected
to the FMC card using a short ribbon cable as shown. The analog header can also be used
“stand alone” to support the connection of external analog signals.
The pin out has been chosen to provide tightly coupled differential analog pairs on the ribbon
cable and to also provide AGND isolation between channels. The plug in cards which will
facilitate a number of reference designs have not yet been designed so this pin out must provide
a reasonable degree of freedom while also keeping resource requirements as minimal as
possible.
The ZedBoard AMS header is comparable with similar connectors on the Xilinx KC705 and
ZC702 boards. Any AMS plug-in cards built for those boards should be compatible with
ZedBoard as well.
