Overview: |
|
|
This AT-XMC/PMC-DIO is a slave mezzanine module, provides x1 Lane PCI-Express interface or 32 bit PCI interface with the host system. It provides interface to host with different types of input and output signals for the avionics domain user interactions.
The XMC/PMC Discrete I/O boards are designed to provide users with a high degree of reliability and flexibility to meet input-output requirements. They are ideally suited for stringent military and airborne applications.

Hardware:
The AT-XMC/PMC-DIO has implemented all its Discrete IO logic in the FPGA. All discrete inputs and outputs are accessed through registers implemented inside FPGA. Discrete outputs can be used to switch the +27V/GND/OPEN type loads.
The AT-XMC/PMC-DIO card provides a total of 40 nos of discrete IO interface to the PCI/PCIe bus. Twelve nos are of +27V/OPEN type or Casing break type inputs, eight nos are of Open/GND type inputs and an equal number of respective outputs. The card also provides for 4 pairs of differential outputs and inputs each, but the number of such pairs available is dependent on the type of bus interface. All 4 pairs of differential IO are available in XMC mode and only 2 pairs in PMC mode.
The AT-XMC/PMC-DIO provides I/O interface through front panel mounted 68-pin PCB mount Right angled VHDCI receptacle connector or though rear XMC user I/O connector J16 or PMC I/O connector JN4 for accessing the I/O through back plane. On-chip Timers are used for scheduled status reading of discrete inputs or drive of discrete outputs.
The source for all the power necessary in the card is drawn from the PMC/XMC connector. The Card needs 3.3V, 5V, +12V, 1.2V and 1.5V voltages for its operation. 5V is generated using an on board dc-to-dc converter from 12V input of XMC connector. The 1.2V and 1.5V voltages are generated using adjustable LDO from 3.3V of XMC/PMC connector.
