The AT-XMC/PMC-GPS is a slave mezzanine Card which provides x1 Lane PCI-Express interface or 32 bit PCI interface with the host system. It provides interface to host with different types of IO signals for the avionics domain user interactions. The board has an onboard clock, which is kept in sync to either an external time code input or time provided by GPS satellites. Several timing functions are derived from the on-board clock including a programmable periodic pulse rate output ("Heartbeat"), a programmable start/stop output ("Match"), a selectable frequency output ("Oscillator Out", 1 kHz, 1, 5, or 10 MHz) & a time-stamping input ("Time-Tag�).

An onboard IRIG-B time encoder & decoder allow users to accurately synchronize single or multiple modules to a common time source. The card has implemented all its Discrete IO logic in the FPGA. An Octal UART is used to implement serial port functionality. The Card consists of 8 ports of which 4 ports provide full functionality & other 4 provide half control. When configured for RS232 mode a port provides the full set of data & modem control lines. It can also be configured in RS485/RS422 mode. GPS functionality is provided by a receiver built into the antenna housing & communicates to the board via (RS-422) interface.

The AT-XMC/PMC-GPS software includes Drivers & APIs which come with a powerful set of library functions to access the entire SPT functionality. The drivers are designed in a modular fashion consisting of component functions & application functions. The user�s test program can be developed with few calls to the driver by using the set of application functions provided. All data bus functionality is supported by our advanced API (Application Programming Interface). Driver & high-level API libraries for Windows XP, Windows 7 & Linux are available.
