Universal CompactPCI® Serial FPGA I / O Interface Card

Get the highest adaptability via SA-Adapter™ PHYs and FPGA.

While COM ports are still included in the relevant CPU chipsets at the moment, they are only partly led to the front panels of single-board computers for CompactPCI® Serial (or CompactPCI PlusIO). Besides, the number of the available UARTs might sometimes be insufficient and fieldbus interfaces are not part of the standard product range of CPU manufacturers anyway.

The G215 can help to complete such a system. By default, two UARTs, two CAN interfaces and an 8-channel binary I / O interface are accessible at the front panel of the G215.

The physical layer of the highly versatile interface board can be implemented individually for each channel via SA-Adapters™. Two SA-Adapters can be directly installed on the G215 and can be connected using a 9-pin D-Sub connector. Mechanically, a maximum of eight SA-Adapters can be mounted on a front panel with a width of up to 12HP, for example for implementing a CAN card with eight ports.

Using different SA-Adapters makes it possible to connect additional interfaces to the G215. This increases flexibility regarding the combination of different interfaces and the isolation requirements.

All I / O functions of the board are implemented inside the FPGA. It supports both RS232, RS422, RS485 UARTs in full duplex, half duplex or HDLC mode, optionally electrically isolated, and fieldbuses such as CAN, InterBus-S or the vehicle bus IBIS. As a new Altera® high-performance FPGA, the Cyclone® 4 is used, applications with the Nios® softcore, with its own intelligence are also imaginable. The direct connection of the Cyclone 4 to the backplane means customer-specific FPGA functions can be led to rear I / O and also offers the advantage of fast communication from the FPGA via PCI Express® at the backplane to the host CPU.

The G215 was developed for use in harsh environments. It is specified for an operating temperature of -40°C to +85°C, all components are soldered to withstand shock and vibration.
