As part of the TCN (Train Communication Network) railway standard IEC 61375 the PP4 is designed to operate under harsh environmental conditions in accordance with EN 50155, e.g. -40 to +85°C, humidity etc. (standard versions with conformal coating).
The PP4 provides master and slave functionality and has one redundant MVB channel (double line attachment configuration) accessible via two 9-pin D-Sub connectors. It is based on the Siemens ASIC MVBCS1 and on an on-board FPGA. The functional device classes 1, 2, 3 and 4 of the MVB can be configured. The isolation voltage is 1500VDC/1000VAC.
• 32-bit/33-MHz PCI target
• MVB transmitter/receiver
• Master and slave interface
• 1 redundant channel
• Isolated EMD (optionally ESD and OGF)
• Up to 16 MB SDRAM, 2 MB Flash
• -40 to +85°C with qualified components
• Conformal coating
The PP4 provides 16 MB SDRAM for data and 2 MB Flash memory for different purposes, all permanently soldered.
It complies with the PCI-104 specification and can be stacked with other PCI-104 boards or mounted on different types of carrier boards. The bus interface is a 32-bit, 33-MHz PCI bus.
