The PP4 is an optically isolated MVB (Multifunction Vehicle Bus) transmitter and receiver interface with EMD (Electrical Middle Distance medium) physical interface. Versions with ESD (Electrical Short Distance medium) and OGF (Optical Glass Fiber medium) are available on request.
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.
Features • 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.
