NAT-MCH-PHYS80 MTCA Carrier Hub for MTCA.4 and MTCA.4.1 applications
Supports GbE and PCIe Gen 3 switching and optical & copper PCIe x8/x16 uplinks
The NAT-MCH-PHYS80 addresses the requirements for higher bandwidth to both AMCs and the MCH-RTM as well as for optical and copper uplinks in PCIe based MTCA.4 systems. These features make it ideal for large control and data acquisition applications such as high and low energy physics research institutions.
The NAT-MCH-PHYS80 fully supports redundant management and power environments. Frequent exchange of the internal databases with the secondary MCH and a heart beat mechanism ensure an immediate switch-over from the primary to the secondary MCH whenever it becomes necessary.
