NAT-MCH - Mezzanine Modules
Flexible configuration options for the NAT-MCH MicroTCA Carrier Hub






Clock MezzanineThe Clock Mezzanine Module allows a flexible selection of the telecom and non-telecom clocking structures as defined in MicroTCA.0. The on-board Stratum 3/3E type PLL sources its clock reference configurably from either any of the 12 AMCs or from an external clock via the front panel BNC type connector. In conjunction with the PCIe Hub module it provides a PCIe compliant fabric clock (FCLKA) to all AMC slots. This can be either a 100MHz fixed or 100MHz Spread Spectrum clock (SSC) at HCSL signaing level. Key Features:

Physics Clock MezzanineBeside the standard clock mezzanine, N.A.T. offers a clock mezzanine for Physics. The development of this module is driven by the demand of physics groups requiring very low jitter and constant latency. These features are realised by using a special Clock Multiplexer developed in cooperation with IDT (Integrated Device Technology Inc.). Key features:

NAT-MCH double-width with µRTM COM Express CarrierThe new double-width MCH can be used as a standalone product in all systems requiring the double-width form factor. It is ideally suited for MTCA.4 applications allowing the use of MicroTCA rear transition modules (µRTM). Combining this MCH with the µRTM COM Express Carrier, allows you to use the unused space behind the MCH. The COM Express carrier can be equipped with any Type 6 Computer on Module (COM) Express module that suits your system requirements. The benefit of using COM Express modules is the broad range of configurations (processor architecture, performance, memory, etc.), a rich offering by various manufacturers, long-term availability and system configuration flexibility.
