The TXMC391 is a Conduction Cooled Switched Mezzanine Card (CCXMC) compatible module providing a four channel 1000Base-KX Ethernet interface.
A PCIe Switch provides access to the Intel I210IS Gigabit Ethernet controllers. Each Ethernet interface supports 1000 Mbit/s transmission rate and is equipped with a 16 Mbit Serial Flash to support PXE and iSCSI boot.
The TXMC391 routes four Ethernet ports to the Back I/O P16 connector. All ports are mapped in the X12d range specified in VITA46.9 standard.
LEDs on the board indicate the different network activities.
The TXMC391 supports IEEE 1588/802.1AS Precision Time Protocol (PTP) and IEEE 802.1Qav Audio/Video Bridging (AVB) traffic shaping (with software extensions).
The SDP (Software Definable Pins) of each Ethernet Controller are connected to the Back I/O P16 connector for IEEE 1588 auxiliary device connections.
The TXMC391-10R routes these SDP directly to the Back I/O P16 connector. The TXMC391-20R has M-LVDS Transceivers between the Ethernet Controllers’ SDP and the Back I/O P16 connector to allow differential IEEE 1588 auxiliary device connections, the direction of these Transceivers is configured by the SDP.
The TXMC391 has an I²C board temperature sensor to facilitate measurement of the board heat near the Primary Thermal Interface of the Conduction Cooled Frame.
The module meets the requirements to operate in extended temperature range from -40 °C to +85 °C (Card Edge Temperature).
