TQMC801: 1000BASE-KX Ethernet QMC Module with PTP Synchronization

1000BASE-KX Gigabit Ethernet in QMC form factor

The TQMC801 expands the TEWS Technologies embedded I/O portfolio with a compact Ethernet networking mezzanine.

The single-width VITA 93.0 QMC module measures 78 × 25.8 mm and provides one 1000BASE-KX Ethernet channel. It connects to the host through a PCI Express Revision 2.1 Gen1 x1 interface.

This provides a compact way to integrate Gigabit Ethernet connectivity into embedded systems with a compatible QMC site.

Intel I210IS Gigabit Ethernet controller

The Ethernet interface is based on an Intel I210IS Gigabit Ethernet controller accessible through PCI Express.

A 16 Mbit serial Flash stores configuration data and provides memory for the Boot ROM, supporting PXE and iSCSI boot.

IEEE 1588 and IEEE 802.1AS PTP synchronization

The TQMC801 supports IEEE 1588 / IEEE 802.1AS Precision Time Protocol with PTP v1 and v2 frame formats.

Software Definable Pins from the Ethernet controller are connected to the QMC I/O connector to support auxiliary devices used in IEEE 1588 applications.

These capabilities are particularly relevant to Information & Communication Systems where several networked embedded devices need access to coordinated timing information.

For further background on Ethernet synchronization and time-aware networking mechanisms, see the ECRIN Systems guide to Time-Sensitive Networking and its comparison with AFDX.

IEEE 802.1Qav AVB traffic shaping

The TQMC801 also supports IEEE 802.1Qav Audio/Video Bridging traffic shaping with software extensions.

Combined with PTP synchronization capabilities, this provides traffic-management functions for Ethernet applications with specific timing requirements.

The TQMC801 remains a single-channel Ethernet interface, however, and should not be presented as a complete multi-function TSN switch.

Thermal monitoring and network activity

An onboard I²C temperature sensor monitors board temperature near the Ethernet controller.

Integrated LEDs also provide network activity indications.

Air- and conduction-cooled variants

The TQMC801 is available in two versions:

• TQMC801-10R-A – air cooled
• TQMC801-10R-H – conduction cooled

Both operate from -40°C to +85°C and support the same -40°C to +85°C storage range. Humidity is specified at 5–95% non-condensing.

These options support integration into Defense, Aerospace & Security applications as well as industrial and other embedded platforms.

Integrating the TQMC801 into an embedded Ethernet platform

The TQMC801 requires a compatible QMC carrier or host platform.

For CompactPCI Serial systems, the TCPS210 provides up to three single-width QMC sites, PCIe Gen3 x4 connectivity and rear QMC I/O routing through P2, P3 and P4.

For standard PCI Express platforms, the TPCE210 dual-QMC carrier supports two single-width QMC modules or one double-width module.

The TQMC801 can therefore become the network interface within a wider embedded platform combining computing, digital I/O, CAN, serial communications or acquisition functions.

For complete systems, ECRIN Systems can integrate these technologies through its COTS and Modified COTS approach and handle production and system integration according to project requirements.
