PMC676TX Gigabit Ethernet Peripheral Component Interconnect Mezzanine Card

The PMC676TX is a Gigabit Ethernet Peripheral Component Interconnect Mezzanine Card (PMC) network interface card manufactured by GE Fanuc Embedded Systems. It has dual 10/100/1000BaseTX interfaces and is capable of full-duplex operation. The following are the detailed features and specifications of the product:

Product features:
Dual Gigabit Ethernet port: Provides two 10/100/1000BaseTX ports for full-duplex operation.
Powerful DMA engine: Each port has a powerful DMA (Direct Memory Access) engine equipped with very deep FIFO (First In, First Out) buffers up to 64K bytes, ensuring continuous, full-bandwidth operations while minimizing PCI overhead.
RJ-45 connector: The front RJ-45 connector is provided for easy connection.
No PCI-to-PCI bridge: The network interface card does not have a PCI-to-PCI bridge on the board.
Rich host offload capabilities: including checksum-based packet filtering, SNMP and RMON statistical counters, hardware TCP checksum offload, and support for multiple address filtering modes, such as 16 exact matches (unicast or multicast), 4096-bit hash filters for multicast frames, and mixed unicast and multicast.
Direct connection: Two PMC676TX boards can be connected directly via a simple “cross wire” to create a full-duplex 1000Mbit dedicated data path, providing high bandwidth at a very low cost.
Software Drivers: Provides software drivers for most popular operating systems, including Windows, Linux, VxWorks, LynxOS, and Solaris. These drivers are carefully designed and implemented to fit the host operating system’s LAN protocol stack so that all the facilities of the host OS can be used.

Technical specifications:
Front panel I/O connector: RJ-45
PCI controller/Ethernet MAC: Intel 82546
Port type: 10/100/1000BaseT
Application field:
The PMC676TX is widely used in areas where high performance interconnects are required, especially where real-time determinism is required. It is suitable for industrial automation, network communication, data center and other fields, and can be used as the core component of network switches, routers and other devices to provide high-speed and stable network connections.
