product description:
High-speed connectivity
The PMC676RCTX delivers two 10/100/1000BaseT full-duplex Ethernet ports in the modular PMC form factor providing system integrators a simple method to add high-speed Ethernet connectivity to almost any embedded system. It supports RJ-45 TX connectors; a version of the product is also available with fiber SC or LC interfaces (PMC676RCSC)
Low system overhead
The Ethernet/PCI/PCI-X interface on the PMC676RCTX includes a powerful DMA engine for each port with very deep FIFO buffers (64K byte). This assures continuous, full bandwidth operation with minimum PCI overhead.
This feature-rich network interface card provides a suite of host off-loading features including:
- Packet filtering based on checksum errors
- SNMP and RMON statistic countersHardware
- TCP checksum off-loadingSupport for various address filtering modes such as 16 exact matches (unicast or multicast),
- 4096-bit hash filter for multicast frames and promiscuous unicast and multicast.
Two PMC676RCTX boards can be directly cabled with a simple “cross-over”. This configuration creates a full duplex 1000Mbit dedicated data path – delivering high bandwidth at very low cost. More complex, dedicated interconnects can be created using a hub or switch. Both point-to-point and switched hubs, in full duplex mode, remove many determinism concerns raised with traditional Ethernet solutions. This makes the PMC676RCTX an excellent candidate for high performance interconnects that require real time determinism.
A range of option
Software drivers are available for most popular operating systems including Windows, Linux, LynxOS, VxWorks, and Solaris. These drivers have been carefully designed and implemented to integrate into the native LAN protocol stack of host operating systems allowing full user control over the Ethernet interfaces. Solaris OBP and PXE boot options are available, and a conformal coating option.
