PMC677RCLC Network Interface Card

High-speed flexibility

The PMC677RCLC features four ports of full-duplex Gigabit Ethernet using LC connectors with 1000BaseSX transceivers, making it a flexible option for system designers looking to add high-speed connectivity to their platforms. There is also a copper TX (RJ-45) version of the product (PMC677RCTX)

Performance without increased system overhead

The Ethernet/PCI interface on the PMC676RCSC 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 counters
• Hardware 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.

Comprehensive driver offering

Software drivers are available for most popular operating systems including VxWorks, Linux, LynxOS, Windows 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.
