Holston Micro Systems has announced the Blackfin RJ 10/100/1000Base-T to PCI-Express network adapters that promise to offer a complete modular network adapter interface implemented in an extremely small footprint. According to the company, the compact size and light weight of the Blackfin RJ pluggable modules make them ideal for applications where platform size constraints, installation in difficult to access areas or platform mobility are crucial design considerations.

Blackfin RJ network adapters integrate an Intel I210 PCI-Express network controller plus isolation filters and transformers into a modular pluggable component with an RJ-45 interface. Holston provides alternative modules with MMF or SMF LC fibre optic connectors enabling the same motherboard to support either copper or fibre optic network cable infrastructures without redesign.

The network adapters support the IEEE-802az Energy Efficient Ethernet (EEE) standard. During periods of low network activity, EEE reduces platform power consumption by negotiating with its link partner to transition to a low power idle (LPI) operating mode. The motherboard electrical interface for the Blackfin RJ pluggable network adapter is a Samtec SMT connector with a 20 position footprint. The RJ-45 connector interface supports most popular UTP and STP network media options including CAT 3, 4, 5 and 6 cable structures.

The network adapters feature: complete PCI-Express network adapter integrated into an RJ-45 connector form factor; Intel I210 Ethernet controller for PCI Express Gen 2.1 at 2.5GT/s for x1 width (lane); swappable pluggable unit for fibre optic LC modules with identical motherboard layout; IEEE 802.3, 802.3u, 802.3ab compliant for multi-rate network topology support; automatic cable crossover detection function (MDI/MDI-X) that configures interface polarity as required; and Intel System Management Bus (SMBus) pass through that enables IPMI/BMC configuration of controller interface.

These devices are sampling.
