Подскажите какие существуют интерфейсы для передачи данных по шлейфам и кабелям на скорости 50-200 Мb/s.
Все интерфейсы, которые мне известны - либо низкоскоростные(до 20 Мb/s, CAN, RS-484, SPI), либо высокоскоростные(от 500 Мb/s, DVI, HDMI, PCI-E итд). Существуют ли стандартизованные "среднескоростные " интферфейсы?
Interlaken
Protocol Definition,
A Joint Specification of Cortina Systems and Cisco Systems, Revision 1.2, October 7, 2008
Interlaken is a narrow, high-speed channelized chip-to-chip interface. It is characterized by
the following features:
• Support for 256 communications channels, or up to 64K with channel extension
• A simple control word structure to delineate packets, similar in function to SPI4.2
• A continuous Meta Frame of programmable frequency to guarantee lane alignment,
synchronize the scrambler, perform clock compensation, and indicate lane health
• Protocol independence from the number of SerDes lanes and SerDes rates
• Both out-of-band and in-band per-channel flow control options, with a simple Xon/Xoff
semantic
• 64B/67B data encoding and scrambling
• Performance that scales with the number of lanes
