DOCSIS Mainboard

Assembly

The digital core: a DOCSIS 3.1 SoC demodulates OFDM and SC-QAM channels from the tuner samples, runs the MAC and security stack, and bridges the result to Ethernet, backed by DDR memory and flash. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
