Each Frame is a 10-bit K.28 Comma Sync word followed by a payload and when no data is queued to be communicated, Status Frames are sent asynchronously as filler frames."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-speed serial interface for orthogonal frequency division multiplexing (OFDM) cable modems","description":"A high-speed serial interface (HSIF) for communicating between an analog front end (AFE) and a System on a Chip (SoC) digital radio via a bi-directional serial bit connection for an OFDM cable modem i","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11296920","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
