The multimedia interface includes a bidirectional auxiliary data channel with source-side and sink-side isolation transformers. An extended-range EMI hardened interface device may prevent signal loss over longer cable runs by using the transformer in a BALUN configuration and utilizing coaxial cabling and source-side RF amplifiers to boost high-frequency gain. Interface devices may incorporate source-side and sink-side BALUNs or tri-filar RF transformers with AC coupling via serial capacitors to improve efficiency at high frequencies."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"EMI hardened displayport interface","description":"An EMI-hardened multimedia interface device compatible with high-speed DisplayPort data transmission incorporates coupled isolation transformers on the source and sink sides for transmitting high-pass","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10490954","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.
