Summary: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 includes generating Status Frames and Data Frames to be communicated between the tuner and AFE and sending the generated Status Frames and Data Frames on a continual basis. 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.
