Abstract
A high-speed serial interface (HSIF) for communicating between an analog front end (AFE) and a radio via a bi-directional serial bit connection for an OFDM device.
Claims19
A communication device, comprising:
- a digital signal processor (DSP) including a first high-speed serial interface (HSIF) configured to receive data from an analog front end (AFE), wherein the HSIF and the DSP reside on a same integrated circuit,
- wherein the HSIF is configured to provide framed data that is 8b/10b-encoded and begins with a comma synchronization symbol,
- wherein the data from the AFE comprising a control portion followed by a payload,
- the data including at least one redundant byte for error detection, wherein the data comprising at least one status frame.
1 more element
A device configured to communicate orthogonal frequency division multiplexed (OFDM) signals upstream and downstream with a network, the device comprising:
- a first high speed serial interface (HSIF) to send and receive frames over a bi-directional serial connection to and from an analog front end (AFE) and a digital component in the form of status and data frames being 8b/10b-encoded and beginning with a comma synchronization symbol;
- and
- a Serializer/Deserializer (SerDes).
