1. Describe

AMIS-30585 is a single-chip modem dedicated to Power line carrier (PLC) communication conforms to European standards IEC 1334-5-1 and IEC 1334-4-32. S-FSK is a modulation and demodulation technology Combines some of the advantages of classic spreads Spectrum system (such as anti-narrowband Interference) has the advantages of the classic FSK system (Low complexity). Transmitter allocates space Frequency fs to "data 0" and mark frequency fm to "data 1". The difference between S-FSK and classic FSK Is that fs and fm are now far away from each Other, making their transmission quality independent of Each other (the intensity of the small interference and Signal attenuation in two independent frequency). Supported frequency pairs AMIS-30585 has a typical 10 kHz interval. The circuit is mainly digital. Analog conversion The signal is executed at the front end of the circuit. This Signal processing and protocol processing are digital. On the back end, the interface of the application It is done through the serial interface. Digital processing The signal is in a hardwired block and a Microprocessor block. Microprocessor controlled by firmware. Where timing is most critical, the function is Realize with dedicated hardware. For function Where timing is not important, usually a higher level Function, circuit uses ARM 7TDMI Microprocessor core. The processor runs DSP algorithms, and at the same time, Handling the communication protocol. communicate In this application, the protocol contains MAC = Medium Access control layer. The program runs on The microprocessor is stored in the onboard ROM. This The work data required for processing is stored in Internal RAM. For the back end, link to Application hardware, provide SCI. SCI is simple Use serial interface to allow communication Between external processors for applications Software and AMIS-30585 modem. SCI is committed to Two wires: TXD and RXD. The baud rate is determined by Set 2 bits (BR0, BR1). Due to processing low protocol layers Circuit, AMIS-30585 provides an innovative The building is split. Thanks to this, users can benefit from A higher-level interface to the PLC media. Compared with the physical layer interface, AMIS-30585 allows faster application development. The user only needs to send the raw data to AMIS-30585 And no longer need to deal with agreement details Transmission through a specific medium. This last part Usually accounts for 50% of software development cost.
