HT8912 G3-PLC Powerline Transceiver

General Description

HT8912 is using OFDM modulation and demodulation technology of power line carrier communication chip, the use of advanced digital and analog mixed design technology and process, provide the power line high speed rate, high reliability, high sensitivity, data communication, data transmission can be realized and the application of various types of remote meter reading.

HT8912 is high integrated SOC chip, which will simulate the circuit, digital signal processors and 8051 MCU is fully implemented in a single chip. HT8912 uses orthogonal frequency division multiplexing (OFDM) modulation and demodulation, efficient transmission mode of FEC, flexible and can be equipped with reliable, so that it can be serious attenuation and pulse interference environment of power line under the strong adaptive signal to realize reliable communication at. HT8912 integrated 8051 kernel can be completed MAC layer and the above protocol required for a variety of functions and applications.

The HT8912 physical layer protocol is the international standard G3 basis, according to the Chinese power carrier to further optimize the environment to. HT8912 maximum support 1024 sub carrier, sub carrier using DPSK modulation, support DPBSK, DQPSK and D8PSK to realize the rate mode different, in order to realize the FEC reliable supports a variety of convolutional coding, so that in the environment of power line with different complicated noise can realize reliable communication.

HT8912 uses the 7*7mm LQFP48L package, the normal working temperature range from -40 ° C to +85 ° C, is a SOC chip with industrial grade.
