EZR32HG220F32R68G-B0R working principle

The EZR32HG220F32R68G-B0R transceiver IC contains a transmitter, a receiver and a baseband processor. The transmitter utilizes a Direct Digital Modulator (DDM) to convert digital signal into an analog signal, which is transmitted over the air.On the receive side, the antenna receives the signal and the low-IF receiver topology of the transceiver IC uses a combination of analog baseband filters and digital demodulation algorithms to recover the digital data. The recovered data is then processed in the baseband processor.The baseband processor operates the radio and implements functions such as protocol stacks, link layers, etc. It also performs codec conversion and provides an interface to the host processor. The host processor is responsible for system-level functions and provides an interface to the peripheral subsystems.The EPC32HG220F32R68G-B0R transceiver IC is designed for ultimate flexibility and low power consumption. It utilizes an advanced low power consumption mode along with various hardware and software power management features to minimize its average power consumption.
