EZR32LG230F128R55G-B0

A Radio Frequency (RF) transceiver IC is a device capable of combining both receiving and transmitting frequencies into one integrated unit. It is generally represented by the acronym “RFIC”. The EZR32LG230F128R55G-B0 is one such integrated unit and is specifically designed for medium data rate (MDR) industrial and commercial communications systems using the 868 megahertz (MHz) radio spectrum.

The device features a highly integrated transceiver radio unit, a highly efficient Low Noise Amplifier (LNA) and a direct conversion architecture. It also includes a high output power amplifier, a Receive Signal Strength Indicator (RSSI) and digital modulation support. Furthermore, the EZR32LG230F128R55G-B0 features a fully integrated low power, spillover-free mode that enables ultra-low power operation, and is qualified in the high reliability automotive grade market.

EZR32LG230F128R55G-B0 application field comprises of various industrial and commercial applications such as home and industrial automation, energy systems, automotive and medical devices, asset tracking, RFID and machine-to-machine (M2M) solutions. Due to its high output power and direct conversion architecture, it is suitable for data transmission over several hundred meters.

This transceiver IC is based on an architecture that combines direct conversion, a Low Noise Amplifier, and a programmable RF switch. When the RF switch is in the low power inactive mode, the LNA is used to amplify both the transmit (Tx) and receive (Rx) signals. In the Transmit mode, the Low Noise Pre-Amplifier (LNPA) is used to boost the incoming image signal with an extremely low noise level. Then, the amplified transmit signal is processed by the Direct Conversion Receiver where the received signal is digitized and demodulated.

The EZR32LG230F128R55G-B0 is also capable of providing an up to 21dBm output power and a high signal sensitivity up to -113dBm with a broadband frequency range of up to 868MHz. The integrated transceiver supports programmable data rates up to 8 kbit/s and includes a dual channel architecture with an adjustable output power. The device also supports adjustable Coding Residency (CR) modulation and FEC (Forward Error Correction), as well as a 2-pin UART interface for communication.

The EZR32LG230F128R55G-B0 has an integrated RF parameter trimming unit which is able to precisely control the Transmit (Tx) gain, the RX gain, the frequency offset and the AFC level of the TX carrier. Moreover, the transceiver includes built-in LDOs, Temperature compensated Crystal Oscillator (TCXO) auto calibration, automatic low power mode, automatic warm-up and auto frequency hopping. These features make the EZR32LG230F128R55G-B0 suitable for various medical and industrial applications.

In summary, the EZR32LG230F128R55G-B0 is an integrated transceiver IC designed for medium data rate (MDR) industrial and commercial communications systems in the 868 MHz radio spectrum. It is capable of providing an output power of up to 21dBm, features RF parameter trimming capabilities, and includes built-in LDOs and a temperature compensated crystal oscillator auto calibration. Furthermore, this transceiver can support programmable data rates up to 8 kbit/s and is suitable for a variety of industrial and commercial applications.
