DRF4463D20 is a high efficient transceiver module designed for operations in the unlicensed ISM (Industrial Scientific Medical) and LPRD bands based on RFIC SI4463 from Silicon labs. GFSK modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking performance make DRF4463D20 modules easy to realize the robust and reliable wireless link.

The module can be configured to work in different channels. It adopts the high efficient looped interleaving EDAC (Error Detection and correction) coding with coding gain up to 3dB which keeps in advance in error correction and coding efficiency over normal FEC (Forward Error Correction) coding. Because of its high reliability in correction, modules can filter error and fake information automatically and realize truly transparent wireless link, which makes DRF4463D20 very suitable in the rigid communication environment.

DRF4463D20 integrates two 256 bytes buffer. When the buffer is empty, users can transfer nearly 256 bytes data per time and even limitless data transfer can be achieved as long as RF data rate is configured to be faster than UART data rate (MCU to RF module). DRF4463D20 provides standard UART/TTL interface. Users can choose seven data rates and three parity checks which make DRF4463D20 possibly tailor-made for different applications.
