Description
DRF7020D27 is a low-cost sub-1 GHz transceiver module designed for operations in the
unlicensed ISM (Industrial Scientific Medical) and LPRD bands. GFSK (Frequency Shift Keying)
modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking
performance make DRF7020D27 modules easy to realize the robust and reliable wireless link. The module can be configured to work in different channels with 200k Hz space. It adopts high
efficient looped interleaving EDAC (Error Detection and correction) coding with coding gain up
to 3dB which keeps in advance in EDAC and coding efficiency over normal FEC (Forward Error
Correction). Because of its high reliability in correction, modules can filter error and fake
information automatically and realize truly transparent wireless link, which makes DRF7020D27
very suitable in the rigid communication environment. DRF7020D27 integrates 256 bytes buffer. When the buffer is empty, users can transfer 256 bytes
data per time and even limitless data transfer can be achieved as long as RF data rate (RF module
to RF module) is configured to be faster than UART data rate (MCU to RF module). The module
provides standard UART/TTL interface for selection. Users can choose seven data rates and three
parity checks which make DRF7020D27 possibly tailor-made for different applications.
