DESCRIPTION
DRF1212D10 is a low-cost sub-1 GHz transceiver module designed for operations in the
unlicensed ISM (Industrial Scientific Medical) and LPRD bands. FSK (Frequency Shift Keying)
modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking
performance make DRF1212D10 modules easy to realize the robust and reliable wireless link.
The module can be configured to work in different channels with 200 KHz space. It adopts 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
DRF1212D10 very suitable in the rigid communication environment.
DRF1212D10 integrates two 256 bytes buffer. When the buffer is empty, users can transfer nearly
