... A formula for the receiver bandwidth can be summarized as follows LD_en PF_FC1 PF_FC0 In battery operated applications that do not need very high selectivity, the main channel filter can be bypassed by SC_by=1.

... To compensate for this, the receivers XCO frequency should be increased recommended to use Mode UP+DN for two reasons, you do not need to know the actual frequency deviation and this mode gives the best accuracy. 16 MICRF620/MICRF620Z FEEC_1 FEEC_0 FEE Mode 0 0 Off ...
