Electrical Characteristics
VDDRF = VDDBB = VDD where 4.75V ≤ VDD ≤ 5.5V, VSS = 0V; VT/R = VSHUT = 0V; CAGC = 0.47µF, CTH = 4.7nF, 115kbps data-rate (Manchester
encoded); fREFOSC = 14.3359MHz (fRF = 915MHz); TA = 25°C, bold values indicate –40°C ≤ TA ≤ +85°C; current flow into device pins is positive; unless
noted.
