RF83//RF83C/RF83L/RF83CL ASK/OOK Receiver V2.0
11. Electrical Characteristics
For RF83/RF83C,V_DDRF = V_DDBB = V_DD where +4.75V ≤ V_DD ≤ 5.5V(RF83/RF83C); For
RF83L/RF83CL V_DDRF = V_DDBB = V_DD where +2.75V ≤ V_DD ≤ 3.3V; V_SS = 0V; C_AGC = 4.7µF, C_TH
= 100nF; SEL0=0, SEL1 = V_SS; fixed mode; For 315MHz,f_REFOSC = 4.8970MHz; For
315MHz,f_REFOSC = 6.7458MHz;data-rate = 1kbps (Manchester encoded). T_A = 25°C, bold values
indicate –40°C ≤ T_A ≤ +85°C;current flow into device pins is positive; unless noted.
