37、ontrolled by controlling the input power.The CC2591 PA is designed to work incompression(class AB),and the best efficiency is reached when a strong input signal is applied.Input Levels on Control PinsThe four digital control pins(PAEN,EN,HGM,RXTX)have built-in level-shifting functionality,meaning th

38、at if theCC2591 is operating from a 3.6-V supply voltage,the control pins will still sense 1.6-V-1.8-V signals as logical1.An example of the above would be that RXTX is connected directly to the RXTX pin on CC24xx,but the globalsupply voltage is 3.6 V.The RXTX pin on CC24xx will switch between 0 V(R

39、X)and 1.8 V(TX),which is still ahigh enough voltage to control the mode of CC2591.The input voltages should however not have logical 1 level that is higher than the supply.Connecting CC2591 to a CC24xx DeviceTable 3.Control Logic for Connecting CC2591 to a CC24xx DevicePAEN=ENRXTXHGMMODE OF OPERATIO
