1 FLTR Modulation Filter. Connect an external capacitor to this pin to lower the corner frequency of the modulation filter. 2 VPOS Supply Voltage. The operational range is 2.5 V to 3.3 V. 3 RFIN Signal Input. This pin is internally ac-coupled after internal termination resistance. The nominal input impedance is 500 Ω. 4 COMM Device Ground. 5 VRMS RMS Output. This pin is a rail-to-rail voltage output with limited current drive capability. The output has an internal 100 Ω series resistance. High resistive loads and low capacitance loads are recommended to preserve output swing and allow fast response. 6 ENBL Enable. Connect this pin to VS for normal operation. Connect this pin to ground for disable mode. Rev.
