1 ENBL Device Enable. Connect this pin to VPOS to enter an enabled state. Connect this pin to ground to enter a disabled state. This pin can also be driven from a 3 V logic output. 2, 4 RFCM RF Input Ground Pins. The RFCM pins are connected to the exposed pad (EPAD) at the bottom of the package. Connect the RFCM pins to the system ground using a low impedance ground plane together with the EPAD. 3 RFIN Signal Input. The RFIN pin is ac-coupled and has a nominal 100 Ω RF input impedance. 5 VPOS Supply Voltage. The operational range of this pin is from 3.15 V to 5.25 V. Decouple the power supply using suggested capacitor values of 100 pF and 0.1 µF and place these capacitors as close as possible to the VPOS pin. 6 OCOM Output Common. Connect this pin to a low impedance ground plane together with the EPAD. 7 VOCM Output Common-Mode Control Input. This pin is internally biased to VPOS/2, nominal. An acceptable range on this pin is 0.9 V to VPOS/2. 8, 9 VENV−, Envelope Detector Pseudo Differential Outputs. VENV− and VENV+ are the negative and positive outputs, respectively, VENV+ for the envelope detector output. A 50 Ω output impedance per pin forms a 100 Ω differential output impedance. These pins feature a 100 Ω differential load and a 2 pF to ground per pin drive capability. 10 DCPL Bypass Pin for an Internal Bias Node. Connect this pin through a 0.1 µF capacitor to ground for best common- mode noise rejection. EPAD Exposed Pad. The exposed pad (EPAD) on the underside of the device is also internally connected to ground and requires good thermal and electrical connection to the ground of the printed circuit board (PCB). Connect all ground pins to a low impedance ground plane together with the EPAD.
