Pinout and package

Package8-Lead LFCSP (2 mm × 3 mm)

PinNameFunctionSource
1INHI: RF Input. Nominal input range of -50 dBm to 0 dBm, re: 50 Ω; ac-coupled RF input.
2COMM: Device Common. Connect this pin to a low impedance ground plane.
3CLPF: Loop Filter Capacitor. In measurement mode, this capacitor sets the pulse response time and video bandwidth. In controller mode, the capacitance on this node sets the response time of the error amplifier/integrator.
4VSET: Setpoint Control Input for Controller Mode or Feedback Input for Measurement Mode.
5VOUT: Measurement and Controller Output. In measurement mode, VOUT provides a decreasing linear-in-dB representation of the RF input signal amplitude. In controller mode, VOUT is used to control the gain of a VGA or VVA with a positive gain sense (increasing voltage increases gain).
6TADJ: Temperature Compensation Adjustment. Frequency dependent temperature compensation is set by connecting a ground referenced resistor to this pin.
7VPOS: Positive Supply Voltage, 3.0 V to 5.5 V.
8INLO: RF Common for INHI. AC-coupled RF common.
EPADEPAD: The pad is internally connected to COMM; solder to a low impedance ground plane.
