PIN FUNCTIONS

VCC (Pin 1): Power Supply, 2.7V to 5.25V. VCC

should be bypassed with a 0.1μF ceramic capacitor.

EN (Pin 2): Chip Enable. A logic low or no-connect on the

enable pin shuts down the part. A logic high enables the

part. An internal 500k pull-down resistor ensures the part is

off when the enable driver is in a three-state condition.

VOUT (Pin 3): Detector Output.

GND (Pins 4, 5, 6): Ground.

RFIN(Pin7):RFInput.ShouldbeDC-blockedwithcoupling

capacitor; 1000pF recommended. This pin has an internal

200Ω termination.

CSQ (Pin 8): Optional Low Frequency Range Extension

Capacitor. This pin is for frequencies below 250MHz. Use

0.01μF from pin to ground for 10MHz operation.

Exposed Pad (Pin 9): Ground. The Exposed Pad must

be soldered to the PCB. For high frequency oper-

ation, the backside ground connection should have a low

inductance connection to the PCB ground, using many

through-hole vias. See the layout information in the Ap-

plications Information section.
