PI FU CTIO S
RFIN (Pin 1): RF Input Voltage. Referenced to VCC. A
coupling capacitor must be used to connect to the RF
signal source. The frequency range is 600MHz to 7GHz.
This pin has an internal 500Ω termination, an internal
Schottky diode detector and a peak detector capacitor.
GND (Pin 2): Ground.
VM (Pin 3): Comparator Negative Input. Apply reference
voltage to this pin.
LEN (Pin 4): Latch Enable Input. Output is latched when
LEN is high and transparent when LEN is low.
VOUT (Pin 5): Comparator Output.
VCC (Pin 6): Power Supply Voltage, 2.7V to 5.5V.
VCC should be bypassed appropriately with ceramic
capacitors.
