Description
Supply Voltage Pin. Operational range 2.7 V to 5.5 V.
Square-Domain Filter Pin. Connection for an external capacitor to lower the corner frequency of the square-
domain (or modulation) filter. Capacitor is connected between FLTR and V
8 kΩ on-chip resistor. The on-chip capacitor provides filtering with an approximate 100 kHz corner frequency.
For simple waveforms, no further filtering of the demodulated signal is required.
Signal Input Pin. Internally ac-coupled after internal termination resistance. Nominal 50 Ω input impedance.
Device Ground Pin.
Enable Pin. Connect pin to V
current less than 1 μA.
Output Pin. Rail-to-rail voltage output with limited 3 mA current drive capability. The output has an internal
100 Ω series resistance. High resistive loads are recommended to preserve output swing.
