Description
RF input terminal
Antenna impedance nominal 50 Ω
GROUND terminal
The GND pins and the feet of the
shield case should be connected to a
wide GND plane.
Power supply terminal
DC 3.0 to 5.5 V
TX select terminal
GND = TXSEL active
To enable the transmitter circuits,
connect TXSEL to GND and RXSEL
to OPEN or 2.8 V.
RX select terminal
GND= RXSEL active
To enable the receiver circuits,
connect RXSEL to GND and TXSEL
to OPEN or 2.8 V.
Analogue output terminal
There is a DC offset of approx. 1 V.
Refer to the specification table for
amplitude level.
Clock terminal fof PLL data setting
input
Interface voltage H = 2.8 V, L = 0 V
