Pin Descriptions
Pin Name I/O Description
1 GND Ground
2 ANTENNA I/O 50-ohm RF Antenna Port
3 GND — Ground
4 VCCP — Supply Voltage / advised NC
5 VCCA — Supply Voltage
6 GND — Ground
7 VCC — Supply Voltage
8 EN I
3-wire Interface Communication Enable
Signal.
9 SWITCH I/O
Selects between two pre-configured states,
e.g. transmit and receive. The states are
determined by the SWParam register.
10 GND I Ground
11 GND I Ground
12 SO O Data output of the 3-wire interface
13 SI I Data input of the 3-wire interface
14 SCK I Data clock of the 3-wire interface
15 CLKOUT O
Programmable Clock Output:
F
XTAL
divided by 4, 8, 16 or 32
16 DCLK O Receiver Data Clock
17 DATA I/O
Transmitter Data Input and Receiver
Data Output. This is a bi-directional line
that changes based on the module’s
TX/RX state. This line can be set to the
receiver data output only by disabling the
bidirectional data in the ADParam register.
18 DATAIN I
Transmitter Data Input. This line is the
transmitter data input when bidirectional
data is disabled using the ADParam register.
This line is not used when bidirectional data
is enabled.
19 PATTERN O
Output of the Pattern Recognition Block.
This line goes high when the module detects
a received bit pattern that matches a pattern
stored in the Pattern configuration register.
20 RX I
Antenna Switch RX Select. Set high for
receive mode; must be set opposite the TX
line
21 TX I
Antenna Switch TX Select. Set high for
transmit mode; must be set opposite the
RX line.
