Pin Description
PIN NAME FUNCTION
1 PAVDD
Power-Amplifier Supply Voltage. Bypass to GND with 0.01µF and 220pF capacitors placed as close
as possible to the pin.
2 ROUT
Envelope-Shaping Output. ROUT controls the power-amplifier envelope’s rise and fall times. Connect
ROUT to the PA pullup inductor or optional power-adjust resistor. Bypass the inductor to GND as
close as possible to the inductor with 680pF and 220pF capacitors as shown in the Typical
Application Circuit.
3 TX/RX1
Transmit/Receive Switch Throw. Drive T/R high to short TX/RX1 to TX/RX2. Drive T/R low to disconnect
TX/RX1 from TX/RX2. Functionally identical to TX/RX2.
4 TX/RX2 Transmit/Receive Switch Pole. Typically connected to ground. See the Typical Application Circuit.
5 PAOUT
Power-Amplifier Output. Requires a pullup inductor to the supply voltage (or ROUT if envelope
shaping is desired), which may be part of the output-matching network to an antenna.
6 AVDD
Analog Power-Supply Voltage. AVDD is connected to an on-chip +3.0V regulator in 5V operation.
Bypass AVDD to GND with 0.1µF and 220pF capacitors placed as close as possible to the pin.
7 LNAIN Low-Noise Amplifier Input. Must be AC-coupled.
8 LNASRC
Low-Noise Amplifier Source for External Inductive Degeneration. Connect an inductor to GND to set
the LNA input impedance.
9 LNAOUT
Low-Noise Amplifier Output. Must be connected to AVDD through a parallel LC tank filter. AC-couple
to MIXIN+.
10 MIXIN+ Noninverting Mixer Input. Must be AC-coupled to the LNA output.
11 MIXIN- Inverting Mixer Input. Bypass to AV
DD
with a capacitor as close as possible to LNA LC tank filter.
12 MIXOUT 330Ω Mixer Output. Connect to the input of the 10.7MHz filter.
13 IFIN- Inverting 330Ω IF Limiter Amplifier Input. Bypass to GND with a capacitor.
14 IFIN+ Noninverting 330Ω IF Limiter Amplifier Input. Connect to the output of the 10.7MHz IF filter.
15 PDMIN Minimum-Level Peak Detector for Demodulator Output
16 PDMAX Maximum-Level Peak Detector for Demodulator Output
17 DS- Inverting Data Slicer Input
18 DS+ Noninverting Data Slicer Input
19 OP+ Noninverting Op Amp Input for the Sallen-Key Data Filter
20 DF Data Filter Feedback Node. Input for the feedback of the Sallen-Key data filter.
21 RSSI Buffered Received-Signal-Strength Indicator Output
22 T/R
Transmit/ Receive. Drive high to put the device in transmit mode. Drive low or leave unconnected to
put the device in receive mode. It is internally pulled down. This function is also controlled by a
configuration register.
23 ENABLE
Enable. Drive high for normal operation. Drive low or leave unconnected to put the device into
shutdown mode.
24 DATA Receiver Data Output/Transmitter Data Input
25 CLKOUT Divided Crystal Clock Buffered Output
26 DVDD
Digital Power-Supply Voltage. Bypass to GND with 0.01µF and 220pF capacitors placed as close as
possible to the pin.
