4. 8-Pin Options
The standard 16-pin package allows complete control of all configurable features. Some reduced
function 8-pin versions are also available.
For high-volume applications additional customized 8-pin devices can be produced. SWEN, SEL0
and SEL1 pins are internally bonded to reduce the pin count. Pin 6 may be configured as either
SHUT or WAKEB.

Pin Function
Bandwidth Selection Bit 0 (Digital Input): Used in
conjunction with SEL1 to set the desired demodulator filter
bandwidth. See Table 1. Internally pulled-up to VDDRF
RF Power Supply: Ground return to the RF section power
supply.
Antenna (Analog Input): For optimal performance the
ANT pin should be impedance matched to the antenna. See
“Applications Information” for information on input
impedance and matching techniques
RF Power Supply: Positive supply input for the RF section
of the IC
Base-Band Power Supply: Positive supply input for the
baseband section (digital section) of the IC
Data Slicing Threshold Capacitor (Analog I/O): Capacitor
connected to this pin extracts the dc average value from the
demodulated waveform which becomes the reference for
the internal data slicing comparator
Not internally connected
Base-Band Power Supply: Ground return to the baseband
section power supply
