DESCRIPTION
Si4322
PIN ASSIGNMENT
Silicon Labs’s Si4322 is a single chip, low power, multi-channel FSK receiver
designed for use in applications requiring FCC or ETSI conformance for
unlicensed use in the 868 and 915 MHz bands. Used in conjunction with

Silicon Labs’ FSK transmitters, the Si4322 is a flexible, low cost, and highly
integrated solution that does not require production alignments. All required
RF functions are integrated. Only an external crystal and bypass filtering is
needed for operation.
The Si4322 has a completely integrated PLL for easy RF design, and its

rapid settling time allows for fast frequency hopping, bypassing multipath
fading, and interference to achieve robust wireless links. The PLL’s high
resolution allows the usage of multiple channels in any of the bands. The
baseband bandwidth (BW) is programmable to accommodate various
deviation, data rate, and crystal tolerance requirements. The receiver employs
the Zero-IF approach with I/Q demodulation, therefore no external
components (except crystal and decoupling) are needed in a typical
application. The Si4322 is a complete analog RF and baseband receiver
including a multi-band PLL synthesizer with an LNA, I/Q down converter
mixers, baseband filters and amplifiers, and I/Q demodulator.

FEATURES
? Fully integrated (low BOM, easy design-in)
? No alignment required in production
? Fast settling, programmable, high-resolution PLL
The chip dramatically reduces the load on the microcontroller with integrated
digital data processing: data filtering, clock recovery, data pattern recognition
and integrated FIFO. The automatic frequency control (AFC) feature allows
using a low accuracy (low cost) crystal. To minimize the system cost, the chip
can provide a clock signal for the microcontroller, avoiding the need for two
crystals.
