.DaIntegration’s IA4320 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
w315, 433, 868, and 915 MHz bands. Used in conjunction with IA4220/21, Integration
wAssociates’ FSK transmitters, the IA4320 is a flexible, low cost, and highly integrated
solution that does not require production alignments. All required RF functions are
wintegrated. Only an external crystal and bypass filtering are needed for operation.
mThe IA4320 has a completely integrated PLL for easy RF design, and its rapid
settling time allows for fast frequency hopping, bypassing multipath fading, and
ointerference to achieve robust wireless links. The PLL’s high resolution allows
.cthe 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
Utypical application. The IA4320 is a complete analog RF and baseband receiver
including a multi-band PLL synthesizer with an LNA, I/Q down converter mixers,
t4baseband filters and amplifiers, and I/Q demodulator.
The chip dramatically reduces the load on the microcontroller with integrated
edigital data processing: data filtering, clock recovery, data pattern recognition
and integrated FIFO. The automatic frequency control (AFC) feature allows using
ea 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.
hFor simple applications, the receiver supports a standalone operation mode. This
allows complete data receiver operation and control of four digital outputs based
Son the incoming data pattern without a microcontroller. In this mode, 12 or more
tapredefined frequency channels can be used in any of the four bands. For low power
applications, the device supports low duty-cycle operation based on the internal
wake-up timer.
