The Si4322 single-chip, low-power, multi-channel FSK receiver is 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, cost-effective, and highly integrated solution that does not require production alignments. All required RF functions are integrated. Only an external crystal and bypass filtering are needed for operation. The Si4322 has a completely integrated PLL for easy RF design, and its rapid settling time enables for fast frequency hopping, bypassing multipath fading, and interference to achieve robust wireless links. The PLL's high resolution supports multiple channels in any of the bands. The baseband bandwidth (BW) is programmable to accommodate various deviation, data rate and crystal tolerance requirements.
