The Si4320 is a single-chip, low-power, multi-channel FSK RF receiver designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 315 MHz, 433 MHz, 868 MHz and 915 MHz bands.
The Si4320 RF receiver is a highly integrated, flexible, low-cost solution that requires no production alignments. Used in conjunction with the Si4220/21 FSK transmitters, the Si4320 RF receiver allows developers to build robust, low-cost RF data links. It is ideal for high-volume wireless applications including remote control systems, home security and alarm systems, wireless keyboard/mouse and other PC peripherals, toys, and automotive applications including remote keyless entry and low tire pressure alerts. Industrial applications such as telemetry, personal/patient data logging, barcode readers and automatic meter reading are also supported.
The Si4320 RF receiver includes automatic frequency control (AFC) to ensure that the receiver is automatically tuned to the incoming signal. With the inclusion of the AFC, OEMs have the option to use inexpensive crystals and still be assured of the desired tuning.
