Integration’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 315 MHz, 433 MHz, 868 MHz, and 915 MHz bands. The IA4320 is a highly integrated, flexible, low-cost solution that requires no production alignments. Used in conjunction with Integration’s IA4220/21 FSK transmitters, the IA4320 allows the user to build robust, low-cost RF data links. As such, 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 alert. Industrial applications like telemetry, personal/patient data logging, barcode readers, and automatic meter reading are also supported.

The IA4320 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.
