Analog Devices’ RF products for industrial, commercial, and consumer applications
ADI’s ADF7242 is a global 2.4 GHz ISM transceiver. This transceiver was designed to support IEEE 802.15.4-2006 2.4 GHz PHY requirements as well as proprietary GFSK/FSK/GMSK/MSK modulation schemes in both packet and data streaming modes. With a minimum number of external components, it achieves compliance with the FCC CFR47 Part 15, ETSI EN 300 440 (Equipment Class 2), ETSI EN 300 328 (FHSS, DR > 250 kbps), and ARIB STD T-66 standards.
The ADF7242 complies with the IEEE 802.15.4-2006 2.4 GHz PHY requirements with a fixed data rate of 250 kbps and DSSS-OQPSK modulation. With its support of GFSK/FSK/GMSK/MSK modulation schemes, the IC can operate over a wide range of data rates from 50 kbps to 2 Mbps and is, therefore, equally suitable for proprietary applications in the areas of smart metering, industrial control, home and building automation, and consumer electronics. In addition, the agile frequency synthesizer of the ADF7242, together with short turnaround times, facilitates the implementation of FHSS systems.
The ADF7242 incorporates a very low power custom 8-bit processor that supports several transceiver management functions. These functions are handled by the two main modules of the processor: the radio controller and the packet manager. The ADF7242 is ideal for wireless sensor networks, industrial wireless control, and smart metering applications.
