Sunnyvale, Calif.—Designed for consumer and automotive applications,
Maxim Integrated Products has introduced the MAX2172 digital radio tuner for FM and digital audio broadcast (DAB) signals, with a high sensitivity for the FM, VHF, and L-band frequency ranges.
The MAX2172 integrates all components necessary to implement a complete tuner solution, including LNAs, mixers, an IF filter, and a fully synthesized local oscillator. Additionally, the IC integrates a front-end tracking filter to eliminate interference between the UHF, VHF, and FM bands. An on-chip received-signal-strength indicator (RSSI) and temperature sensor ensure fast, accurate scan and seek functions. The RSSI provides ±2dB accuracy and outputs the measured level in digital form through the I²C bus. FM sensitivity is -111dBm (typ), and FM adjacent-channel performance meets ETSI EN 55020.
The MAX2172 draws 61mA (typ) from a single 3V supply. It uses a standard 2.048MHz IF frequency that is compatible with most DAB digital demodulators. The device is packaged in a lead-free, 6mm x 6mm, 40-pin TQFN, and is fully specified over the -40 °C to +85°C extended temperature range.
Pricing: Starts at $4 (1000-up, FOB USA).
