RF90 Weather Band and SAME Data Receiver RF Wireless Modules

The RF90 is the industry's first weather band(WB)radio receiver IC to include a specific area message
encoding(SAME) processor. Offering

Description:
The RF90 is the industry's first weather band(WB)radio receiver IC to include a specific area message encoding(SAME) processor. Offering unmatched integration and PCB space savings, the RF90 requires only one external component and less than 15 mm 2 of board area. Available in a tiny 3 x 3 mm QFN package, it eliminates the need for a front-end tuner IC, external ADC, DSP processor, RAM, and numerous discrete components found in traditional SAME weather band radios. The RF90 weather band receiver provides the space savings and low power consumption necessary for portable devices while delivering the high performance and design simplicity desired for all weather alert radios.

Leveraging HopeRF’s new RF90 FM tuner's digital low intermediate frequency(low-IF)receiver architecture, the RF90 delivers superior RF performance combined with sophisticated digital processing to yield best-inclass audio quality and SAME data sensitivity. The high integration and complete system production test simplifies design in, increases system quality, and improves manufacturability.

The RF90 is a feature-rich solution including 1050 Hz tone detection, automatic frequency control, dynamic channel bandwidth filters, and digital tuning. In addition, the RF90 provides a programmable reference clock and supports an I 2C compatible 2-wire control interface, SPI, and a RF90 backwards compatible 3-wire control interface. The RF90 incorporates a digital processor to provide SAME data, advance error correction, and SAME data quality metrics. Using this feature, the RF90 enables broadcast alert data such as severe thunderstorm warning or flash flood watch to be displayed to the user.

HopeRF provide total solutions both for hardware & software together with just in time support all the necessary development tools in order to speedup customer’s development cycle time.
