description STA3005 2/5 description STA3005 is a high-performance, fully programmable advanced radio receiver, designed to target am/fm/hd radio, speech and audio applications. it is a dual-if radio processor, with dynamically variable channel filtering; it also features both digital diversity (for dual-tuner systems) and digital directional antenna (single-tuner multiple antennas) for outs tanding recept ion capability. STA3005 is more than a radio-receiver; it features advanced audio processing, running on an emerald dsp for maximum flexibility and ef ficiency; sample rate converters, high- performance audio adcs, dacs and multiple industry-standard digital i/o-interfaces make STA3005 the right answer to high-performance audio-processing platforms. robust and customizable applications can be easily achieved thanks to the integrated arm7 microcontroller, which allows controllin g and monitoring all the internal peripherals.
