Description STA3005
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 outstanding reception capability.
STA3005 is more than a radio-receiver; it features advanced audio processing, running on
an EMERALD DSP for maximum flexibility and efficiency; sample rate converters, highperformance 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 controlling and monitoring all the internal peripherals.
