Description
The STA710 is a single chip, full CMOS, quad-band, dual channel front-end tuner
specifically tailored to Software-Defined-Radio (SDR) systems.
When paired with an application processor, STA710 enables the implementation of a
SDR solution to receive analog (AM/FM/WX) and digital terrestrial broadcasting
standards (e.g. HD-Radio™/DAB/DRM).
The STA710 features front-end low-noise amplifiers (LNAs) covering AM band
(LW/MW/SW), FM and WX bands, DAB band-III and band-L.
After on-chip IF filtering, the STA710 digitizes the signal with a high dynamic range
ΣΔ ADC ahead of the complex phase-quadrature base-band signal down conversion
to provide a stable digital base-band output to the companion application processor.
The digital base-band signal is transmitted to the application processor via a flexible
and configurable serial digital interface operating either as single-ended I2S, LVDS
I2S or JESD204B.
The STA710 dual channel architecture enables a straightforward implementation of
audio/data foreground-background reception strategies and multipath interference
mitigation algorithms such as FM phase-diversity, DAB/DRM Maximal-Ratio-
Combining (MRC) inside the companion application processor.
The STA710 offers automotive grade and state-of-art RF performances with minimum
external component count.
