Description

The STA709 is a single chip, full CMOS, quad-band, front-end tuner specifically

tailored to Software-Defined-Radio (SDR) systems.

When paired with an application processor, STA709 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 STA709 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 STA709 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 STA709 offers automotive grade and state-of-art RF performances with minimum

external component count.
