TDA7707：multi-standard IC tuner

The TDA7707 is a single chip fully-CMOS quad-band, dual-channel tuner for analog and digital terrestrial radio receiver applications.

The TDA7707 features multiple front-end low-noise amplifiers (LNAs) to cover AM LW/MW/SW bands, the entire FM band, DAB band-III and band-L, with advanced DSP-controlled automatic gain control (AGC) amplifier and mixer stages.

After on-chip IF filtering, the TDA7707 digitizes the signal with a very high dynamic range ADC; it processes the complex phase-quadrature base-band signal allowing applications like FM phase-diversity, integrated background tuner, and dual channel HD-Radio™ and DAB filtering. The double HD-Radio™/DAB base-band output signal is suitable for direct transmission to the STA680 HD-Radio™ decoder or STA660 DAB/DRM decoder through a dedicated low-EMI serial interface.

In combination with the STA680 HD-Radio™ decoder or the STA660 DAB/DRM decoder, the TDA7707 allows to realize complete, multi-standard receiver solution, with low bill of material, high performance and automotive grade quality and reliability.

TDA7707 is pin-to-pin compatible with ST's single-channel tuner TDA7708, allowing efficient design of scalable terrestrial radio-receiver platforms.
