Product overview
Description
The TDA7708S is a single chip fully-CMOS AM/FM tuner aimed at receivers for terrestrial radio broadcasting.
The TDA7708S combines state-of-art performance with minimum external component count, making it therefore ideal for integration into car radios and other radio devices with challenging performance, quality, reliability and, last but not least, cost requirements.
Such a low external component count is made possible by cutting-edge circuit and implementation techniques that overcome the major challenges affecting both very-low and zero IF receivers.
The TDA7708S features multiple front-end low-noise amplifiers (LNAs) to cover AM LW/MW/SW bands, and the entire FM band, with advanced automatic gain control (AGC) amplifier and mixer stages.
After on-chip IF filtering, the TDA7708S digitizes the signal with a very high dynamic range ADC; it processes the complex phase-quadrature baseband signal allowing applications like multipath noise mitigation, and integrated RDS decoding.
The TDA7708S furthermore integrates the HD-Radio™ channel filtering.
Besides providing optimal AM/FM quality reception, the TDA7708S makes it the ideal solution to realize a complete HD-Radio™ receiver solution (in combination with the external STA680D HD-Radio™ decoder), with a low bill of material, high performance and real automotive grade quality and reliability.
The TDA7708SCB requires a very small FW code to be downloaded for booting the IC, thus making it especially suited to systems whose microcontroller has limited code storage capability.
