Description

The TDA7708 is a single chip fully-CMOS AM/FM tuner aimed at receivers for

terrestrial radio broadcasting.

The TDA7708 is a complete integrated and optimized RF tuner for AM/FM reception.

It allows the implementation of AM/FM solution (and also HD-Radio™ with external

STMicroelectronics's STA680 co-processor) for automotive grade receivers and other

applications.

The TDA7708 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 verylow

and zero IF receivers.

The TDA7708 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 TDA7708 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 TDA7708 furthermore integrates the HD-Radio™ channel filtering.

Besides providing optimal AM/FM quality reception, the TDA7708 makes it the ideal

solution to realize a complete HD-Radio™ receiver solution (in combination with the

external STA680 HD-Radio™ decoder) or a DRM receiver (paired to the

STA660DRM), with a low bill of material, high performance and real automotive grade

quality and reliability.
