描述 Description

The TDA7707 is a single chip fully-CMOS quad-band, dual-channel tuner aimed at receivers for analog and digital terrestrial radio broadcasting.

When paired to STMicroelectronics’s STA680 or STA660 digital decoder ICs, the TDA7707 constitutes a complete optimized RF and baseband AM/FM/HD/DAB/DRM solution for automotive grade receivers and other applications.

The TDA7707 combines state-of-art performance with minimum external component count, making it therefore ideal for integration into car radios and other AM/FM/HD/DAB/DRM devices with challenging performance, quality, reliability and, last but not least, cost requirements.

Combining TDA7707 with either STA680 or STA660 results in a complete, multi-standard receiver solution, with low bill of material, high performance and real automotive grade quality and reliability.

Two device versions are available, differing only by the ROM content: the TDA7707EB requires a small FW code to be downloaded for booting the IC, thus making it especially suited to systems whose microcontroller has limited code storage capability.
