Low IF tuner high performance one-chip

General description   TEF6686HN

The  Low IF Tuner HIgh performance One chips, TEF6686 and TEF6688, are single-chip

radio ICs including an AM/FM radio tuner and software-defined radio signal processing.

Features and benefits   TEF6686HN

 Alignment free digital receiver including tuner and software-defined radio processing

 Command based high-level user interface combining high control flexibility with ease

of control 

 Read information with device and tuning status, reception quality and RDS data

 FM receiver with a tuning range of 65 MHz to 108 MHz covering Eastern Europe

(OIRT), Japan, Europe and US bands

 AM receiver covering LW, MW and full SW

 Fully integrated tuning system with low phase noise and fast tuning

 FM LNA with AGC 

 State-of-the art FM Improved Multipath Suppression

 FM Channel Equalization

 Soft Mute on Modulation

 Stereo High Blend

 FM mixer for frequency conversion to a low IF complex signal (AM SW)

 AM LNA with AGC, matching active and passive antenna applications

 AM mixer for frequency conversion to a low IF complex signal

The TEF668X is a single tuner AM/FM receiver for automotive applications and supports

analog AM/FM and HD/DRM reception (HD/DRM is supported in TEF6688 only).

Additionally, due to a common technology platform, the TEF668X can be combined with

TEF701X, SAF775X and SAF360X for optimal system application through common

crystal oscillator sharing.
