Product Summary

The TEF6730HW/v1 is a car radio tuner front-end for digital-IF reception. The TEF6730HW/v1 is especially designed for co-operation with digital-IF DSP back-ends of the SAF773x and SAF778x families. The FM tuner features single conversion to IF = 10.7 MHz and integrated image rejection; capable for FM 65 MHz to 108 MHz and weather band reception. The AM tuner features single conversion to IF = 10.7 MHz with an integrated AM front-end, capable for LW, MW and full SW reception. The TEF6730HW/v1 can be controlled via the fast-mode I2C-bus (400 kHz) and includes autonomous tuning functions for easy control. No manual alignments are required.
