TEA6848HL

The TEA6848HL is designed as one kind of new in car entertainment car radio tuner IC that provides the following functions:(1)AM double conversion receiver for LW, MW and SW (31 m, 41 m and 49 m bands) with IF1 = 10.7 MHz and IF2 = 450 kHz; (2)FM double conversion receiver with integrated image rejection for IF1 and for IF2 capable of selecting US FM, US weather, Europe FM, East Europe FM and Japan FM bands; fully integrated dynamic selectivity at 450 kHz FM IF2; FM demodulator with dynamic threshold extension; center frequency alignment of IF2 selectivity via the I2C-bus; (3)The tuning system includes VCO, crystal oscillator and PLL synthesizer on one chip.

Features of the TEA6848HL are:(1)AM mixer 1 for conversion of AM RF to AM IF1 of 10.7 MHz; (2)LC tuner oscillator providing mixer frequencies for FM mixer and AM mixer 1; (3)AM mixer 2 for conversion of AM IF1 to AM IF2 of 450 kHz; (4)Fast synthesizer PLL tuning system with local control for inaudible RDS updating; (5)FM IF linear amplifier with high dynamic input range; (6)FM mixer 2 for conversion of FM IF1 to FM IF2 of 450 kHz with inherent image rejection; (7)Digital alignment circuit for bus controlled matching of oscillator tuning voltage to FM antenna tank circuit tuning voltage.etc. If you want to know more information such as the electrical characteristics about the TEA6848HL, please download the datasheet in www.seekic.com or www.chinaicmart.com.
