TA1303AFN

The TA1303AFN is a single chip which integrates a PLL and a MIX-OSC for VHF,CATV and UHF band.The control data conforms to 3 wire bus and I2C bus formats.Bus-SW can be used to easily switch for easy tuner system set-up.

Features of the TA1303AFN are:(1)VHF-CATV band is mixer and oscillator;(2)UHF bands is mixer and oscillator;(3)built-in IF amplifier;(4)single IF output terminal;(5)standard bi-directional I2C bus format control;(6)3-wire bus format control;(7)18-bit and 19-bit automatical discrimination circuit (when 3-wire bus selected);(8)tuning amplifier;(9)4-bit bandswitch drive transistor;(10)5-levels A/D convertor (when I2C bus selected);(11)frequency step is 31.5kHz,50kHz, and 62.5kHz (at 4MHz X'tal used);(12)4 programmable chip address(when I2C bus selected);(12)power on resist circuit;(14)1/4 prescaler.
