5 V Mixer/oscillator-pll Synthesizers For Hyperband Tuners

The TDA6404 TDA6405 and TDA6405A are programmable 2-band mixer/oscillator-PLL synthesizers intended for VHF/UHF and hyperband Tuners (see Fig.1). The devices include two double balanced mixers and two Oscillators for the VHF and UHF band, an IF Amplifier and a PLL synthesizer. With proper Oscillator application and by using a switchable inductor to split the VHF band into two sub-bands (the full VHF/UHF and hyperband) the TV bands CAN be covered. Two pins are available between the mixer output and the IF Amplifier input to enable IF filtering for improved signal handling. Three PNP ports are provided for band switching. Band selection is made according to the band Switch bits VHFL, VHFH and UHF. By NXP Semiconductors
