TDA6405 Datasheet (NXP) - 5 V mixer/oscillator-PLL synthesizers for hyperband tuners

TDA6405, 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.
