TDA5744 Datasheet (NXP) - Low power mixers/oscillators for hyperband tuners

TDA5744, Low power mixers/oscillators for hyperband tuners

The TDA5744 and TDA5745 are 2-band mixers/oscillators intended for VHF/UHF and hyperband tuners (see Fig.1).

The Integrated Circuits (ICs) include two double balanced mixers and two oscillators, for the VHF and UHF band, and an IF amplifier.

With proper oscillator application and by using a switchab
