TDA5637 Datasheet (NXP) - 9 V VHF/ hyperband and UHF mixers- oscillators for TV and VCR 3-band tuners

TDA5637, 9 V VHF/ hyperband and UHF mixers- oscillators for TV and VCR 3-band tuners

The TDA5636 and TDA5637 are monolithic integrated circuits that perform the mixer/oscillator functions for bands A, B and C in TV and VCR tuners.

These low-power mixer/oscillators require a power supply of 9 V and are available in a very small package.

The devices give the designer the capability to
