General Description

The TDA5636B and TDA5637B 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 design an economical and physically small 3-band tuner.

Overview

INTEGRATED CIRCUITS DATA SHEET TDA5636B; TDA5637B 9 V VHF hyperband and UHF mixer/oscillator for TV and VCR 3-band tuners Product specification Supersedes data of 1995 August 01 File under Integrated Circuits, IC02 1996.

Key Features

  • Balanced mixer with a common emitter input for band A (single input).
  • 2-pin oscillator for bands A and B.
  • Balanced mixer with a common base input for bands B and C (balanced input).
  • 4-pin oscillator for band C.
  • Local oscillator buffer output for external prescaler.
  • SAW filter preamplifier with a low output impedance to drive the SAW filter directly.
  • Band gap voltage stabilizer for oscillator stability.
  • Electronic band switc.
