TDA5630BT - 9 V VHF and UHF mixer/oscillator for TV and VCR cable tuners

General Description

The TDA5630BT is a monolithic integrated circuit that performs VHF and UHF mixer/oscillator functions in TV and VCR cable tuners.

With a proper oscillator application and by using a switchable inductor to split the VHF band into two sub-bands, the full VHF/UHF TV bands can be covered.

Key Features

  • Balanced mixer with a common emitter input for band A (single input).
  • 2-pin oscillator for band A.
  • Balanced mixer with a common base input for band C.
  • 3-pin oscillator for band C.
  • Local oscillator buffer output for external prescaler.
  • SAW filter preamplifier with a low output impedance to drive a SAW filter.
  • Band gap voltage stabilizer for oscillator stability.
  • Electronic band switch.
