SN761683B - TV TUNER

General Description

The SN761683B is a synthesized tuner IC designed for TV tuning systems.

The circuit consists of a phase-locked loop (PLL) synthesizer, three-band local oscillator and mixer, 30-V output tuning amplifier, and four NPN band-switch drivers, and is available in a small-outline package.

Key Features

  • Single-Chip Mixer/Oscillator and Phase-Locked Loop (PLL) Synthesizer.
  • Three-Band Local Oscillator and Mixer.
  • Inter-Integrated Circuit (I2C) Bus Protocol (Bidirectional Data Transmission).
  • 30-V Tuning-Voltage Output.
  • Four NPN-Type Band-Switch (BS) Drivers.
  • Programmable Reference Divider Ratio (512, 640, or 1024).
  • 5-V Power Supply.
  • 32-Pin Thin Shrink Small-Outline Package (TSSOP).
