Manufacturer: Texas Instruments

Overview: .ti.

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.

A 15-bit programmable counter and reference divider are controlled by inter-integrated circuit (I2C) bus protocol.
