TV / VCR调谐器IC TV/VCR TUNER IC
description
SN761672A is a single chip synthesized tuner IC designed for TV/VCR tuning systems. The circuit consists of a PLL synthesizer, 3-band local oscillators and mixer, a 30-V output tuning amplifier, and four NPN band switch drivers. It is available in a small package outline. The 15-bit programmable counter and reference divider is controlled by I2C bus protocol. Tuning step frequency is selectable by this reference-divider ratio for a 4-MHz crystal oscillator.
