SN761683BDAR

Video Processing Overview

The SN761683BDAR is a synthesized TV tuner IC manufactured by Texas Instruments, designed for television tuning systems. It integrates a phase-locked loop (PLL) synthesizer, three-band local oscillator and mixer, a 30-V output tuning amplifier, and four NPN band-switch drivers. The device operates on a 5-V power supply and features a 32-pin Thin Shrink Small-Outline Package (TSSOP). It supports an Inter-Integrated Circuit (I2C) bus protocol for control, utilizing a 15-bit programmable counter and reference divider with selectable ratios of 512, 640, or 1024.
