SN761683DAR

Video Processing Overview

The SN761683DAR is a synthesized TV tuner IC manufactured by Texas Instruments. It integrates a phase-locked loop (PLL) synthesizer, three-band local oscillator and mixer, a 30-V tuning-voltage output amplifier, and four NPN band-switch drivers. The device operates on a 5-V power supply and features an Inter-Integrated Circuit (I2C) bus protocol for control. It utilizes a 15-bit programmable counter with reference divider ratios of 512, 640, or 1024. The component is housed in a 32-pin Thin Shrink Small-Outline Package (TSSOP).

Video Processing Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead finish details against current manufacturer documentation. Ensure the operating temperature range requirements align with the specified industrial limits. Validate pinout compatibility during integration planning.

Video Processing Selection Notes

Select this component for applications requiring integrated RF synthesis and mixing functions. Consider the 32-pin TSSOP package constraints for board layout. Evaluate the I2C interface requirements for system controller compatibility. Assess the need for external components based on the reference measurement circuit specifications provided in the datasheet.

Video Processing Part Context

This part belongs to the SN761683B family of TV tuner ICs from Texas Instruments. It is designed specifically for television tuning systems.
