SN761688PWR

RF Mixers Overview

The SN761688PWR is a down converter IC designed for CATV applications, manufactured by Texas Instruments. It operates within a frequency range of 50MHz to 280MHz and requires a supply voltage between 4.5V and 5.5V. The device draws a supply current of 67mA and is housed in a 16-TSSOP package with a width of 4.40mm. It supports surface mount installation and functions as an RF mixer for signal conversion.

RF Mixers Feature Summary

• Integrated down converter functionality for radio frequency signal processing
• Designed specifically for cable television (CATV) system applications
• Surface mount compatible construction for automated assembly

RF Mixers Applications

• Cable television (CATV) down conversion systems
• RF mixer circuits in broadcast infrastructure
• Signal processing modules operating within the 50MHz to 280MHz band

RF Mixers Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the specific ordering suffix matches the required tape-and-reel configuration if applicable. Ensure the part number corresponds to the active or obsolete status indicated in official TI documentation before procurement. Cross-reference the 16-TSSOP package dimensions against PCB footprint requirements to guarantee mechanical compatibility.

RF Mixers Selection Notes

Select this component when a dedicated down converter is required for CATV frequencies between 50MHz and 280MHz. Consider the 4.5V to 5.5V supply voltage range and 67mA current consumption during power budgeting. Evaluate the 16-TSSOP package size for space constraints in surface mount designs. Verify that the application does not require digital conversion features, as this is an analog RF mixer solution.

RF Mixers Part Context

The SN761688 series belongs to Texas Instruments' portfolio of RF and microwave components. This specific model serves as a specialized integrated circuit for frequency translation tasks. It is distinct from logic shift registers or power management devices often listed in broader semiconductor catalogs. The PWR suffix denotes the TSSOP package variant within the SN761688 family.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The datasheet lists similar products such as the SN761681 TV tuner IC, but these serve different functions. No direct cross-reference substitutes are documented for this specific down converter model.
