SI21662-C55-GM

Video Processing Overview

The SI21662-C55-GM is a dual universal digital TV demodulator manufactured by Skyworks Solutions Inc. It supports DVB-S/S2, DVB-C/C2, and DVB-T/T2 standards within a single integrated circuit. The device operates on a 3.3V supply voltage and utilizes an I2C interface for control. It is housed in a compact QFN-68 package measuring 8x8mm. This component is designed for high-performance reception of satellite, cable, and terrestrial signals.

Video Processing Feature Summary

• Dual universal demodulation capability supporting multiple broadcast standards
• Integrated silicon tuner interface for simplified system design
• Low power consumption optimized for portable and fixed applications

Video Processing Applications

• Satellite set-top boxes
• Cable television receivers
• Terrestrial digital TV tuners
• All-in-one digital TV receivers

Video Processing Procurement Notes

Verify the specific suffix C55 to confirm the supported modulation formats and frequency ranges against your system requirements. Confirm end-of-life status with the manufacturer or authorized distributors as availability may be limited. Ensure I2C address configurations match your host controller design before finalizing procurement.

Video Processing Selection Notes

Select this component when a single chip solution is required for multi-standard digital TV reception. Compare pin compatibility with previous generation Skyworks demodulators if upgrading existing designs. Verify that the QFN-68 thermal pad soldering process meets your manufacturing capabilities for reliable heat dissipation.

Video Processing Part Context

This part belongs to the Skyworks SI216xx series of highly integrated video demodulators. These components are widely used in consumer electronics to reduce board space and simplify RF front-end designs by combining demodulation and tuner control functions into one package.

Video Processing Replacement Considerations

Check for direct pin-to-pin replacements within the SI216xx family such as the SI21662-D60-GM or SI21662-B22-GM. Verify that alternative parts support the same DVB standards and operate at the same supply voltage levels.
