SI2167-C55-GM

Video Processing Overview

The SI2167-C55-GM is a single-chip digital TV tuner and demodulator manufactured by Skyworks Solutions Inc. It supports DVB-T, DVB-T2, ISDB-T, and DTMB terrestrial broadcast standards. The device integrates a high-performance analog-to-digital converter (ADC) and a digital baseband processor to deliver robust signal reception in compact form factors. Designed for low power consumption, it utilizes an I²C interface for control and configuration. The component is housed in a 48-lead QFN package measuring 7x7 mm, suitable for space-constrained applications such as set-top boxes, monitors, and portable devices.

Video Processing Feature Summary

• Integrated support for multiple global terrestrial digital television standards including DVB-T/T2, ISDB-T, and DTMB within a single silicon die.
• Combines a high-sensitivity analog front-end with a digital baseband processor to enable direct digitization of RF signals without external IF stages.
• Utilizes a standard I²C serial interface for simplified system integration and control logic connectivity.

Video Processing Applications

• Digital video broadcasting receivers and set-top boxes
• Flat-panel televisions and monitors with integrated tuners
• Portable media players and mobile digital TV devices

Video Processing Procurement Notes

Verify the specific suffix 'C55' against official Skyworks documentation to confirm regional standard support and pinout compatibility. Ensure the 'GM' designation matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity.

Video Processing Selection Notes

Select this component when designing systems requiring multi-standard terrestrial TV reception in a minimal footprint. Evaluate the I²C interface requirements against the host microcontroller's capabilities. Consider the thermal performance of the 48-QFN package relative to the enclosure design. Confirm that the target market regulations align with the supported broadcast standards defined in the datasheet.

Video Processing Part Context

Skyworks Solutions acquired Silicon Laboratories' wireless connectivity and IoT business unit, which included the Si21xx series of tuners. Consequently, the SI2167 series is now marketed under the Skyworks brand while retaining its original technical specifications and functionality. This transition maintains continuity for existing designs while updating the manufacturer attribution in supply chain documentation.

Video Processing Replacement Considerations

Consult official Skyworks substitution guides for verified alternatives. Generic cross-references may not guarantee identical electrical characteristics or pin compatibility. Verify any substitute part against the specific C55 variant requirements before implementation.
