SI2177-A30-GM

Video Processing Overview

The Si2177-A30-GM is a worldwide hybrid TV tuner with an integrated analog demodulator supporting terrestrial and cable standards. It features a digital low-IF architecture with a fifth-generation RF front-end, delivering superior second-order distortion performance and industry-leading phase noise. The device integrates LNAs and tracking filters, eliminating the need for external baluns or SAW filters. It supports single or dual supply voltages (3.3 V and 1.8 V) and includes an integrated power-on reset circuit. The component operates within a temperature range of -40°C to +85°C and is housed in a 4x4 mm QFN-28 package.

Video Processing Feature Summary

• Universal hybrid reception capability for global terrestrial and cable TV standards
• Integrated analog demodulator for NTSC, PAL, and SECAM formats
• High immunity to Wi-Fi and LTE interference via harmonic rejection mixer
• Lowest bill-of-materials design through complete internal integration of RF components

Video Processing Applications

• Hybrid 1/2-NIM, 3/4-NIM, and full-NIM tuner modules
• Integrated Digital Television (iDTV)
• Hybrid terrestrial and cable set-top boxes
• Hybrid PVR, DVD, and Blu-Ray disc recorders
• PC-TV accessories

Video Processing Procurement Notes

Verify the specific A30 suffix against the manufacturer's current documentation to confirm pinout and API compatibility requirements. Confirm that the 4x4 mm QFN-28 package dimensions align with your PCB footprint specifications. Ensure your system design accommodates the required 3.3 V and 1.8 V power rails or the single-supply option as defined in the electrical characteristics. Cross-reference the RoHS compliance status with your environmental regulations.

Video Processing Selection Notes

Select this component when a unified solution for both digital and analog TV reception is required without external filtering components. It is suitable for designs prioritizing minimal board space and reduced component count due to its high level of integration. Consider this part for applications demanding high immunity to adjacent band interference from wireless networks. Verify that the supported standards match the target regional broadcast requirements.

Video Processing Part Context

The Si2177 belongs to Skyworks' family of hybrid TV tuners, designed to replace discrete MOPLL-based solutions. It maintains pin and API compatibility with previous generations to minimize customer development effort. The device utilizes standard CMOS process technology and offers flexible output interfaces for connection to system-on-chip processors or external demodulators.

Video Processing Replacement Considerations

Check Skyworks documentation for direct pin-compatible upgrades within the Si217x series. Verify if alternative models offer different supply voltage configurations or enhanced interference rejection metrics. Ensure any substitute maintains support for the specific digital standards required by your application.
