SI2177-A30-GMR

Video Processing Overview

The Skyworks SI2177-A30-GMR is a universal hybrid TV tuner integrating digital and analog reception capabilities for terrestrial and cable standards. It features an integrated PAL/SECAM/NTSC analog demodulator and supports DVB-T2, ATSC, and ISDB formats. The device utilizes a low-IF architecture with a fifth-generation RF front-end, eliminating the need for external baluns, SAW filters, or inductive power supply filtering. It operates on 1.8 V and 3.3 V supplies, consuming 496 mW in ATV mode. The component provides superior video SNR, high immunity to Wi-Fi and LTE interference, and industry-leading phase noise performance within a 4x4 mm, 28-pin QFN package.

Video Processing Feature Summary

• Integrates digital and analog TV reception with no external balun, SAW filters, or wire-wound inductors required.
• Delivers high immunity to Wi-Fi and LTE interference through a harmonic rejection mixer.
• Provides flexible output interfaces including combined ALIF/DLIF to SoC or optional DLIF to external demodulators.
• Includes an integrated power-on reset circuit and single-supply option for 3.3 V-only operation.

Video Processing Applications

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

Video Processing Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel configuration. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding material or assembly updates. Ensure the selected variant aligns with the intended supply voltage requirements and interface compatibility.

Video Processing Selection Notes

Select this component when minimizing bill of materials is critical due to its fully integrated RF front-end and absence of external passive components. Consider it for designs requiring robust interference immunity against Wi-Fi and LTE signals without additional filtering. Evaluate its suitability for applications needing both digital and analog demodulation within a compact footprint.

Video Processing Part Context

The Si2177 belongs to Skyworks' fourth-generation tuner family, offering pin- and API-compatibility with previous models to reduce development effort. It represents a shift toward highly integrated silicon solutions that replace discrete MOPLL-based tuners, providing optimized system performance and lower power consumption while maintaining global standard support.

Video Processing Replacement Considerations

The Si2128 series offers pin and API compatibility as a predecessor. Verify functional equivalence and interface alignment before substitution. No other direct public substitutes are confirmed in official documentation.
