SI21672-B22-GM

Video Processing Overview

The SI21672-B22-GM is a dual digital TV demodulator manufactured by Skyworks Solutions Inc. It integrates DVB-T, DVB-C, DVB-S, and DVB-S2 (AMC-compliant) demodulation capabilities into a single CMOS chip. The device operates on a 1.2 V core voltage and a 3.3 V I/O voltage, with a maximum supply voltage of 3.6 V and a minimum of 1.14 V. It supports QPSK modulation formats and functions within a frequency range of 36 MHz. The component utilizes an I2C interface for control and is housed in a 68-pin QFN package measuring 8x8 mm.

Video Processing Feature Summary

• Integrates dual digital TV demodulators supporting terrestrial, cable, and satellite standards including DVB-T, DVB-C, DVB-S, and DVB-S2.

Video Processing Applications

• Digital television receivers
• Set-top boxes
• Television tuners

Video Processing Procurement Notes

Verify the specific suffix GMR against the base part number to confirm packaging variations such as reel or cut tape options. Confirm current availability status as distribution channels may indicate limited stock or end-of-life conditions. Ensure compatibility with existing I2C bus configurations and GPIO requirements before procurement.

Video Processing Selection Notes

Select this component when dual demodulation functionality is required for mixed DVB-T/C/S/S2 environments. Verify that the system design accommodates the 68-QFN thermal pad requirements and the specific 1.2V/3.3V power domain separation. Ensure the application does not require analog output stages, as this is a pure digital demodulator.

Video Processing Part Context

This part belongs to the Si2167 family of integrated circuit demodulators designed for consumer electronics. It serves as a high-performance solution for multi-standard digital video reception, replacing discrete demodulator solutions with a single-chip CMOS implementation.
