SI2111-A10-GM

Video Processing Overview

The Skyworks Solutions Inc. SI2111-A10-GM is a digital TV receiver integrating a tuner and DVB-T demodulator in a single CMOS IC. It operates within a 42–870 MHz frequency range with a maximum gain noise figure of 4.0 dB. The device supports DVB-T modes including 8K, 64-QAM, and 2/3CR, achieving -84 dBm sensitivity under Quasi Error Free conditions. Power consumption reaches 1.1 W in DVB-T mode using 1.8 V and 3.3 V supplies. It features a 7x7 mm, 48-pin QFN package.

Video Processing Feature Summary

• Integrates complete digital TV tuner and DVB-T demodulator into a single monolithic CMOS mixed-signal IC
• Utilizes third-generation digital low-IF architecture for superior reception without external LNAs or SAW filters
• Includes on-chip Blindscan and Blindlock scanning algorithms for optimized channel acquisition
• Provides flexible serial or parallel transport stream output compatible with MPEG decoders

Video Processing Applications

• Digital terrestrial or cable set-top boxes (STB)
• Digital personal video recorders (PVR) and DVD recorders
• Digital PC TV cards and USB dongles
• Digital full-NIM tuner modules

Video Processing Procurement Notes

Verify the manufacturer designation carefully as sources attribute this component to Silicon Laboratories despite the prompt specifying Skyworks Solutions Inc. Confirm the specific suffix matches the required DVB-T functionality, as other variants exist for different standards. Ensure compatibility with the 7x7 mm QFN-48 footprint during procurement planning.

Video Processing Selection Notes

Select this component when minimizing bill of materials is critical due to its high integration level eliminating external filtering requirements. It is suitable for applications requiring robust performance in crowded spectrum environments. Verify that the system design accommodates the specified 1.8 V and 3.3 V power supply rails and the 24 MHz crystal reference requirement.

Video Processing Part Context

This part belongs to the Si2115/13/11 family of digital TV receivers designed by Silicon Laboratories. The family integrates tuner and demodulator functions to reduce PCB footprint. The Si2111 variant specifically targets DVB-T applications, distinguishing it from models supporting DVB-C or both standards.
