SI2111-A10-GMR

Video Processing Overview

The SI2111-A10-GMR is a digital TV receiver integrating a tuner and DVB-T demodulator. It operates within a 42–870 MHz frequency range with a 4.0 dB noise figure. Power supplies are 1.8 V and 3.3 V, consuming 1.1 W in DVB-T mode. Sensitivity reaches -84 dBm at Quasi Error Free conditions. The component utilizes a 7x7 mm, 48-pin QFN package.

Video Processing Feature Summary

• Integrates complete digital TV tuner and DVB-T demodulator into a single CMOS mixed-signal IC.
• Eliminates need for external LNAs, tracking filters, or SAW filters through on-chip integration.
• Includes on-chip Blindscan and Blindlock scanning algorithms for optimized reception.
• Provides flexible serial or parallel Transport Stream output compatible with MPEG decoders.

Video Processing Applications

• Digital terrestrial set-top boxes
• Digital PVR and DVD recorders
• Digital PC TV cards and USB dongles

Video Processing Procurement Notes

Verify the specific Si2111 variant supports only DVB-T, as other models in this family support DVB-C. Confirm RoHS compliance status and check for End-of-Life notifications from Silicon Laboratories prior to finalizing procurement plans.

Video Processing Selection Notes

Select this component when a highly integrated solution minimizing external components is required. Ensure the application strictly requires DVB-T standards, as DVB-C capabilities are not included in this specific part number compared to the Si2115 model.

Video Processing Part Context

This device belongs to the Si2115/13/11 family of digital TV receivers. It shares the same 7x7 mm QFN-48 package and core architecture but differs in supported broadcast standards. The Si2111 specifically targets DVB-T applications without DVB-C functionality.

Video Processing Replacement Considerations

Si2115-A10-GMR (supports both DVB-T and DVB-C). Si2113-A10-GMR (supports DVB-C only).
