SI2169-A20-GMR

Video Processing Overview

The Si2169-A20-GMR is a multimedia digital demodulator integrating DVB-T2, DVB-T, DVB-C, DVB-S, and DVB-S2 standards into a single CMOS mixed-signal die. It operates with two power supplies: VDD_VCORE (1.14 to 1.30 V) and VDD_VANA/VDD_VIO (3.00 to 3.60 V). The device supports an input clock reference of 4 to 30 MHz and accepts standard IF or low-IF inputs for terrestrial/cable applications. Total power consumption varies by mode, ranging from 190 mW for DVB-T2/DVB-C to 465 mW for DVB-S2.

Video Processing Feature Summary

• Integrates DVB-T2, DVB-T, DVB-C, DVB-S, and DVB-S2 digital demodulators within a single advanced CMOS mixed-signal die.
• Features independent differential IF inputs for terrestrial/cable tuners and differential ZIF I/Q inputs for satellite tuners.
• Includes an on-chip blind scanning algorithm for DVB-S/S2 and DVB-C standards alongside DiSEqC 2.0 LNB interface support.
• Provides a programmable transport stream interface compatible with MPEG decoders and conditional access modules.

Video Processing Applications

• iDTV set-top boxes utilizing onboard or NIM configurations
• Advanced multimedia STB platforms
• PC-TV accessories
• PVR, DVD, and Blu-Ray disc recorders

Video Processing Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm package type and compliance status. Confirm that the component matches the required pinout compatibility with existing designs referencing Si2167 or Si2168 architectures. Ensure supply chain sources provide valid traceability for RoHS and Pb-free manufacturing standards.

Video Processing Selection Notes

Select this component when a unified solution for terrestrial, cable, and satellite reception is required. The integrated architecture minimizes front-end design complexity compared to discrete demodulator implementations. Verify that the target application can accommodate the 7x7 mm QFN-48 package dimensions and thermal requirements.
