SI2168-A20-GM

Video Processing Overview

The Skyworks SI2168-A20-GM is a digital demodulator integrating DVB-T2, DVB-T, and DVB-C standards into a single CMOS 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 accepts an input clock reference of 4 to 30 MHz and supports crystal frequencies from 16 to 30 MHz. Total power consumption ranges up to 420 mW for DVB-T2 and 190 mW for DVB-T. It utilizes a 7x7 mm QFN-48 package.

Video Processing Feature Summary

• Supports bandwidths of 1.7, 5, 6, 7, or 8 MHz including extended bandwidths
• Features on-chip blind scanning and lock algorithms for DVB-C standards
• Provides flexible transport stream interface compatible with MPEG decoders

Video Processing Applications

• Integrated digital TV (iDTV) onboard modules
• Network Interface Modules (NIM)
• Advanced set-top boxes (STB)
• PC-TV accessories
• PVR, DVD, and Blu-Ray disc recorders

Video Processing Procurement Notes

Verify the manufacturer origin as Silicon Laboratories based on the provided datasheet copyright. Confirm RoHS compliance and Pb-free status. Ensure the specific A20 suffix matches the required DVB-T2/T/C functionality. Check for pin-to-pin compatibility requirements with Si2167 or Si2169 if applicable to the design.

Video Processing Selection Notes

Select this component for applications requiring support for terrestrial and legacy cable TV standards in a mixed-signal environment. Consider the 7x7 mm QFN-48 package size for space-constrained designs. Evaluate power consumption limits against thermal resistance specifications for 2-layer or 4-layer PCB implementations.

Video Processing Part Context

This part belongs to the Si2168 series of high-definition television system-on-chip devices. It is designed to minimize front-end complexity by integrating demodulation functions directly onto the silicon die. The architecture leverages proven digital demodulation techniques to achieve robust signal reception performance.

Video Processing Replacement Considerations

The datasheet indicates pin-to-pin and software compatibility with the Si2169, which serves as a superset supporting additional standards like DVB-S/S2.
