SI2168-B40-GMR

Video Processing Overview

The Si2168-B40-GMR is a digital TV demodulator integrating DVB-T2, DVB-T, and DVB-C standards. It operates with two power supplies: VDD_VCORE (1.14–1.30 V) and VDD_VANA/VDD_VIO (3.00–3.60 V). Total power consumption reaches up to 420 mW for DVB-T2, 190 mW for DVB-T, and 180 mW for DVB-C under maximum load conditions. The device supports input clock references from 4 to 30 MHz and crystal frequencies of 16 to 30 MHz. It utilizes a 7x7 mm QFN-48 pin package.

Video Processing Feature Summary

• Integrates DVB-T2/T/C demodulators with LDPC + BCH FEC decoding
• Supports bandwidths of 1.7, 5, 6, 7, or 8 MHz including extended bandwidth
• Features on-chip blind scanning algorithm for DVB-C standards
• Provides flexible transport stream interface compatible with MPEG decoders

Video Processing Applications

• iDTV set-top boxes
• Advanced STB systems
• PC-TV accessories
• PVR and disc recorders

Video Processing Procurement Notes

Verify the specific ordering suffix '-GMR' against manufacturer documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with host I2C interfaces and GPIO configurations required by the target application design.

Video Processing Selection Notes

Select this component for applications requiring integrated support for legacy cable and modern terrestrial standards. Consider the 7x7 mm QFN-48 footprint for space-constrained designs. Verify thermal resistance requirements based on the PCB layer count, as dissipation varies between 2-layer and 4-layer boards.

Video Processing Part Context

This part belongs to the Silicon Labs Si2168 series of mixed-signal CMOS demodulators. It offers pin-to-pin and software compatibility with other variants in the family, such as the Si2164/62/60/66B/67B/69B, facilitating design reuse across different product generations.

Video Processing Replacement Considerations

Compatible replacements include other members of the Si2168 family, specifically the Si2168-B30 or Si2168-B60, provided they meet the specific frequency and standard requirements.
