SI2169-B40-GMR

Video Processing Overview

The Si2169-B40-GMR is a multimedia digital demodulator integrating DVB-T2, T2-Lite, 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 (1.14V to 1.30V) and VDD_VANA/VDD_VIO (3.00V to 3.60V). The device supports an input clock reference of 4MHz to 30MHz and utilizes a QFN-48 package measuring 7x7mm.

• Advanced Multimedia Set-Top Boxes (STB)
• PC-TV Accessories
• PVR, DVD, and Blu-Ray Disc Recorders

Video Processing Procurement Notes

Verify the manufacturer origin carefully, as the datasheet identifies Silicon Laboratories while the model suffix indicates Skyworks Solutions Inc. Confirm RoHS compliance and Pb-free status against current regulatory requirements. Ensure the specific B40 variant matches the required pinout and API compatibility with existing designs referencing older Si2169 models.

Video Processing Selection Notes

Select this component for hybrid TV front-end solutions requiring support for terrestrial, cable, and satellite standards simultaneously. It is suitable for applications needing fast lock times and autonomous signal acquisition. Verify that the system design accommodates the differential IF inputs for T/C tuners and ZIF I/Q inputs for satellite tuners.

Video Processing Part Context

This part belongs to the Si2169 family of multimedia digital TV demodulators. It is designed to minimize front-end complexity by integrating multiple demodulation architectures. The device offers firmware control for upgradeability and maintains pin-to-pin and API compatibility with previous generations like the Si2166/67/68B.

Video Processing Replacement Considerations

The datasheet confirms pin-to-pin and API compatibility with the standard Si2169 and variants including Si2166, Si2167, Si2168B, Si2164, Si2162, and Si2160.
