Video Processing Procurement Notes

Verify the specific B22 suffix against official Skyworks documentation to confirm pinout and feature alignment. Confirm RoHS compliance status through current datasheets. Check for API compatibility requirements if replacing legacy Si2164 or Si2169 components in existing designs.

Video Processing Selection Notes

Select this component for applications requiring broad satellite standard support including DVB-S2 CCM profiles. Ensure system design accommodates the dual power supply rails of 1.2 V and 3.3 V. Verify that the host processor supports the required I2C master and host interfaces for firmware control and configuration.

Video Processing Part Context

The Si2166-B22 belongs to the Si2166 family of satellite demodulators. It maintains pin-to-pin and API compatibility with the Si2164, Si2169, Si2168, and Si2167 models. This allows for straightforward migration in designs previously utilizing those specific Skyworks solutions.

Video Processing Replacement Considerations

Officially documented substitutes include Si2164, Si2169, Si2168, and Si2167 due to confirmed pin-to-pin and API compatibility.
