SI2167-B22-GM

Video Processing Overview

The Si2167-B22 is a CMOS system-on-chip integrating DVB-T, DVB-C, DVB-S, and DVB-S2 digital demodulators. It supports terrestrial, cable, and satellite TV standards with an IF input for standard (36 MHz) or low-IF signals. The device features three ADCs with independent inputs, GPIOs for tuner control, and a programmable Transport Stream interface. Power supplies are 1.2 V and 3.3 V. Total power consumption ranges from 180 mW to 465 mW depending on the mode. It operates within a temperature range of -10 °C to 75 °C.

Video Processing Procurement Notes

Verify that the specific part number matches the required package type and RoHS compliance status. Confirm that the operating voltage requirements align with your system design. Ensure firmware upgradeability needs are met by the device's architecture. Check thermal resistance specifications against your PCB layer count to ensure proper heat dissipation during operation.

Video Processing Selection Notes

Select this component when a unified solution for multiple broadcast standards is required. It is suitable for designs needing direct integration with hybrid tuners. Consider its low power consumption and small footprint for portable or space-constrained applications. Verify compatibility with existing MPEG decoder architectures before finalizing the selection.

Video Processing Part Context

This device belongs to Skyworks' digital TV demodulator family. It serves as an evolution of earlier models like the Si2169/68/67-A series. The chip consolidates functions previously handled by separate components. It is designed to reduce front-end complexity while maintaining high reception performance across various media types.

Video Processing Replacement Considerations

The Si2167-B22 offers pin-to-pin and API compatibility with the Si2164, Si2169, Si2168, and Si2166 models. These parts can be considered for direct replacement in existing designs without requiring significant schematic changes.
