Procurement Notes
Verify component status carefully as this part is marked as obsolete or end-of-life. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCI-based designs before procurement. Check for RoHS3 compliance and moisture sensitivity level requirements during storage and handling.
Selection Notes
Select this component for legacy PCI-based video decoding architectures requiring support for multiple analog video standards. Consider the 144-TQFP package constraints for PCB layout. Evaluate power supply requirements against the specified 1.2V to 3.3V range. Assess obsolescence risks and potential need for long-term supply agreements due to discontinued status.
Part Context
This part belongs to the Techwell series of video processors. It serves as a specialized decoder for converting analog video signals into digital formats compatible with PCI interfaces. The component is distinct from general-purpose video processors by its specific focus on standard decoding and PCI connectivity.
Replacement Considerations
No verified public substitute part numbers are available for this obsolete component. Designers should evaluate newer video decoder families from Renesas or other manufacturers that offer modern interfaces such as PCIe or USB instead of legacy PCI.
