Procurement Notes
The IDT821034DN is listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life status updates. Ensure compliance with RoHS non-compliance status if required for specific environmental regulations. Confirm package integrity and moisture sensitivity level (MSL 3) handling procedures upon receipt.
Selection Notes
Select this component for applications requiring a quad-channel PCM codec with integrated SLIC functionality. It is suitable for designs needing software-configurable companding and flexible time-slot assignment. Verify that the 52-PQFP package fits the PCB layout constraints. Consider the discontinued status when planning long-term production runs.
Part Context
The IDT821034DN belongs to the IDT821034 family of PCM codecs. It is part of Renesas Electronics' portfolio of analog signal chain products. The device was originally developed by Integrated Device Technology (IDT) before its acquisition by Renesas. It serves as a specialized interface solution for telecommunications infrastructure.
Replacement Considerations
As the IDT821034DN is discontinued, verify compatible replacements through official Renesas documentation. Cross-reference pinouts and electrical specifications carefully. No direct substitute part numbers are confirmed in the provided public data.
