Procurement Notes
This component is designated as End of Life and scheduled for obsolescence by the manufacturer. Procurement should account for limited availability and potential discontinuation. Verify current stock levels and lead times with authorized distributors before finalizing orders, as production may cease without further notice.
Selection Notes
Select this LIU for applications requiring integrated equalization and clock recovery in short haul T1/E1/J1 environments. Ensure compatibility with 1.8 V or 3.3 V logic levels and verify PCB layout requirements for the 640-BGA package. Consider alternative components if long-term supply stability is critical due to the End of Life status.
Part Context
The 82P2521BHG belongs to the 82P2521 series of telecom interface ICs designed for high-channel-count line interface applications. It complements other devices in the family by providing specialized short-haul capabilities with integrated signal processing features, targeting carrier-grade telecommunications equipment.
Replacement Considerations
No public confirmed substitute part numbers are available. Due to the End of Life status, direct replacements may require design modifications or selection of newer generation components from the manufacturer's portfolio.
