Procurement Notes

Verify RoHS compliance status prior to procurement, as documentation indicates potential non-compliance for this specific variant. Confirm the active lifecycle status with the manufacturer or authorized distributors to ensure long-term availability. Validate that the package type matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when designing systems requiring dedicated hardware for eight-channel E1/T1 interworking. Ensure the application environment supports the specific voltage levels and signal integrity requirements defined in the official datasheet. Compare against similar models like the PXB4221EV3.3 if different interface counts are required.

Part Context

This part belongs to Infineon's family of interface ICs focused on telecommunications modems and interworking elements. These components are critical for bridging digital transmission standards in modern communication networks, providing reliable signal handling for E1 and T1 protocols.

Replacement Considerations

The PXB4221EV3.3 is a documented comparable part from the same manufacturer offering similar interworking capabilities. Verify pin compatibility and functional equivalence through official datasheets before substitution.
