Telecom Procurement Notes

Verify the specific ordering suffix against the datasheet revision history to confirm the package type. The 'E' variant typically corresponds to the LBGA package, while other suffixes may indicate different form factors. Confirm RoHS compliance status through official Infineon documentation before procurement.

Telecom Selection Notes

Select this component when designing systems requiring quad-channel E1, T1, or J1 line interfacing. Ensure the host processor supports the required asynchronous or serial communication protocols. Verify that the system power architecture accommodates the specified 1.8V and 3.3V supply rails.

Telecom Part Context

This part belongs to the QuadFALC family of telecom interface ICs from Infineon Technologies. It serves as a line interface unit for digital carrier networks. The V2.1 designation indicates a specific hardware revision with updated pinouts and features compared to earlier versions.

Telecom Replacement Considerations

Check for direct substitutes within the same QuadFALC family. Verify compatibility regarding package dimensions and pin assignments if replacing with variants like the HT version.
