PXB4221EV3.4

Overview

The PXB4221EV3.4 is an ATM UNI (Asynchronous Transfer Mode User Network Interface) modem integrated circuit manufactured by Infineon Technologies. It supports a single channel with a data rate of 2.048 Mbps and operates at a supply voltage of 3.3V. The component features a 25-pin configuration for interface connectivity.

Feature Summary

Supports Asynchronous Transfer Mode User Network Interface (ATM UNI) protocols
Designed for single-channel operation at 2.048 Mbps data rates
Operates on a 3.3V power supply

Applications

ATM network interface implementations
Telecommunications equipment requiring UNI compliance
Digital signal processing systems operating at E1 speeds

Procurement Notes

Verify RoHS compliance status prior to procurement, as some sources indicate non-compliance. Confirm package type and pin count against specific design requirements. Ensure the 3.3V supply voltage aligns with system power rails. Validate that the 2.048 Mbps single-channel specification meets application bandwidth needs.

Selection Notes

Select this component for applications requiring dedicated ATM UNI modem functionality. Consider the 3.3V operating voltage when designing power management circuits. Evaluate the 25-pin package constraints for PCB layout. Ensure compatibility with existing digital interfaces supporting 2.048 Mbps transmission rates.

Part Context

This part belongs to Infineon's portfolio of interface modems and ICs. It serves specialized telecommunications roles rather than general-purpose communication. The device integrates modem functions into a single chip solution for ATM networks.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify functional equivalence with other ATM UNI modems if replacement is necessary.
