PXF 4222 E V1.3-G

Overview

The PXF4222EV1.3-G is an ATM interworking controller from Infineon’s IWORX-P family, designed for transporting ATM traffic over PDH networks. It integrates IMA, a microcontroller, and RAM on a single chip. The device supports AAL1 mode with up to 256 connections and handles voice/video adaptation at speeds up to 16 Mbit/s. Key electrical parameters include a 3.3 V I/O supply, a 1.8 V core voltage, and power consumption under 2 W. It operates within a temperature range of -40°C to +85°C and is housed in a P-BGA-388 package.

Feature Summary

• Integrates IMA, Microcontroller, and RAM for system-on-chip functionality
• Supports AAL1 mode with Channelized/unchannelized CES and CAS
• Provides 8 E1/T1/J1 interfaces with direct connection to external framers
• Includes Utopia interface (Level 1 and 2) and 16/32-bit Microprocessor Interface

Applications

• 3G base transceiver stations (Node B) and radio network controllers (RNC)
• Multiservice linecards
• WAN routers
• DSLAM/DLC uplink cards

Procurement Notes

Verify the specific revision suffix 'V1.3' against official documentation to ensure compatibility with existing designs. Confirm RoHS compliance status through current manufacturer declarations. Check availability as this component may be subject to discontinuation or limited stock constraints.

Selection Notes

Select this controller for applications requiring ATM-to-PDH interworking with integrated memory and processing. Ensure the design accommodates the 3.3 V I/O and 1.8 V core voltage requirements. Verify that the host system can support the Message Based Interface for configuration and operation.

Part Context

The PXF4222 belongs to the IWORX-P family, which extends the capabilities of the established IWE-8 by adding IMA, a microcontroller, and RAM. This integration optimizes space and power economy while supporting easy network migration paths between 2G and 3G mobile networks via AAL1 and CES.

Replacement Considerations

No public substitute part numbers are documented. Consider evaluating other members of the IWORX family if functional equivalence is required.
