PEB22504HT-V11

Specialized Overview

The PEB 22504 is a QuadLIU™ Quad Line Interface Unit designed for E1, T1, and J1 applications. It integrates four complete channels on a single chip to reduce board space and power consumption. The device supports long-haul and short-haul analog or digital line connections with selectable line codes including HDB3, B8ZS, and AMI. It features crystal-less jitter attenuation using an integrated digital phase-locked loop and a flexible master clock unit operating between 1.02 MHz and 20 MHz. The component utilizes a P-TQFP-100-3 package and operates on a single 3.3 V supply within a temperature range of -40°C to +85°C.

Specialized Feature Summary

• Integrates four independent receive and transmit circuits for simultaneous multi-channel operation
• Supports programmable pulse shaping and line build-out for CSU signals
• Includes built-in diagnostic capabilities such as PRBS generation and local/remote loopback
• Features a flexible microprocessor interface compatible with Intel and Motorola bus standards

Specialized Applications

• Wireless Basestations
• ATM and Frame Relay Gateways
• CSUs and DSUs
• Internet Access Equipment
• Digital Access Cross-connect Systems (DACS)

Specialized Procurement Notes

Verify the specific version suffix against official documentation, as revisions may alter electrical characteristics or pin compatibility. Confirm that the required operating voltage aligns with the 3.3 V specification. Ensure the design accommodates the P-TQFP-100-3 package dimensions and thermal requirements for the intended application environment.

Specialized Selection Notes

Select this component when a high-density solution for multiple E1/T1/J1 interfaces is required. It is suitable for designs needing integrated jitter attenuation without external crystals. Consider the available register configuration options for customizing line coding and alarm monitoring functions to meet specific network standards.

Specialized Part Context

This device belongs to Infineon's QuadLIU family of telecommunication interface ICs. It serves as a bridge between digital framing ASICs and physical transmission lines. The architecture consolidates functions typically distributed across multiple discrete components into a single CMOS integrated circuit.

Specialized Replacement Considerations

Check for updated versions within the same product family. Verify pin-to-pin compatibility if substituting with other quad-line interface units from different manufacturers.
