CPC5622ATR

Telecom Overview

The CPC5622ATR is a LITELINK III single-package silicon phone line interface integrated circuit manufactured by IXYS Integrated Circuits. It functions as a Data Access Arrangement (DAA) for connecting low-voltage equipment to high-voltage telephone networks in voice and data communication applications. The device supports V.92 modem speeds and operates on 3.3V or 5V power supplies. It provides 3 kVRMS line isolation and includes simultaneous ringing detection and Caller ID monitoring capabilities. The component is housed in an SOIC-32 package and is designed for worldwide dial-up network compatibility.

Telecom Feature Summary

• Integrated DAA solution supporting V.92 modem speeds with superior voice quality and gain accuracy
• Simultaneous full-wave and half-wave ringing detection with Caller ID monitoring for global applications
• High voltage isolation of 3 kVRMS between line side and system side circuits

Telecom Applications

• Computer telephony integration and VoIP gateways
• PBX systems and satellite or cable set-top boxes
• Standard modems, fax machines, and voicemail systems
• Embedded modems for POS terminals, automated banking, and remote metering

Telecom Procurement Notes

Verify the manufacturer designation carefully, as Clare was acquired by IXYS. Confirm the specific suffix 'ATR' corresponds to the required reel packaging format. Ensure compliance with regional telecommunications standards such as TIA/EIA/IS-968 or EN/TBR-21 is validated against the latest datasheet revisions before procurement.

Telecom Selection Notes

Select this component when a complete silicon DAA solution is required to minimize passive component count and PCB space. It is suitable for designs needing 3.3V or 5V operation with integrated ringing detection. Compare against discrete solutions if board space is not constrained, noting that this IC consolidates multiple functions into a single package.

Telecom Part Context

This part belongs to the LITELINK III series of phone line interface ICs originally developed by Clare, Inc., now part of IXYS Integrated Circuits. The series is designed to replace complex discrete DAA circuits. The CPC5622 variant specifically targets applications requiring robust isolation and comprehensive signaling features for international telephone network connectivity.

Telecom Replacement Considerations

Direct replacements may include other LITELINK III variants from the same family, such as the CPC5620, depending on specific feature requirements like transmit power or isolation levels. Verify pinout compatibility and electrical specifications against the target application before substitution.
