CPC5621ATR

Telecom Overview

The CPC5621ATR is a LITELINK III single-package silicon phone line interface integrated circuit manufactured by IXYS Integrated Circuits Division. It functions as a Data Access Arrangement (DAA) for connecting low-voltage equipment to high-voltage telephone networks. The device supports 3.3 V or 5 V power supply operation and provides up to +10 dBm transmit power into a 600 Ω load. It features 3 kVrms line isolation and includes caller ID signal reception capabilities. Designed for speeds up to V.92, it complies with TIA/EIA/IS-968, UL1950, UL60950-1, EN/IEC 60950-1, CISPR22B, EN55024, and TBR-21 standards. The component operates within a temperature range of -40°C to 85°C and is housed in a 32-SOIC package.

Telecom Procurement Notes

Verify the current lifecycle status before procurement, as this component has been subject to discontinuation notifications. Confirm that the specific ATR suffix aligns with required reel packaging specifications. Ensure design compatibility with existing BOM constraints regarding the 32-SOIC footprint. Validate regulatory compliance requirements against the latest manufacturer documentation prior to finalizing orders.

Telecom Selection Notes

Select the CPC5621ATR when a compact, single-chip DAA solution is required for voice and data communication applications. This model is suitable for designs needing 3.3 V or 5 V operation with integrated caller ID reception. Consider this component for applications prioritizing reduced passive component count and simplified layout over discrete alternatives. Ensure the application environment falls within the specified operating temperature range.

Telecom Part Context

The CPC5621ATR belongs to the LITELINK III series of phone line interface ICs from IXYS Integrated Circuits Division. This series represents a family of silicon DAAs designed to replace complex discrete implementations. The CPC5621 variant specifically complements the CPC5620, offering similar integration benefits for telecommunications equipment manufacturers seeking standardized interfaces for global dial-up network compatibility.

Telecom Replacement Considerations

The CPC5620ATR is a closely related variant within the same LITELINK III family. Verify functional equivalence and pinout compatibility before substitution. Review specific datasheet differences regarding electrical characteristics and regulatory approvals to ensure the replacement meets all system requirements.
