PEF21512EV1.2-G

Telecom Overview

The PEF21512EV1.2-G is a symmetric DSL frontend (SDFE) integrated circuit manufactured by Infineon Technologies under the SOCRATES series. Designed for telecommunications applications, this component supports SHDSL and ISDN interfaces with two internal circuits. It operates within a supply voltage range of 1.5V to 3.3V and consumes approximately 650 mW of power. The device is housed in a 324-LBGA package with a PG-LBGA-324-2 supplier variant, suitable for surface mount installation. It functions reliably across an extended industrial temperature range from -40°C to +85°C.

Telecom Feature Summary

• Integrated symmetric DSL frontend architecture optimized for line driver and receiver stages
• Supports multiple interface protocols including HDLC and serial communication standards
• Designed for low-power operation with efficient thermal management capabilities

Telecom Applications

• Symmetric Digital Subscriber Line (SDSL) modem implementations
• High-speed Digital Subscriber Line (HDSL) equipment
• Single-pair High-speed Digital Subscriber Line (SHDSL) network terminals

Telecom Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm lot codes and date codes against current inventory records. Ensure compliance with RoHS directives and REACH regulations as specified in official datasheets. Request detailed test reports for critical performance parameters before final acceptance.

Telecom Selection Notes

Evaluate compatibility with existing baseband processors regarding interface signaling levels and timing requirements. Assess thermal dissipation needs based on the 650 mW power consumption specification within the target enclosure design. Verify that the 324-LBGA footprint matches the printed circuit board layout constraints. Consider obsolescence risks associated with the discontinued product status when planning long-term production cycles.

Telecom Part Context

This component belongs to the Infineon SOCRATES family of telecom interface solutions. It serves as a specialized frontend processor for DSL technologies, bridging the physical layer signals with digital baseband processing units. The part represents a mature technology solution for single-pair high-speed data transmission over copper lines.

Telecom Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified sources. Due to the discontinued status, engineering teams must evaluate pin-compatible alternatives or redesign the interface circuitry to accommodate newer generation SDFE components from the manufacturer.
