PEF32002VTV12

Telecom Overview

The PEF32002VTV12 is a dual-channel codec and Subscriber Line Interface Circuit (SLIC) manufactured by MaxLinear. It integrates CMOS-based voice codecs with high-voltage SLIC functionality within a single package to provide a compact line interface solution. The device supports balanced ringing up to 85 Vrms and unbalanced ringing up to 50 Vrms, accommodating Caller ID Type 1 and Type 2 transmission standards. It features integrated DC/DC PWM control, DTMF generation and reception, and loop start signaling. The component includes comprehensive test and diagnostic capabilities such as GR-909 sequences and AC level meters for voice quality assessment.

• Supports global programmability for AC transmission parameters compliant with ITU-T Q.552 and Telcordia GR-57-Core standards
• Includes integrated DC/DC PWM controller and extensive diagnostic functions

Telecom Applications

• Analog terminal adapters
• Wired EMTA and set-top boxes
• DSL Integrated Access Devices (IAD)
• PBX and business gateways
• VoIP terminals

Telecom Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package type and temperature rating. Confirm RoHS compliance status through the supplier's declaration of conformity. Request the latest revision data sheet to validate pinout compatibility and electrical characteristics before finalizing procurement orders.

Telecom Selection Notes

Select this component for designs requiring high integration of voice processing and line interface functions in a reduced footprint. Ensure the application environment supports the required voltage levels for balanced and unbalanced ringing. Verify that the host system can accommodate the SPI or CSI interface protocols used for configuration and data transfer.

Telecom Part Context

This part belongs to the PEF3 series of telecom interface ICs from MaxLinear. It serves as a specialized solution for customer premises equipment (CPE) applications where cost optimization and design flexibility are critical. The integration of codec and SLIC functions distinguishes it from discrete component solutions.

Telecom Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence with other models in the family without verifying pinout and parameter alignment.
