PEB 2466 H V2.2

Telecom Overview

The PEB 2466 H V2.2 is a four-channel codec filter with PCM and microcontroller interface, part of the SICOFI®4-µC family. It integrates a central DSP core providing independent digital filters for each channel, connecting to external subscriber line interface circuits (SLICs) via analog I/O pins. The device supports A-Law or µ-Law coding within selectable 8-bit time slots on two PCM highways. It features a serial microcontroller interface for programming modes and filter characteristics, including AC impedance matching and transhybrid balancing. Available in standard (PEB) and extended temperature (PEF) versions, it operates on a single 5 V supply.

Telecom Feature Summary

• Integrates a central DSP core with independent digital filter structures for all four channels.
• Supports direct driving of transformers through high analog driving capability.
• Features programmable digital filters for AC impedance matching, transhybrid balancing, and frequency response adaptation.
• Includes seven SLIC-signaling I/O pins per channel with programmable debouncing functions.

Telecom Applications

• Analog linecards for Central Offices and PBXs
• Digital Loop Carrier (DLC) Systems
• Fiber-to-the-Curb (FTTC) Systems

Telecom Procurement Notes

Verify the specific ordering suffix against Infineon's official documentation to confirm temperature range and package variant. Ensure compatibility with the required signaling interface and PCM data rates. Confirm that the design adheres to the specified absolute maximum ratings and operating voltage constraints defined in the hardware reference manual.

Telecom Selection Notes

Select the PEB 2466 for standard temperature applications (0 °C to +70 °C) and the PEF 2466 for extended ranges (-40 °C to +85 °C). Ensure the system architecture supports the required serial microcontroller interface timing and PCM highway synchronization. Verify that the analog interface components match the specified coupling capacitor requirements for optimal signal integrity.

Telecom Part Context

The PEB 2466 belongs to the SICOFI®4-µC family of four-channel codec filters. It shares architectural similarities with other members like the PSB 2132 and PEB 2266 but offers specific DSP-based filtering capabilities. The version 2.2 revision indicates updates to the hardware reference manual, ensuring alignment with current manufacturing specifications and errata sheets published by Infineon Technologies.
