PSB 2132 H V2.2

Telecom Overview

The PSB 2132 is a two-channel codec filter for terminal applications, built around a central DSP core providing independent digital filters. It features an IOM-2 PCM interface compatible with 768 kbit/s buses and supports A-Law or µ-Law coding in selectable 8-bit time slots. The device includes programmable analog interfaces for electronic SLICs, seven signaling I/O pins per channel with debouncing, and two programmable tone generators. It operates on a single 5 V supply using advanced low-power mixed-signal CMOS technology within a P-MQFP-64 package.

Telecom Feature Summary

• DSP-based architecture with independent digital filters for AC impedance matching and transhybrid balancing
• IOM-2 compatible PCM interface supporting single and double clocking modes
• Programmable analog interface with high driving capability for direct transformer connection
• Integrated signaling interface with programmable debouncing and interrupt generation

Telecom Applications

• Small PBX systems
• Terminal Adapters
• Intelligent Network Terminals (NTs)

Telecom Procurement Notes

Verify component authenticity through authorized Infineon distributors or official channels. Confirm the specific version suffix matches project requirements. Review the Hardware Reference Manual for detailed electrical characteristics and timing diagrams before integration. Ensure proper handling of unused pins as specified in the pin definitions to maintain signal integrity.

Telecom Selection Notes

Select this component for designs requiring dual-channel voice processing with integrated filtering and signaling control. Verify that the system architecture supports the required IOM-2 bus speeds and single 5 V power supply. Consider the P-MQFP-64 package dimensions for board layout constraints. Evaluate the need for external SLICs based on the analog interface specifications.
