PEB2447H-V12

Specialized Overview

The Infineon PEB2447H-V12 is a monolithic CMOS Memory Time Switch Extended Large (MTSXL) device designed for non-blocking time/space switching in 4.096- or 8.192-Mbit/s PCM systems. Operating with a 16.384 MHz device clock, it connects up to 2048 incoming PCM channels to 2048 outgoing PCM channels. The component features 32 input and 32 output PCM lines, an 8-bit Intel-type demultiplexed microprocessor interface, and fully IEEE 1149.1 compatible boundary scan support. It utilizes a single 5 V power supply and includes built-in self-test mechanisms.

Specialized Feature Summary

• Non-blocking switching capability for high-capacity PCM channel interconnection
• Integrated frame measurement inputs for individual line delay compensation
• Programmable clock shift with half-clock step resolution for input and output alignment
• Built-in self-test mechanism accessible via microprocessor or boundary scan interface

Specialized Applications

• Time/space switching in 4.096-Mbit/s PCM communication systems
• Time/space switching in 8.192-Mbit/s PCM communication systems
• Tandem operation and expansion of existing switching matrices

Specialized Procurement Notes

Verify the specific ordering code Q67103-H6594 against current Siemens/Infineon semiconductor catalogs. Confirm package compatibility with P-MQFP-100-2 footprints. Ensure design compliance with critical component usage restrictions for life-support systems as defined in the original datasheet.

Specialized Selection Notes

Select this component for applications requiring large-scale PCM channel switching within a single chip. Consider the 16.384 MHz clock requirement and TTL-compatible I/O levels. Evaluate the need for frame wander compensation capabilities provided by the six additional FS inputs and programmable input offsets.

Specialized Part Context

The PEB 2447 H represents Version 1.2 of the MTSXL family, serving as a capacity expansion of the earlier MTSL (PEB 2047). Originally published by Siemens AG Semiconductor Group in March 1997, it remains a specialized solution for telecommunication switching infrastructure before being superseded by newer integrated technologies.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Infineon/Siemens archives for modern equivalents or verify pin-to-pin compatibility with updated switching ICs.
