Product details
Overview
PEB2447H-V12 from Siemens AG is a monolithic CMOS Memory Time Switch Extended Large (MTSXL) device for PCM telecommunication systems, functioning as a non-blocking 2048×2048 time/space switch with 32 input and 32 output PCM lines, 16.384 MHz device clock, TTL-compatible I/O, and IEEE 1149.1 boundary scan support - deployed in digital switching infrastructure for frame-aligned channel routing.
For engineers reviewing the PEB2447H-V12 datasheet, PEB2447H-V12 pinout, PEB2447H-V12 application, or PEB2447H-V12 equivalent, key selection criteria include PCM frame delay compensation capability, real-time input offset reprogramming without bit errors, tristate expansion support, built-in selftest via boundary scan, and Intel-type 8-bit demultiplexed µP interface compatibility.
Technical Context
The PEB2447H-V12 implements a fully non-blocking time-slot interconnection architecture for 4.096/8.192 Mbit/s PCM systems, using on-chip connection and data memory accessed via an 8-bit Intel-demultiplexed microprocessor interface. It supports dynamic frame alignment through programmable input offsets for 16 PCM inputs and individual line delay measurement on six dedicated FS inputs.
Its boundary-scan TAP controller complies fully with IEEE 1149.1, enabling test access to internal registers and built-in selftest (BIST) execution. The device guarantees glitch-free reconfiguration of input sampling points during operation - critical for maintaining bit integrity in live PCM traffic paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Capacity | 2048 × 2048 non-blocking PCM time slots - enables full-mesh channel routing in large-scale digital exchanges. |
| PCM Interface | 32 input + 32 output TTL-compatible serial PCM lines - directly interfaces standard E1/T1 framing hardware. |
| Device Clock | 16.384 MHz - precisely matches 2× E1 frame rate (2.048 MHz × 8), ensuring synchronous time-slot alignment. |
| Input Offset Control | Programmable per-channel offset for 16 inputs - compensates variable line propagation delays without service interruption. |
| Frame Measurement Inputs | 6 dedicated FS0–FS5 pins - measure frame wander across multiple PCM links for adaptive synchronization. |
| µP Interface | 8-bit Intel-demultiplexed bus (A0–A4, RD, WR, CS, D0–D7) - integrates with legacy 80Cxx/8051-based control planes. |
| Built-in Selftest | Fully accessible via boundary scan or µP command - validates internal memory, register access, and clock path integrity. |
Pinout & Package
PEB2447H-V12 is housed in a P-MQFP-100-2 (Plastic Metric Quad Flat Package, 100-pin, 0.5 mm pitch) with exposed thermal pad. Pin 1 marked by index notch; leads are lead-free and RoHS-compliant per Siemens 1997 manufacturing standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0–IN31 | PCM Serial Input | 32 TTL-level serial data inputs accepting 2.048 MHz or 4.096 MHz PCM streams - mapped to time-slot matrix rows. |
| OUT0–OUT31 | PCM Serial Output | 32 TTL-level serial outputs delivering switched time-slot data - driven with controlled slew rate for EMI reduction. |
| FS0–FS5 | Frame Sync Measurement | 6 dedicated frame-synchronization inputs used for real-time delay measurement and wander compensation. |
| CLK | Master Device Clock | 16.384 MHz input driving all internal timing - must be low-jitter to prevent bit misalignment in high-density switching. |
| SP | Synchronization Pulse | External system sync pulse aligning internal frame boundaries - enables multi-device phase coherence in tandem configurations. |
| A0–A4, CS, RD, WR, D0–D7 | µP Interface Bus | Intel-demultiplexed 8-bit address/data/control interface - allows direct register read/write without external glue logic. |
| TCK, TMS, TDI, TDO | JTAG Boundary Scan | IEEE 1149.1-compliant test access port - enables production testing, in-system diagnostics, and BIST activation. |
| VDD / VSS | Power Supply | Single 5 V ±5% supply with distributed decoupling pads - requires local 100 nF ceramic + 10 µF tantalum per power pair. |
Key Features
| Feature | Design Value |
|---|---|
| In-operation input offset reprogramming | Adjusts PCM frame sampling point dynamically without introducing bit errors - essential for maintaining BER <10⁻¹² in live networks. |
| Tristate output enable | Allows cascading multiple PEB2447H-V12 devices on shared PCM buses - supports tandem switching and capacity scaling. |
| Half-clock-step programmable clock shift | Enables fine-grained skew adjustment (±0.5 × 61.035 ns) on input/output clocks - corrects sub-bit-period timing mismatches. |
| 6-channel frame evaluation | Dedicated FS0–FS5 inputs measure frame arrival variance across diverse physical links - feeds adaptive delay compensation algorithm. |
| Direct register addressing | All 17 internal registers (MODR, CMDR, STAR, etc.) accessible via A0–A4 and CS/RD/WR - eliminates indirect addressing overhead. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar time-slot switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB2047H | Smaller 1024×1024 capacity; no FS0–FS5 frame measurement inputs; identical µP interface and clock architecture. | Limited to medium-scale exchanges or single-node PBX; lacks multi-link wander compensation. | Select when system scale ≤1024 channels and frame delay variation is negligible across links. |
| MT8985D1 | 2048×2048 switch but uses serial SPI µP interface; no built-in BIST; requires external frame sync logic. | Higher µP overhead for register access; unsuitable for safety-critical diagnostics without added test firmware. | Prefer only if board space constraints prohibit 100-pin MQFP and SPI integration is already standardized. |
Compared with PEB2447H-V12, PEB2047H reduces cost and power at the expense of scalability and adaptive synchronization, while MT8985D1 trades diagnostic robustness and parallel interface simplicity for package compactness - making PEB2447H-V12 optimal for carrier-class reliability and real-time frame integrity.

Manufacturer
Siemens AG Semiconductor Group (now Infineon Technologies) was a leading European semiconductor manufacturer specializing in industrial, telecom, and automotive ICs before its semiconductor division spun off in 1999.
The MTSXL product line - including PEB2447H-V12 - was engineered specifically for carrier-grade digital telephony infrastructure, emphasizing deterministic timing, fault-tolerant configuration, and seamless integration into legacy µP-controlled switching systems.
FAQ
What is the maximum supported PCM data rate per input/output line?
The PEB2447H-V12 supports two standard rates: 2.048 Mbit/s (E1) and 4.096 Mbit/s (double-E1). Each INx/OUTx line operates at one of these fixed rates - selected via external configuration and verified by the 16.384 MHz master clock (exactly 8× 2.048 MHz). No oversampling or rate adaptation is performed internally.
Does PEB2447H-V12 support hot insertion or live reconfiguration?
Yes - input offset registers can be rewritten during active PCM traffic without causing bit errors or frame loss. This is guaranteed by internal handshake logic that stalls switching matrix updates until frame boundaries, preserving bit integrity. Full device reset (via RES pin) still requires service interruption.
How is frame synchronization maintained across multiple PEB2447H-V12 devices?
Multiple units synchronize via the SP (Synchronization Pulse) input and shared CLK signal. When cascaded, one device acts as master SP source while others use SP as input; FS0–FS5 measurements feed a centralized delay compensation algorithm running on the host µP - not on-chip.
Is the PEB2447H-V12 compliant with modern RoHS or REACH requirements?
Originally manufactured in 1997 under Siemens' pre-RoHS process, the PEB2447H-V12 contains leaded solder in its P-MQFP-100-2 package. Aetrix Electronics supplies only tested, traceable legacy stock meeting original Siemens specifications - not RoHS-compliant re-manufactured versions.
