Infineon Technologies PEB2075N-V13TR

Overview

PEB2075N-V13TR from Siemens AG is an ISDN D-Channel Exchange Controller (IDEC®) IC implementing four independent HDLC channels with 64-byte FIFO per channel/direction, CRC checking/generation, flag detection, zero insertion/deletion, and programmable time slots up to 4 Mbit/s. It supports IOM® or PCM interfaces and operates in single/quad connection modes for telecommunication switching applications.

For engineers reviewing the PEB2075N-V13TR datasheet, PEB2075N-V13TR pinout, PEB2075N-V13TR application, or PEB2075N-V13TR equivalent, key selection criteria include HDLC channel count, FIFO depth per direction, µP interface mode (multiplexed/demultiplexed), interrupt structure (vectored), and support for contention resolution in packet-switched ISDN line cards.

Technical Context

The PEB2075N-V13TR implements a dedicated serial communication architecture for ISDN D-channel signaling, integrating four autonomous HDLC protocol engines with full frame handling-including address recognition, abort detection, and C/I channel management. Its dual-mode µP interface supports both Siemens/Intel (ALE-controlled multiplexing) and Motorola (R/W, DS) bus protocols.

It features time-slot control (TSC) output for external PCM driver synchronization, collision data receive (CDR) input for contention resolution, and programmable data rates across all channels. The device operates within a 5 V ±10% supply range and consumes less than 50 mW during active operation.

Manufacturer

Siemens AG was a German industrial conglomerate whose Semiconductor Group developed foundational telecom ICs including the IDEC® family, later spun off into Infineon Technologies in 1999.

The PEB2075 belongs to the IDEC® (ISDN D-Channel Exchange Controller) product line, designed specifically for hardware-accelerated HDLC protocol handling in centralized and distributed ISDN switching architectures.

FAQ

What µP interface modes does the PEB2075N-V13TR support?

The PEB2075N-V13TR supports both Siemens/Intel-style (multiplexed AD0–AD7 with ALE) and Motorola-style (separate R/W and DS signals) microprocessor interfaces. Configuration is determined by external strap pins and internal register settings; the P-LCC-44 package provides full pin access for either mode, including A0–A6 for demultiplexed addressing.

Does the PEB2075N-V13TR integrate clock generation or require external timing?

The PEB2075N-V13TR requires external clock inputs: DCL (data clock) and FSC (frame sync) must be supplied from a system clock generator or PCM interface. It does not contain an internal oscillator or PLL; timing is fully synchronous to these externally driven signals, ensuring deterministic latency in time-critical ISDN signaling.

How is collision resolution implemented in the PEB2075N-V13TR?

Collision resolution is handled via the CDR (collision data receive) input and internal contention logic that monitors simultaneous transmit requests across HDLC channels. When conflict is detected, the device prioritizes based on programmable channel priority registers and asserts status flags-enabling firmware to arbitrate or retransmit without hardware redesign.

Is the PEB2075N-V13TR RoHS compliant?

The original Siemens PEB2075N-V13TR (1992 design, P-LCC-44) predates RoHS legislation and contains leaded solder in its ceramic package. Infineon's later rebranded versions may offer RoHS-compliant variants; confirmation requires checking current Infineon datasheet revision and ordering code suffixes such as "-F" or "-G" indicating lead-free finish.
