Product details
Overview
PEB2086H-V14TR from Siemens AG is an ISDN Subscriber Access Controller (ISAC®-S) IC designed for Layer-1 and Layer-2 protocol handling in Basic Rate Interface (BRI) terminal equipment (TE) and network termination (NT) applications. It supports IOM®-1 and IOM®-2 microprocessor interfaces, provides full S/T interface analog/digital layer functions, integrates HDLC framing with 128-byte FIFOs, and operates at 5 V supply with industrial temperature range (–40 °C to +85 °C).
For engineers reviewing the PEB2086H-V14TR datasheet, PEB2086H-V14TR pinout, PEB2086H-V14TR application, or PEB2086H-V14TR equivalent, key selection considerations include S/T interface compliance (ETSI/ITU-T I.430), dual-mode IOM® interface timing, integrated MONITOR/C/I channel support, and TE/NT mode configurability via register-controlled state machines.
Technical Context
The PEB2086H-V14TR implements a complete ISDN BRI physical layer (Layer-1) transceiver with adaptive receiver characteristics, timing recovery, and level-detection power-down in TE mode. It includes analog front-end circuitry for S/T interface compliance, including receive signal oversampling and external protection interface support.
At Layer-2, it executes HDLC frame processing with automatic CRC generation/checking, bit-stuffing/unstuffing, and frame synchronization. Its register-mapped architecture supports both auto-mode protocol operation and direct microprocessor control of B-, D-, S-, and Q-channels via dedicated command/indication registers and interrupt-driven status reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 5 V ± 5 % - ensures compatibility with standard TTL/CMOS microprocessor buses and stable analog biasing for S/T interface circuitry. |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial and telecom terminal equipment deployed in uncontrolled environments. |
| S/T Interface Compliance | ITU-T I.430 / ETSI TS 101 549 - guarantees interoperability with public ISDN networks and certified NT devices. |
| FIFO Depth | 128 bytes per channel (RX/TX) - enables burst-mode data transfer without microprocessor overhead during high-traffic D-channel signaling. |
| IOM® Interface Modes | IOM®-1 (8-bit, 2-MHz max) and IOM®-2 (16-bit, 4-MHz max) - supports flexible host processor integration from 8-bit controllers to 16-bit embedded CPUs. |
| Interrupt Sources | 12 maskable interrupt types (e.g., RX FIFO full, TX FIFO empty, D-channel frame received) - enables deterministic real-time response to ISDN layer events. |
| TE/NT Mode Support | Configurable via MODE register and external pins - allows single-hardware design to serve as either terminal equipment or network termination unit. |
Pinout & Package
PEB2086H-V14TR is housed in a 64-pin plastic leaded chip carrier (PLCC-64) package with J-leads, optimized for surface-mount assembly and thermal reliability in telecom line cards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Master Clock Input | Accepts 16.384 MHz crystal or external clock; drives internal PLL for S/T interface timing and HDLC bit-rate derivation. |
| RESET | Active-Low Asynchronous Reset | Forces all registers to default state and halts S/T interface activity; required before initialization sequence. |
| INT | Open-Drain Interrupt Output | Asserts low on pending interrupt condition; compatible with shared interrupt bus in multi-peripheral systems. |
| RD/WR | Read/Write Control | Separate active-low signals for IOM®-1 mode; enables non-multiplexed 8-bit parallel access to internal registers. |
| A0–A7 | Address Bus (IOM®-1) | Directly maps to internal register address space (00h–3Fh); no address latching required. |
| D0–D7 | Data Bus (IOM®-1) | Bidirectional 8-bit path for register read/write; supports byte-aligned HDLC frame payload transfers. |
| STX | S/T Transmit Output | Differential current-mode output driving transformer-coupled S/T line; meets I.430 voltage swing and rise/fall time specs. |
| SRX | S/T Receive Input | Differential input with adaptive threshold and oversampling; recovers data under line impairments up to 6 dB SNR. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated S/T Analog Front-End | Eliminates need for external line interface circuitry (LIC), reducing BOM count and PCB area in ISDN TE designs. |
| IOM®-2 16-bit Host Interface | Enables faster register access and higher throughput for D-channel signaling stacks running on 16-bit MCUs. |
| Auto-Mode Protocol Engine | Offloads Layer-2 HDLC framing, CRC, and state management from host CPU-reducing firmware complexity and latency. |
| MONITOR and C/I Channel Support | Provides dedicated hardware paths for monitoring S/T line status and exchanging layer-1 commands/indications without CPU intervention. |
| TE/NT Mode Flexibility | Single silicon part serves both endpoint and network-side roles via software configuration-simplifying inventory and design reuse. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ISDN subscriber access controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Siemens PEB2085H-V14TR | Single IOM®-1 interface only; no IOM®-2 support; lacks S-frame/multiframe sync (Section 2.5.9); no TIC bus access. | Targeted at cost-sensitive TE-only designs without NT capability or advanced timing features. | Select when IOM®-2 bandwidth and NT-mode flexibility are unnecessary and BOM cost is critical. |
| Infineon ISAC-S (PMB 2086) | Pin-compatible successor with extended EEPROM interface, enhanced ESD protection (±8 kV HBM), and updated qualification per AEC-Q100 Grade 2. | Preferred for new designs requiring automotive-grade reliability or long-term supply continuity post-Siemens semiconductor divestiture. | Choose for new industrial or automotive ISDN modules where lifecycle assurance and robustness exceed legacy PEB2086H-V14TR specifications. |
Compared with PEB2085H-V14TR, PEB2086H-V14TR adds NT-mode support and multiframe sync-enabling dual-role deployment; versus PMB2086, it lacks EEPROM integration and automotive qualification but remains viable for legacy telecom infrastructure upgrades with existing toolchains.

FAQ
What is the maximum clock frequency supported for the IOM®-2 interface?
The PEB2086H-V14TR supports up to 4 MHz for the IOM®-2 interface in 16-bit mode, enabling efficient register access and HDLC frame transfers with minimal wait states when paired with compatible microprocessors such as the Intel 80C186 or Motorola 68302.
Does PEB2086H-V14TR require external analog line interface components?
No-PEB2086H-V14TR integrates the complete S/T analog front-end, including transmit driver, receive amplifier, adaptive threshold detector, and protection interface pins. Only a center-tapped transformer and basic RC filter network are needed for full I.430 compliance.
How is TE vs. NT mode configured?
TE/NT mode is selected via the MODE register (bit 7) and confirmed by the state of the MODE pin during reset. Software writes to STAR2 register (bit 0) finalize the operational role, enabling dynamic reconfiguration without hardware change.
Can PEB2086H-V14TR handle simultaneous B-channel data and voice traffic?
Yes-the IC supports time-division multiplexing of two independent 64 kbps B-channels, allowing concurrent voice (PCM-encoded) and data (X.25 or transparent) streams. The HDLC engine manages D-channel signaling independently, ensuring no contention between control and payload paths.
