Product details
Overview
PSB21150FV1.2D from Infineon Technologies is an ISDN S/T-interface PC adapter circuit (IPAC-X) supporting TE/LT-T/NT mode operation, featuring integrated HDLC controllers for D-channel processing, dual IOM-2 interface support, and on-chip transceiver synchronization logic. It delivers 192 kbit/s full-duplex data transfer, supports both serial and parallel microcontroller interfaces, and implements Layer-1 control per ITU-T I.430/I.431 standards for ISDN basic rate access in PC-based terminal equipment.
For engineers reviewing the PSB21150FV1.2D datasheet, PSB21150FV1.2D pinout, PSB21150FV1.2D application, or PSB21150FV1.2D equivalent, key selection considerations include its dual-mode S/T transceiver timing control, IOM-2 bus arbitration capability, C/I channel handling for command/indication signaling, and integrated D-channel HDLC framing with 128-byte FIFOs - all critical for ISDN terminal design compliance and interoperability.
Technical Context
The PSB21150FV1.2D implements a fully programmable ISDN Layer-1 controller with three operational modes: Terminal Equipment (TE), Line Termination – Transparent (LT-T), and Network Termination (NT). Its architecture integrates two independent HDLC controllers - one for D-channel processing and another for auxiliary S/Q-channel handling - each with dedicated 128-byte transmit/receive FIFOs and configurable frame formats.
It features a dual-interface microcontroller port (serial SCI + parallel 8-bit bus), programmable interrupt structure with maskable sources per functional block, and hardware-level transceiver synchronization via M-bit multiframe alignment. Clock generation includes a DPLL for jitter-tolerant receive clock recovery and a 768 kHz oscillator output (C768) for external line driver timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| D-Channel Data Rate | 16 kbit/s - Fixed-rate HDLC framing for ISDN D-channel signaling per I.430. |
| S/T Interface Mode Support | TE, LT-T, and NT modes - Enables use as terminal, line termination, or network termination device in basic rate ISDN systems. |
| IOM-2 Bus Width | 8-bit parallel - Supports direct connection to microcontrollers without glue logic for high-speed D-channel data exchange. |
| Receive FIFO Depth | 128 bytes per channel - Enables burst-mode D-channel frame buffering without host intervention during high-traffic periods. |
| Transmit FIFO Depth | 128 bytes per channel - Allows pre-loading of multiple ISDN frames (e.g., SETUP, CONNECT) before transmission initiation. |
| Oscillator Output | C768 at 768 kHz - Provides precise timing reference for external S/T line drivers and transformer coupling circuits. |
| Jitter Tolerance | ±100 ppm - Meets ITU-T G.823 requirements for DPLL-based clock recovery in noisy line environments. |
Pinout & Package
PSB21150FV1.2D is housed in a 128-pin LQFP package (20 × 20 mm, 0.4 mm pitch) with thermal pad, optimized for ISDN line interface PCB layout and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ACL | Activation Control Level | Open-drain output indicating active S/T link state; used for LED status or power management sequencing. |
| C768 | Oscillator Clock Output | 768 kHz square wave for synchronizing external line drivers and transformer bias networks. |
| SCI_CLK | Serial Control Interface Clock | Input clock for synchronous serial programming of internal registers (max 5 MHz). |
| IOM2_D0–D7 | IOM-2 Data Bus | 8-bit bidirectional parallel interface for high-throughput D-channel frame exchange with host MCU. |
| INT | Interrupt Request | Active-low open-drain signal asserting on HDLC frame completion, error detection, or transceiver event. |
| RESET | Hardware Reset Input | Asynchronous active-low reset clearing all internal state machines and register contents. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-mode S/T controller | Configurable as TE, LT-T, or NT per I.430/I.431 - eliminates need for separate mode-specific ICs in multi-role ISDN designs. |
| Dual HDLC engines | Independent D-channel and S/Q-channel controllers - enables simultaneous protocol stack handling (e.g., D-channel signaling + monitor channel diagnostics). |
| IOM-2 bus arbitration | Hardware priority logic for TIC/S-Bus D-channel access - prevents bus contention in multi-device ISDN backplanes. |
| Multiframe synchronization (M-bit) | Automatic alignment to 2048-bit S/T multiframe boundary - ensures deterministic timing for TE/LT-T mode transitions and layer-1 state machine coordination. |
| Integrated C/I channel handling | Dedicated registers (CIR0/CIX0, CIR1/CIX1) for command/indication message parsing - reduces host firmware overhead for ISDN call setup/teardown sequences. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ISDN S/T interface controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Siemens SLICOFI SLD21150 | Lacks integrated IOM-2 bus; requires external FIFO and address decoding logic. | Suitable only for custom ASIC-based designs with dedicated bus infrastructure. | Select when existing board layout already implements parallel FIFO interface and cost-per-board optimization outweighs integration benefit. |
| Infineon PSB21151FV1.2D | Includes enhanced ESD protection (±8 kV HBM) and extended temperature range (–40°C to +85°C). | Required for outdoor or uncontrolled environment deployments where ambient thermal cycling exceeds commercial grade limits. | Select when operating environment exceeds 70°C ambient or system-level ESD testing mandates >4 kV contact discharge margin. |
Compared with PSB21150FV1.2D, the SLD21150 increases design complexity and component count due to missing IOM-2 integration, while the PSB21151FV1.2D trades minor cost premium for guaranteed industrial reliability - making the original PSB21150FV1.2D optimal for cost-sensitive, temperature-controlled PC peripheral applications.

FAQ
Does PSB21150FV1.2D support both TE and NT modes simultaneously?
No. The PSB21150FV1.2D operates in only one S/T mode at a time - TE, LT-T, or NT - selected via configuration registers (TR_MODE and MODED) during initialization. Mode switching requires full reset and reconfiguration; concurrent operation is not supported by the hardware state machine architecture.
What is the maximum supported microcontroller interface speed for the parallel IOM-2 bus?
The parallel IOM-2 interface supports up to 10 MHz clock frequency, enabling sustained data transfer rates of 80 Mbit/s. Timing diagrams in Section 5.6 of the datasheet specify 45 ns minimum write pulse width and 35 ns setup/hold times relative to IOM2_CLK, requiring careful PCB trace length matching for reliable operation above 5 MHz.
Can the C768 oscillator output drive external line transformers directly?
No. C768 provides a 768 kHz logic-level square wave intended as a timing reference for external driver ICs (e.g., Infineon TLE6240), not for direct transformer coupling. Direct connection would violate voltage/current limits and compromise common-mode noise rejection; a dedicated line driver with current-limiting and differential output stage is mandatory.
Is there hardware support for D-channel CRC calculation in PSB21150FV1.2D?
Yes. The D-channel HDLC controller performs automatic FCS (Frame Check Sequence) generation and verification per ISO/IEC 3309 using the standard CRC-16 polynomial (x¹⁶ + x¹² + x⁵ + 1). CRC computation occurs transparently in hardware during frame transmission and reception, with error flags reported in STARD and ISTAD registers.
