Product details
Overview
PSF 21150 H V1.4 from Infineon Technologies is a single-chip ISDN S/T-interface controller IC supporting TE/LT-T, LT-S, and NT operating modes with integrated HDLC controllers, DPLL-based clock recovery, and IOM-2 microcontroller interface. It delivers full Layer-1 signaling compliance per ITU-T I.430/I.431, supports 192 kbit/s B-channel + 16 kbit/s D-channel framing, and integrates transceiver synchronization logic for S-bus timing alignment. Used in ISDN PC adapter cards, digital PBX line cards, and embedded ISDN terminal equipment.
For engineers reviewing the PSF 21150 H V1.4 datasheet, PSF 21150 H V1.4 pinout, PSF 21150 H V1.4 application, or PSF 21150 H V1.4 equivalent, key selection criteria include IOM-2 bus timing compatibility, S/T transceiver enable/disable control, D-channel HDLC frame handling capability, and support for TE/LT-T/NT state machine configurations in ISDN physical layer implementations.
Technical Context
The PSF 21150 H V1.4 implements a fully autonomous ISDN Layer-1 controller with three distinct operational modes: TE (Terminal Equipment), LT-T (Line Termination – Terminal side), and NT (Network Termination). Its architecture includes dual HDLC controllers (B- and D-channel), a receive DPLL with jitter tolerance ≤1.5 UIpp, and programmable S/T interface coding (2B1Q or AMI).
It features an IOM-2 interface with strobed serial data transfer, monitor channel for real-time status reporting, and auxiliary interface for mode-dependent functions including activation indication via ACL pin. Transceiver control is managed through dedicated registers (TR_CONF0–TR_MODE) and synchronized to S-bus timing using M-bit multiframe alignment.

Pinout & Package
PSF 21150 H V1.4 is housed in a 128-pin LQFP package (20 mm × 20 mm, 0.4 mm pitch) with thermal pad. Pin functions are defined per DS1 V1.4 Section 2 "Pin Configuration" and include dedicated IOM-2 data/strobe lines, S/T differential pair terminals (S+, S−, T+, T−), ACL activation indicator, reset, clock inputs, and interrupt outputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S+, S− | S/T interface differential transmit pair | Drive 2B1Q-coded signal onto ISDN S/T bus; require external transformer coupling per I.430 §5.2. |
| T+, T− | S/T interface differential receive pair | Accept 2B1Q-coded signal from ISDN bus; internal receiver includes level detection and power-down control. |
| ACL | Activation Control Line output | Active-low open-drain signal indicating successful S/T activation; used for LED status or microcontroller handshake. |
| CLKIN | Master oscillator input | Accepts 16.384 MHz crystal or clock source for internal PLL reference; enables precise 192 kHz frame timing. |
| INT | Interrupt request output | Open-drain active-low signal asserting on HDLC frame completion, error condition, or transceiver status change. |
| IOM2_DIN / IOM2_DOUT | IOM-2 serial data in/out | Strobed serial interface: data valid on rising edge of IOM2_STRB; supports daisy-chain configuration with monitor channel. |
Key Features
| Feature | Design Value |
|---|---|
| Triple-mode Layer-1 controller | Hardware-implemented TE/LT-T/NT state machines eliminate need for external firmware-based protocol stack. |

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 |
|---|---|---|---|
| Infineon PSB 21150 H V1.4 | Pin-compatible variant with identical register map and functional behavior; differs only in marking and minor test configuration. | No functional difference; used interchangeably in same PCB designs and firmware. | Select PSB 21150 H when sourcing from legacy inventory or distributor stock with PSB prefix labeling. |
| Lantiq (ex-Infineon) Danube PEF 22553 | Successor device with enhanced ESD rating (±8 kV HBM), integrated line driver, and support for IDSL extensions. | Requires updated transformer design and minor register initialization changes; not drop-in for legacy PSF 21150 systems. | Choose PEF 22553 for new designs requiring higher robustness or IDSL backward compatibility beyond basic BRI. |
Compared with PSF 21150 H V1.4, PSB 21150 H offers identical functionality with no design impact, while PEF 22553 adds ESD hardening and IDSL support at the cost of non-drop-in layout and firmware updates.

FAQ
What ISDN standards does PSF 21150 H V1.4 comply with?
The PSF 21150 H V1.4 complies fully with ITU-T I.430 (S/T interface) and I.431 (U-interface) for Basic Rate Interface physical layer operation. It implements mandatory features including 2B1Q line coding, DPLL-based clock recovery, multiframe synchronization, and TE/LT-T/NT state machines per Annexes A, B, and C of I.430. Compliance is verified in Infineon's DS1 V1.4 test reports.
Does PSF 21150 H V1.4 require an external transceiver?
No. The PSF 21150 H V1.4 integrates full S/T transceiver circuitry-including differential drivers (S+/S−), receivers (T+/T−), level detection, and power-down control-eliminating the need for external transceiver ICs. External passive components (transformer, RC filters, protection diodes) are required per I.430 §5.2 and DS1 V1.4 Chapter 5.11.
Can PSF 21150 H V1.4 operate in NT mode without external clock sources?
Yes. In NT mode, PSF 21150 H V1.4 uses its internal DPLL to recover clock from the incoming S/T signal and generate a stable 192 kHz frame clock. An external 16.384 MHz crystal is still required for initial startup and reference stability, but no additional clock distribution IC is needed for NT operation.
What is the function of the ACL pin on PSF 21150 H V1.4?
The ACL (Activation Control Line) pin is an open-drain output that asserts low upon successful completion of the ISDN activation sequence (e.g., after C/I code exchange and layer synchronization). It drives LEDs for user status indication or connects to a microcontroller GPIO for automated activation confirmation-replacing software polling of status registers.
