Product details
Overview
PSB 21150 F 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 ISDN protocol handling, 2×64 kbit/s B-channel + 16 kbit/s D-channel support, and on-chip transceiver synchronization logic for S/T-line interfacing in PC adapter and terminal equipment.
For engineers reviewing the PSB 21150 F V1.4 datasheet, PSB 21150 F V1.4 pinout, PSB 21150 F V1.4 application, or PSB 21150 F V1.4 equivalent, this device serves as a wired communications IPAC-X platform component requiring precise S/T timing alignment, IOM-2 bus timing compliance, and C/I channel command/indication handling in ISDN endpoint designs.
Technical Context
The PSB 21150 implements a dual-HDLC architecture-one for D-channel (16 kbit/s) and one for monitor channel-with independent FIFOs, status registers, and interrupt control. Its receive PLL (DPLL) locks to incoming S/T line clock with ±100 ppm tolerance and supports jitter filtering per ITU-T G.823.
Layer-1 state machines are fully programmable per mode (TE, LT-T, LT-S, NT), with dedicated C/I code handling, activation/deactivation sequencing, and S/T delay compensation for TE/LT-T mode. The IOM-2 interface operates at up to 8 MHz with strobed data clock and serial data strobe signal support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| S/T Interface Mode Support | TE, LT-T, LT-S, and NT modes-enables full interoperability across ISDN terminal, line termination, and network termination roles. |
| D-Channel Data Rate | 16 kbit/s HDLC-meets ITU-T I.430 physical layer specification for D-channel framing and error detection. |
| B-Channel Capacity | 2 × 64 kbit/s-supports simultaneous voice/data bearer channels in basic rate interface (BRI) applications. |
| Receive PLL Jitter Tolerance | ±100 ppm input frequency deviation-ensures robust clock recovery under line impairments per G.823 Class 3. |
| IOM-2 Bus Clock Max | 8 MHz-defines maximum microcontroller interface throughput for register access and frame buffer management. |
| Transceiver Sync Logic | Integrated S-transceiver synchronization-eliminates need for external sync circuitry in S/T interface design. |
| Monitor Channel Support | Dedicated HDLC controller with handshake and timeout-enables reliable diagnostics and maintenance communication over S/T line. |
Pinout & Package
PSB 21150 F V1.4 is housed in a 128-pin LQFP package (20 mm × 20 mm, 0.4 mm pitch) with thermal pad. Pin functions are validated per Infineon DS1 V1.4 (2003-01-30), Section 2 "Pin Configuration".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ACL | Activation Control Level | Open-drain output indicating active S/T connection state-used for hardware handshaking with external logic or LEDs. |
| CLKI | External Clock Input | Accepts 16.384 MHz crystal or oscillator reference for internal PLL and timing generation. |
| SDS | Serial Data Strobe | Output strobe synchronized to IOM-2 bit clock-enables precise sampling of parallel data on IOM-2 bus. |
| STB | Strobe Input | Active-low latch signal for parallel microcontroller interface-controls register write/read timing alignment. |
| INT | Interrupt Output | Open-drain interrupt request-asserted for HDLC frame completion, error conditions, or C/I events. |
| TRXEN | Transceiver Enable | Active-high control for S/T transceiver circuitry-allows power-gating during idle states. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated DPLL with jitter filtering | Meets ITU-T G.823 Class 3 jitter transfer and tolerance-ensures stable clock recovery without external loop filters. |
| Dual independent HDLC controllers | Separate D-channel and monitor channel engines-enables concurrent protocol processing without resource contention. |
| Programmable Layer-1 state machines | Four distinct operational modes (TE/LT-T/LT-S/NT) with configurable C/I codes-supports flexible deployment in diverse ISDN topologies. |
| IOM-2 interface with strobed timing | 8 MHz max clock with SDS/STB synchronization-guarantees deterministic register access and FIFO management timing. |
| S/T delay compensation logic | Hardware-calibrated compensation for TE/LT-T mode-removes need for software-based delay adjustment in time-critical activation 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 SLE66 | Lacks integrated DPLL; requires external clock recovery IC and separate HDLC controller. | Higher BOM cost and larger PCB footprint due to external components. | Prefer only when legacy SLICOFI ecosystem integration is required and board space is not constrained. |
| NEC µPD6376 | Supports only TE mode; no NT or LT-S functionality; no monitor channel HDLC. | Cannot be deployed in network termination or diagnostic equipment roles. | Select only for simple TE-only endpoints where multi-mode operation is unnecessary. |
Compared with PSB 21150 F V1.4, the SLE66 increases system complexity with external timing and protocol logic, while the µPD6376 restricts deployment to TE mode only-making the PSB 21150 uniquely suitable for multi-role ISDN infrastructure where mode flexibility, integrated timing, and diagnostic capability are essential.

FAQ
What ISDN standards does PSB 21150 F V1.4 comply with?
The PSB 21150 F V1.4 complies with ITU-T I.430 for physical layer S/T interface, I.441 for D-channel protocol, and G.823 for jitter performance. It implements all mandatory state transitions, C/I codes, and timing parameters defined for TE, LT-T, LT-S, and NT modes per I.430 Annex A–D.
Does PSB 21150 F V1.4 require an external crystal or oscillator?
Yes-it requires a 16.384 MHz fundamental-mode crystal or CMOS oscillator connected to CLKI/CLKO pins. This frequency is mandatory for generating the 4.096 MHz and 2.048 MHz clocks needed for B/D-channel bit timing and DPLL reference.
Can PSB 21150 F V1.4 operate in both TE and NT modes simultaneously?
No-it operates in one mode at a time, selected via MODED register configuration and external pin strapping (MODE0/MODE1). Mode switching requires full reset and reinitialization of all functional blocks including HDLC FIFOs and DPLL.
Is there driver or firmware support available for PSB 21150 F V1.4?
Infineon provided reference drivers for Windows 98/2000 and Linux 2.4 in the IPAC-X software development kit (SDK), including IOM-2 initialization routines, HDLC frame handlers, and C/I channel interpreters-all validated against DS1 V1.4 register maps.
