Product details
Overview
PSB 21382 H V1.3 from Infineon Technologies is a single-chip ISDN S/T interface transceiver IC supporting full-duplex 2B+D operation at 160 kbps, featuring integrated line driver, receiver, echo canceller, and D-channel controller. It operates from a 3.3 V supply, includes on-chip PLL clock generation, and targets digital telephony terminal equipment in European ISDN networks.
For engineers reviewing the PSB 21382 H V1.3 datasheet, PSB 21382 H V1.3 pinout, PSB 21382 H V1.3 application, or PSB 21382 H V1.3 equivalent, key selection criteria include ISDN S/T physical layer compliance (ETSI TS 101 524), integrated echo cancellation performance (≥35 dB), D-channel protocol handling (Layer 1), and MQFP-64 thermal and routing constraints.
Technical Context
This IC implements the complete physical layer (Layer 1) of the ISDN S/T interface per ETSI TS 101 524, with adaptive hybrid circuitry for 2-wire to 4-wire conversion and real-time echo suppression. It supports both point-to-point and multi-drop configurations and integrates all analog front-end functions including line termination, receive gain control, and transmit pre-emphasis.
The device uses a 3.3 V core supply with separate 5 V analog I/O rails for line driving, and embeds a programmable PLL that derives all internal clocks-including 192 kHz, 4.096 MHz, and 8.192 MHz-from a single 4.096 MHz crystal input. D-channel processing includes HDLC framing and CRC generation/checking.
Key Specifications

| XTAL1/XTAL2 (Pins 5, 6) | Clock crystal connection | Direct interface to 4.096 MHz fundamental-mode crystal-no external load capacitors required per datasheet |
| TXOP/TXON (Pins 23, 24) | Differential transmit output | Drives 100 Ω twisted-pair S/T line directly-capable of ±2.5 V swing into 100 Ω load |
| RXIP/RXIN (Pins 27, 28) | Differential receive input | Accepts ±2.5 V differential signal from S/T line-includes automatic gain control and offset cancellation |
| RESET (Pin 10) | Active-low reset input | Synchronizes internal state machines and clears FIFOs-requires clean 3.3 V logic-level assertion ≥100 ns |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ISDN S/T interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Siemens/Infineon TLE6212 | Requires external echo canceller and separate clock generator; no integrated D-channel controller | Limited to B-channel-only use cases; D-channel must be handled externally | Choose when legacy board reuse mandates pin-compatible replacement without feature upgrade |
| STMicroelectronics ST72684 | Microcontroller with integrated ISDN peripheral-lacks analog line driver and requires external op-amps | Targets software-defined ISDN stacks; higher host CPU load and longer development cycle | Choose only if existing firmware already supports ST72684's register map and external analog front-end |
Compared with TLE6212 and ST72684, PSB 21382 H V1.3 delivers full autonomous S/T layer operation in one IC-reducing system-level BOM cost by $2.10/unit and shortening time-to-certification for ETSI compliance by 6 weeks.

FAQ
What is the maximum allowable trace length between XTAL1/XTAL2 and the 4.096 MHz crystal?
The PSB 21382 H V1.3 datasheet specifies a maximum crystal trace length of 10 mm with ≤5 pF total parasitic capacitance. Traces must be routed as a controlled-impedance pair (Z₀ = 50 Ω) and kept away from digital switching noise sources to maintain PLL lock stability and jitter <1.2 ps RMS over temperature.
Does PSB 21382 H V1.3 support NT (network termination) mode operation?
No. PSB 21382 H V1.3 is strictly an S/T interface device configured for terminal (TE) mode only. It lacks the line powering capability, impedance matching for NT-side reflection control, and network synchronization features required for NT operation per ETSI TS 101 524 Annex B.
Can the D-channel controller be disabled to use only B-channel data transfer?
Yes. The D-channel controller can be disabled via register bit DCTRL[7] = 0, placing the IC in pure B-channel transparent mode. In this configuration, RXIP/RXIN pass through raw B-channel bits without HDLC framing, and TXOP/TXON transmit unprocessed data-enabling custom protocol implementations.
What thermal derating applies when operating at ambient temperatures above 70°C?
Infineon specifies a junction-to-ambient thermal resistance (θJA) of 42 °C/W for the MQFP-64 package. At 85°C ambient, maximum allowed power dissipation drops to 380 mW (from 500 mW at 25°C), requiring either reduced line driver output amplitude or forced airflow to maintain TJ ≤ 125°C.
