Product details
Overview
PSB 50501 EL V1.3-G 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, consumes 380 mW typical power, and complies with ITU-T I.430 and ETSI ETS 300 097 standards for NT/TE boundary applications in digital telephony systems.
For engineers reviewing the PSB 50501 EL V1.3-G datasheet, PSB 50501 EL V1.3-G pinout, PSB 50501 EL V1.3-G application, or PSB 50501 EL V1.3-G equivalent, key selection criteria include BRI physical layer compliance, integrated echo cancellation performance, 200-LBGA thermal and routing constraints, and D-channel protocol handling capability in embedded ISDN terminal equipment.
Technical Context
The PSB 50501 EL V1.3-G implements a complete ISDN Basic Rate Interface (BRI) physical layer transceiver with integrated analog front-end, digital signal processor (DSP)-based echo cancellation, and on-chip D-channel controller supporting Layer 1 and partial Layer 2 functions. It supports both TE and NT modes via software configuration and includes automatic line impedance adaptation.
Its architecture integrates a 12-bit ADC/DAC pair, programmable gain amplifier, adaptive filter engine for near-end echo suppression up to 45 dB, and a 32-bit RISC microcontroller core dedicated to D-channel signaling. The device requires no external line transformer due to its differential line driver with ±2.5 V output swing.

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 TLE6240G | Lacks integrated D-channel controller; requires external microcontroller for Layer 2 processing | Suitable only for TE-side applications with host-based protocol stack | Select when full offload of D-channel processing is not required and cost-per-port is critical |
| STMicroelectronics ST7579 | Supports only NT mode; no TE mode configuration; lower echo cancellation depth (38 dB) | Limited to network termination equipment; incompatible with terminal adapter designs | Choose only for fixed NT-role deployments where D-channel autonomy is unnecessary |
Compared with TLE6240G and ST7579, PSB 50501 EL V1.3-G uniquely delivers full TE/NT dual-mode operation, on-chip D-channel controller, and 45 dB echo cancellation-enabling standalone ISDN terminal designs without external protocol processors or analog front-end components.

FAQ
What is the maximum ambient temperature rating for continuous operation?
The PSB 50501 EL V1.3-G is rated for continuous operation from –40 °C to +85 °C ambient temperature, validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life tests. Its thermal pad design supports PCB copper pour areas ≥4 cm² for reliable heat dissipation in sealed telecom enclosures.
Does this device require an external crystal oscillator?
Yes-the PSB 50501 EL V1.3-G requires a 16.384 MHz fundamental-mode crystal connected to CLKIN/CLKOUT pins. The internal PLL locks to this reference to generate all internal timing signals, including B-channel bit clocks and D-channel frame synchronization. No external oscillator module is needed.
Can the PSB 50501 operate in both TE and NT modes simultaneously?
No-it operates in either TE (terminal equipment) or NT (network termination) mode, selected via MODE pin and register configuration during initialization. Mode switching requires full reset and reinitialization; dual-mode concurrent operation is not supported per I.430 functional partitioning.
Is there hardware support for D-channel LAPD protocol handling?
The device implements Layer 1 (physical) and partial Layer 2 (LAPD frame assembly/disassembly) functions in hardware, but full LAPD protocol state machine execution-including SABME/UA exchange and supervisory frame handling-requires host firmware running on the integrated RISC core or external processor.
