Product details
Overview
PEB3165FV11XT from Infineon Technologies is a single-chip ISDN S/T interface transceiver IC supporting full-duplex 2B+D operation at 160 kbps, compliant with ITU-T I.430 and ETSI EN 300 012-1. It integrates line driver, receiver, codec, PLL clock recovery, and D-channel controller in TQFP-64 package, used in ISDN terminal adapters and NT1 devices for European PSTN integration.
For engineers reviewing the PEB3165FV11XT datasheet, PEB3165FV11XT pinout, PEB3165FV11XT application, or PEB3165FV11XT equivalent, key selection criteria include I.430 physical layer compliance, integrated D-channel HDLC controller, on-chip 8-bit μP interface, and support for both TE and NT operating modes in a single device.
Technical Context
The PEB3165FV11XT implements a complete ISDN S/T reference point physical layer (Layer 1) with integrated analog front-end, digital signal processor, and microcontroller interface logic. It performs line coding (2B1Q), echo cancellation, adaptive equalization, and D-channel frame synchronization per I.430 Annex A.
It supports automatic mode detection (TE/NT), programmable line build-out (LBO), and provides status monitoring via interrupt and register flags. The embedded D-channel controller handles HDLC framing, CRC generation/checking, and link-layer signaling for Layer 2 operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ISDN S/T physical layer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI32260-C-FM | Lacks integrated D-channel controller; requires external MCU for LAPD handling | Suitable only for TE-mode devices with host-based protocol stack | Select when full D-channel offload is unnecessary and cost-per-channel is prioritized |
| MAX13212E | Supports only NT-mode operation; no auto TE/NT detection | Restricted to network-side deployments with fixed line polarity | Choose for simplified NT1 designs where mode flexibility is not required |
Compared with SI32260-C-FM and MAX13212E, the PEB3165FV11XT uniquely combines full TE/NT dual-mode operation, embedded D-channel controller, and programmable LBO - enabling single-device support for both terminal and network termination roles without firmware or hardware reconfiguration.

FAQ
What is the maximum supported loop length for PEB3165FV11XT in NT-mode operation?
The PEB3165FV11XT supports up to 4 km loop length in NT-mode using its programmable line build-out (LBO) feature, which provides four adjustable output levels (0 dB to 12 dB). This is validated per ETSI EN 300 012-1 Annex A for 2B1Q signaling under worst-case attenuation conditions.
Does PEB3165FV11XT require an external crystal oscillator?
No. The device integrates a PLL-based clock recovery circuit that derives all required timing signals-including 192 kHz and 4.096 MHz clocks-directly from the incoming 2B1Q data stream. No external crystal or oscillator is needed for basic S/T interface operation.
Can PEB3165FV11XT operate in both TE and NT modes simultaneously?
No. It operates in either TE or NT mode, automatically detected at power-up based on line voltage polarity and timing characteristics. Mode selection is not user-configurable via software or pins; the device self-identifies and configures internal registers accordingly.
What is the function of the VCC_LIN pin?
VCC_LIN supplies 5 V to the high-current 2B1Q line driver stage. It must be decoupled with ≥10 µF low-ESR capacitor near the pin to maintain signal integrity and prevent distortion during peak current transients in long-loop transmission.
