Product details
Overview
PEB 20571 F V3.1 from Infineon Technologies is a DSP-embedded Line and Port Interface Controller (DELIC-PB) designed for ISDN S/T interface termination and UPN/DECT physical layer interfacing in digital telephony systems. It integrates IOM-2000 transceiver, PCM, HDLC/GHDLC, A/µ-law conversion, and DMA mailbox units, supports 16-bit µP interface (Intel/Motorola mode), operates at 3.3 V supply, and delivers full-duplex 2B+D channel handling with integrated framing and synchronization logic.
For engineers reviewing the PEB 20571 F V3.1 datasheet, PEB 20571 F V3.1 pinout, PEB 20571 F V3.1 application, or PEB 20571 F V3.1 equivalent, key selection considerations include its dual-mode IOM-2000/UPN frame processing capability, dedicated GHDLC protocol engine for multi-point bus arbitration, on-chip DMA mailbox for zero-overhead data transfer, and support for DECT synchronization timing alignment - all critical for ISDN terminal adapter and cordless base station designs.
Technical Context
The PEB 20571 F V3.1 implements a hierarchical interface architecture: its IOM-2000 Transceiver Unit (TRANSIU) handles S/T physical layer signaling (LT-S/LT-T modes), UPN framing with LF/M/DC-balancing bits, and DECT sync alignment; the GHDLC unit provides hardware-accelerated HDLC with external DMA support, point-to-multipoint arbitration, and configurable buffer memory allocation.
It features a 16-bit parallel µP interface supporting Intel/Motorola timing, de-multiplexed/multiplexed bus modes, and DMA/non-DMA operation; the DSP Control Unit manages boot strap pin configuration, interrupt prioritization (including DELIC external interrupts), and runtime statistics - enabling tight integration with OakDSPCore® (OAK®) processors in voice/data gateway platforms.

Equivalent & Alternatives
The following parts are listed as comparable options for similar line interface controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEB 20570 V3.1 | DELIC-LC variant without DMA mailbox and GHDLC unit; supports only IOM-2000 and basic HDLC | Targeted at simpler ISDN terminal adapters without multi-point bus or high-throughput DMA requirements | Select when system uses single S/T port and does not require external DMA or multi-drop HDLC arbitration |
| Infineon TLE6240-2 | High-voltage line driver IC (not a controller); lacks DSP interface, protocol engines, and framing logic | Used only for analog line driving in conjunction with separate controller - not functionally substitutable | Not a functional alternative; only suitable as companion line driver if PEB 20571 F V3.1 is paired with external SLIC |
Compared with PEB 20570 V3.1, the PEB 20571 F V3.1 adds DMA mailbox and GHDLC for scalable multi-port ISDN systems; unlike TLE6240-2, it integrates full protocol stack and DSP interface - making it a complete line interface SoC rather than a peripheral driver.

FAQ
What is the difference between PEB 20571 F V3.1 and PEB 20570 V3.1?
The PEB 20571 F V3.1 (DELIC-PB) includes a DMA mailbox and GHDLC unit absent in the PEB 20570 V3.1 (DELIC-LC). This enables hardware-accelerated multi-point HDLC bus arbitration and zero-overhead data transfers via external DMA controller - critical for high-channel-count ISDN systems and DECT base stations with multiple handsets.
Does PEB 20571 F V3.1 support both Intel and Motorola µP interface timing?
Yes - the µP interface supports configurable Intel (80C86-style) or Motorola (68000-style) timing modes via strap pins (DS 2.1 Section 2.5). This allows seamless integration with either architecture without external glue logic, and supports both multiplexed and de-multiplexed bus configurations.
Can PEB 20571 F V3.1 operate standalone without an external DSP?
No - it is a DSP-embedded controller requiring an external OakDSPCore® (OAK®) or compatible DSP. The device lacks program memory and execution units; instead, it provides tightly coupled mailboxes, interrupt signaling, and DMA pathways for offloading physical layer tasks from the host DSP.
What clock frequency is required for DECT UPN synchronization?
A 16.384 MHz master clock applied to CLKIN is mandatory. The internal PLL derives the 4.096 MHz UPN clock (exactly 1/4 of input) and aligns UPN_DATA framing to DECT 10 ms superframe boundaries - meeting ETSI EN 300 175-2 timing accuracy requirements for base station operation.
