Product details
Overview
PEF 22552 E V1.1 from Infineon Technologies is a dual-channel E1/T1/J1 framer and line interface unit (LIU) with integrated analog switches, programmable frame alignment, and HDLC controllers. It supports long/short-haul line interfaces, crystal-less jitter/wander compensation per TR-62411 and ETS-TBR 12/13, and operates across -40°C to +85°C in PG-LBGA-160 package. Used in Node B line cards and SDH/SONET ADMs.
For engineers reviewing the PEF 22552 E V1.1 datasheet, PEF 22552 E V1.1 pinout, PEF 22552 E V1.1 application, or PEF 22552 E V1.1 equivalent, key selection criteria include dual-port E1/T1/J1 framing capability, software-programmable frame formats (E1 CRC Multi-frame, T1 ESF/F72), integrated clock generation (1.02–20 MHz reference), receiver sensitivity (-36 dB@772 kHz), and HDLC controller count (6 total, 3 per channel).
Technical Context
The device implements two independent ITU-T G.704-compliant framers with programmable multi-frame structures-E1 supports Double- and CRC Multi-frame; T1 supports F4, F12 (D4), ESF, and F72 (SLC96). Alarm handling includes detection and generation of LOS, AIS, and RAI with CRC-4 performance monitoring and PRBS generation/monitoring.
Its analog line interface integrates transmit impedance matching, software-configurable pulse shaping, and analog switches for E1 (75/120 Ω), T1 (100 Ω), and J1 (110 Ω) impedance matching or protection switching. Clock extraction and generation comply with ITU-T G.703 Sec. 13, and SSM generation/extraction is supported.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port E1/T1/J1 framer and LIU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEF 22554 | Same architecture, but includes integrated DELIC-compatible digital loop carrier interface and enhanced PCM routing | Targeted at digital loop carrier systems requiring PCM bus expansion beyond basic framer functionality | Select when PCM interface extension and DELIC co-processing are required alongside dual E1/T1 framing |
| PEF 22810 | Single-port E1/T1/J1 framer with identical analog front-end and clocking, but no HDLC controllers or SSM support | Designed for cost-sensitive, low-channel-count line cards where signaling processing is handled externally | Select when only framing and line interface are needed, and HDLC/CAS/SSM functions are offloaded to host processor |
Compared with PEF 22552 E V1.1, PEF 22554 adds PCM routing and DELIC compatibility for loop carrier integration, while PEF 22810 removes HDLC and SSM to reduce cost and complexity - choice depends on whether embedded signaling processing and synchronous timing traceability are required.

Does PEF 22552 E V1.1 support ANSI T1.403 Bit-Oriented Messages (BOM)?
Yes - it natively supports ANSI T1.403 BOM through its integrated HDLC controllers, which generate periodic performance reports and handle bit-oriented message formatting. This capability is used in T1-based remote access servers and digital loop carriers for maintenance and diagnostics.
Can PEF 22552 E V1.1 operate with a single 3.3 V supply only?
Yes - the device supports both dual-voltage (1.8 V I/O + 3.3 V analog/core) and single 3.3 V supply configurations. In single-supply mode, internal regulators manage voltage scaling for analog and digital domains, maintaining full functionality including HDLC, framing, and line interface performance.
Is JTAG boundary scan supported on PEF 22552 E V1.1?
Yes - the device includes IEEE 1149.1-compliant JTAG boundary scan for production testing and debug. The JTAG interface supports full pin visibility, register access, and interconnect testing without requiring additional test fixtures or probe points on the PCB.
