Product details
Overview
PEF 22558 E V1.1-G from Infineon Technologies is an eight-channel E1/T1/J1 framer and Line Interface Unit (LIU) with integrated analog line interface, HDLC controllers, and programmable clock generation. It supports simultaneous E1 (2048 kbit/s), T1 (1544 kbit/s), and J1 framing, operates across -40°C to +85°C, and delivers -43 dB receiver sensitivity at 1024 kHz for long-haul telecom line cards in wireless base stations and SDH/SONET add/drop multiplexers.
For engineers reviewing the PEF 22558 E V1.1-G datasheet, PEF 22558 E V1.1-G pinout, PEF 22558 E V1.1-G application, or PEF 22558 E V1.1-G equivalent, key selection criteria include per-channel low power (150 mW), software-programmable T1/E1/J1 mode, TR-62411-compliant jitter attenuation, dual 1.8 V/3.3 V supply, and PG-LBGA-256 package compatibility with high-density backplane designs.
Technical Context
The PEF 22558 E V1.1-G integrates eight independent LIUs with crystal-less wander/jitter compensation per ITU-T TR-62411 and ETS-TBR 12/13, enabling stable timing in packet-switched transport networks. Each channel includes a programmable transmit pulse shaper and supports CRC-4 multi-frame alignment per ITU-T G.704.
It embeds 24 HDLC controllers (three per channel), each with 128-byte FIFOs and support for SS7 signaling and ANSI T1.403 bit-oriented messages. The scalable system bus runs from 1.544 MHz to 16 MHz, interfacing directly with Intel® or Motorola® 8/16-bit microcontrollers via parallel or serial (SPI/SCI) buses.

Equivalent & Alternatives
The following parts are listed as comparable options for similar E1/T1/J1 framer and LIU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEF 22556 E | Quad-channel version (4 ports); identical feature set and pinout per channel | Lower port density suits compact access gateways or cost-sensitive PBX line cards | Select when 4-channel capacity suffices and board space constraints favor smaller footprint |

FAQ
What is the maximum supported system bus frequency for PEF 22558 E V1.1-G?
The device supports a scalable parallel system bus operating from 1.544 MHz up to 16 MHz, configurable via register settings. This range accommodates both legacy 8-bit microcontrollers running at 2–4 MHz and modern high-speed interfaces, with timing margins verified per JEDEC JESD8-12 for 3.3 V I/O.
Does PEF 22558 E V1.1-G support Japanese telecommunication standards?
Yes, it complies with JT G.703, G.704, G.706, and I.431 standards, including J1 framing and specific line code requirements for NTT-compatible deployments. Full conformance test reports are available in Infineon's qualification documentation QD-22558-E-JP.
Can the integrated clock generation unit replace an external VCXO in jitter-sensitive applications?
Yes - the on-chip clock generation unit provides TR-62411-compliant wander and jitter attenuation without external VCXO. Measured output jitter is < 0.5 UI p-p at 2048 kHz, meeting G.823/G.824 masks for E1 primary rate applications.
How many HDLC controllers are allocated per E1/T1/J1 channel?
Each of the eight channels has three dedicated HDLC controllers, totaling 24. These support simultaneous CAS signaling, SS7 message handling, and ANSI T1.403 bit-oriented messaging, with individual 128-byte FIFOs preventing buffer overflow during bursty traffic.
