Product details
Overview
PEF 22554 E V2.1 from Infineon Technologies is a quad-channel E1/T1/J1 framer and line interface unit (LIU) with integrated analog switches, crystal-less jitter/wander compensation per TR-62411 and ETS-TBR 12/13, and programmable frame alignment for 2.048/1.544 Mbit/s. It supports four independent long/short-haul line interfaces 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 22554 E V2.1 datasheet, PEF 22554 E V2.1 pinout, PEF 22554 E V2.1 application, or PEF 22554 E V2.1 equivalent, key selection criteria include ITU-T G.703 Sec. 13 clock extraction/generation, software-programmable T1/E1/J1 framing, PRBS generation/monitoring, CRC-4 performance monitoring, and dual-voltage (1.8 V/3.3 V) operation support.
Technical Context
The device integrates four independent framer/line interface channels, each with HDLC controllers (three per channel), CAS signaling support, and SSM generation/extraction. Frame alignment complies with ITU-T G.704 for E1 (Double-/CRC Multi-frame) and T1 (F4, ESF, F72), with alarm detection for LOS, AIS, and RAI.
Analog line interface includes programmable transmit pulse shaping, receiver sensitivity of -36 dB@772 kHz and -43 dB@1024 kHz, and integrated analog switches for impedance matching (E1-75/120 Ω, T1-100 Ω, J1-110 Ω) and protection switching - functional only in PG-LBGA-160 package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar framer and line interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEF 22554 HT | PG-TQFP-144 package; lacks integrated analog switches for protection switching | Suitable for fixed-impedance E1-only deployments where protection switching is not required | Select when board space allows larger TQFP footprint and analog switch functionality is unnecessary |
| PEF 22810 | Single-channel E1/T1 framer; no integrated analog switches; lower power (95 mW/channel) | Targeted at low-density line cards or evaluation systems requiring per-channel design flexibility | Select when scalability to four channels is not needed and system-level protection switching is handled externally |
Compared with PEF 22554 HT and PEF 22810, the PEF 22554 E V2.1 uniquely delivers four-channel integration with on-die analog switches enabling both impedance matching and protection path switching - critical for carrier-class redundancy in Node B and ADM line cards.

FAQ
What clock sources does PEF 22554 E V2.1 support?
PEF 22554 E V2.1 accepts any reference clock from 1.02 MHz to 20 MHz on its CLKIN pin. This wide range eliminates the need for dedicated crystal oscillators and allows flexible clock tree design using existing system clocks, including those derived from Ethernet PHYs or packet processors.
Does PEF 22554 E V2.1 support both E1 and T1 framing simultaneously?
Yes - each of the four channels can be independently configured for E1, T1, or J1 framing via software. Supported formats include E1 Double-/CRC Multi-frame and T1 F4, ESF, and F72 (SLC96), enabling mixed-standard line cards without hardware changes.
Is the integrated analog switch available in all packages?
No - the integrated analog switch for impedance matching and protection switching is functional only in the PG-LBGA-160 package (PEF 22554 E). It is not implemented in the PG-TQFP-144 variant (PEF 22554 HT), as confirmed in Infineon's Product Summary documentation.
How is jitter and wander managed without an external crystal?
The device implements crystal-less wander and jitter attenuation per TR-62411 and ETS-TBR 12/13 using an internal digital phase-locked loop and adaptive filtering. This achieves ±50 ppb frequency accuracy and <1.5 UI peak-to-peak jitter at the output, meeting G.703 Sec. 13 requirements.
