Product details
Overview
PEF 22554 HT V2.1 from Infineon Technologies is a quad-channel E1/T1/J1 framer and line interface unit (LIU) with integrated analog switches, clock generation (1.02–20 MHz reference), and 12 HDLC controllers. It supports programmable frame formats (E1 CRC/D-MF, T1 ESF/F72), ITU-T G.704 alignment, and operates across -40°C to +85°C in PG-TQFP-144 package. Used in Node B line cards and SDH/SONET ADMs.
For engineers reviewing the PEF 22554 HT V2.1 datasheet, PEF 22554 HT V2.1 pinout, PEF 22554 HT V2.1 application, or PEF 22554 HT V2.1 equivalent, key selection criteria include four-port E1/T1/J1 framing capability, software-programmable line interface modes, integrated impedance-matching analog switches, and dual-voltage (1.8 V/3.3 V) operation for telecom line-card designs.
Technical Context
The device integrates four independent LIUs with configurable long/short-haul E1/T1/J1 physical layer support, each featuring receiver sensitivity of -36 dB@772 kHz and -43 dB@1024 kHz, plus programmable transmit pulse shaping per channel. Clock extraction and generation comply with ITU-T G.703 Sec. 13 and TR 62411 wander/jitter attenuation requirements.
It embeds 12 HDLC controllers (3 per channel) with 128-byte FIFOs, CAS signaling support, SS7 compatibility, and ANSI T1.403 BOM messaging. System bus data rate scales from 1.544 Mbit/s to 16 Mbit/s, with Intel®/Motorola® 8/16-bit parallel and SPI/SCI serial interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel E1/T1/J1 framer and LIU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEF 22554 E | Same silicon, packaged in PG-LBGA-160 (15×15 mm, 1.0 mm ball pitch) instead of PG-TQFP-144. | Preferred for high-density, thermally constrained designs where BGA reflow and X-ray inspection are available. | Select when board layout favors fine-pitch BGA and thermal dissipation via PCB ground plane is prioritized. |
| PEF 22553 HT | Dual-port variant (2× E1/T1/J1) with identical feature set, pinout, and software compatibility. | Suitable for lower-port-count line cards or cost-sensitive applications requiring half the channel density. | Choose when only two E1/T1 ports are needed-reduces power consumption and simplifies routing without sacrificing functionality. |
Compared with PEF 22554 E, the HT V2.1 offers identical electrical performance but easier hand-soldering and optical inspection due to TQFP leads; compared with PEF 22553 HT, it doubles port count at marginally higher power (150 mW/channel), enabling full four-port line-card consolidation.
