ISDN-PRI Pulse Interface Modules Data Sheet

Category: Electronics, Pulse Electronics Corporation, Transformers

Overview of TL/EL/CEPT/ISDN-PRI Pulse Interface Modules

The data sheet provides detailed information about TL/EL/CEPT/ISDN-PRI Pulse Interface Modules designed for dual SMT T1/E1 ports with an extended temperature range. These modules are optimized for electromagnetic compatibility (EMC) performance and comply with RoHS specifications. The datasheet states that the modules include proprietary technology for enhanced reliability and are recognized to the UL 1950 standard for safety.

Key Features and Specifications

Each module comprises four transformer modules matched to leading transceiver integrated circuits (ICs) and have an extended operating temperature range of -40°C to +85°C. The transformers can come with optional common mode chokes on both transmit and receive channels. Electrical specifications, including turns ratios, open circuit inductance (OCL), and direct current resistance (DCR) for primary and secondary pins, are provided for different models with various schematic types.

Design and Compliance

Patented Interlock Base construction enhances the reliability of the modules, which meet the RoHS peak reflow temperature rating of 245°C. Specific models are suited for extended temperature ranges, and open-circuit inductance is guaranteed even at -40°C. The data sheet mentions that standard packaging includes anti-static tubes, with an option for Tape & Reel packaging by adding a “T” suffix to the product number.

Applications and Performance

Designed specifically for 1.544 Mbps (T1), 2.048 Mbps (CEPT), and ISDN Primary Rate Interface (PRI) applications, these modules align with ITU-T G.703 and other standards concerning pulse waveform, return loss, and balance. They excel in characteristics including return loss, balance, common mode rejection ratio (CMRR), and crosstalk attenuation, which contribute to a high-quality signaling environment crucial for telecom and data communications systems.

The performance warranty is limited to the specified parameters, and data is subject to change without notice. For additional information and technical inquiries, Pulse Electronics contact details are provided for various global regions, ensuring that customers have access to local support.

Technical and Service Information

Materials used in these modules are UL 94V-0 approved, and the products meet the requirements of the Needle Flame Test according to IEC 695-2-2. The data sheet also includes mechanical schematics, suggested pad layout, packaging information, and regional headquarters’ contact details, offering comprehensive support for integration and implementation.
