Pulse Engineering Inc., a Technitrol company, and Intel Corp. have jointly developed a dual surface-mount transformer protection module for T1/E1 applications.

Fully matched and compatible with Intel's 3108 LIU, the T9050 dual-port T1/E1 line-interface module offers both line-side and chip-side protection, providing customers with a complete circuit-protection solution.

It protects ICs used in voice gateways, wireless basestations, WANs, digital access cross-connect systems, channel banks and switches.

With integrated magnetics and protection circuitry, this module is said to use up to 60 percent less board space, thereby reducing production costs, component count and engineering design time, according to Pulse.

The module integrates transformers for high-potential isolation, common mode chokes for EMI filtering, IC side-protection circuitry to suppress low-voltage transients, and line-side protection circuitry for surge protection.

The module provides the required 1.5kVrms line isolation and protects the high-speed data interfaces from overvoltages caused by ESD and electrical fast transients.

The dual-port line-interface module is designed to meet the major surge immunity and electrical safety standards, including Telcordia GR 1089, FCC Part 68 and UL 1950.

The units are currently available in tube packaging as well as tape and reel, with prices starting at $19.50 per unit in quantities of 5,000. Volume discounts are available. Lead time is four to six weeks. Contact Pulse directly for samples.
