iQor-Advanced Telecommunications Computing Architecture (ATCA) Power Interface Modules

Telecom ATCA Modules

Advanced Telecommunications Computing Architecture (*ATCA®) Power Interface Modules

The iQor Power Interface Modules integrate all features required by the Advanced TCA Base Specification for a frame board power entry into a Quarter-Brick footprint. Minimal external components are required for all the key functions. The product family provides efficient utilization of hold-up capacitance. A full feature module with I2C interface is also available.
