The CION Module™/FXT114S was specifically developed for the integration in test fixtures and enables the structural test of high-speed differential interfaces with IEEE-Std. 1149.1 compliant test resources. The digital low-cost module provides 114 parallel I/O channels with IEEE-Std. 1149.1. 50 of those channels also support IEEE-Std. 1149.6. The CION Module™/FXT114S provides 64 single-ended test channels, controlled by GOEPEL electronic's CION™ ASIC devices. All channels are independently controllable as Input/Output/Tristate and the I/O voltage can be programmed in groups. Special safety measures, such as the CION's 'UNSTRESS' feature, protect the Unit Under Test (UUT) against damage in case of shorts.
