Interface Technology DT9110 Daughter Card

The Interface Technology DT9110 is a daughter card that adds register-based VXI interface capability to VXIbus data acquisition systems. Built around the IT9010 VXIntegrator chip, it integrates essential VXI interface elements into a compact 13.5 square inch form factor compatible with B-size, C-size, and D-size VXI modules. The card implements all VXI specification configuration registers—including Device Dependent and A24/A32 VMEbus registers—and provides high current buffers for direct VME/VXI backplane signal driving plus integrated interrupt generation circuitry. Supply current is 300 mA @ 5 V. The DT9110 operates from 0 °C to +50 °C and is suitable for OEM integration, custom development, and laboratory or industrial applications requiring VXI protocol support.
