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. ## Technical Specifications • Core Technology: IT9010 VXIntegrator chip • Interface Type: Register-based VXI interface • Board Area: 13.5 square inches • Board Thickness: 0.062 inches • Component Height: Up to 0.30 inches • Module Compatibility: B-size, C-size, and D-size VXI modules • Hole Spacing: 0.100 inches • Hole Diameter: 0.042 ± 0.003 inches ## Electrical Characteristics • Supply Voltage: 4.75 V to 5.25 V (nominal 5.0 V) • Input Logic Levels: Vih 2.2 V (min), Vil 0.8 V (max) • Supply Current: 300 mA @ 5 V • Output Current Ratings: Standard ±40 mA, Medium Drive ±40 to +80 mA, High Drive ±90 to +180 mA, Open-Collector -128 mA, Bidirectional I/O1 ±48 mA, Bidirectional I/O2 ±128 mA • Absolute Maximum Supply Voltage: GND - 0.5 V to 6.0 V • Operating Temperature: 0 °C to +50 °C • Storage Temperature: -40 °C to +70 °C ## Key Features • High current buffers for direct VME/VXI backplane signal driving • Complete VXI specification register implementation • Interrupt generation circuitry • Compact footprint preserving significant design space on host module ## Compatibility & Integration Designed for VXIbus-compliant systems and compatible with VXI prototyping modules such as the Interface Technology BB9210.
