Description
The GT5930 programmable level I/O module eliminates the need to create custom interface circuits. The GT5930 module interfaces between the GT5150 and GT50-DIO TTL environment and the variable custom levels at the UUT. The GT5930 is a plug-in unit, and can be mounted on the GT5150 or the GT5900 I/O module carrier card. The GT5930 provides 32 channels of programmable level translation outputs combined with programmable level threshold inputs.
Architecture
The GT5930 employs the EDGE649 octal pin driver/receiver to provide programmable output and threshold levels common to all I/O channels. In addition to high and low I/O voltage levels, the logic threshold is fully programmable via three on-board DAC controlled variable power supplies. The 11V driver output and receiver input range allows a direct interface to TTL, ECL, CMOS (3 V, 5 V, and 8 V), and custom level circuitry.
Programming
Programming of the GT5930 Module is performed via the host. Programmable functions include:
- High and low I/O voltage levels
- Common threshold level
- Signal termination enable/disable
- I/O data direction
- Tri-state control
Applications
- IC testing
- Custom input and output levels
- Process control
