DIO - Multimode Digital Source/Capture

DIO

  • Multimode Digital Source/Capture module
  • Up to 50MHz data rate in low speed mode
  • Up to 200MHz data rate in high speed mode
  • 20-bit parallel / 24-bit serial capture capability
  • 256k x 16 pattern generator (low speed mode)
  • Programmable clock delays (high sp. mode)
  • Internal Clock generation up to 200MHz
  • External clock rate up to 400MHz
  • Programmable IO levels
  • For ATX series hardware platform

The DIO-200 is a multimode digital source and capture module. In Low Speed Mode, the DIO-200 provides a 20-bit parallel or 24-bit serial I/O capability running up to 50MHz. In High Speed Mode, the DIO-200 provides a 16-bit parallel I/O capability up to 200MHz.

In both Speed Modes, the Clock is generated by a low jitter PLL source that can generate clocks from 2kHz up to 200MHz. In addition an external clock can be provided.

The DIO-200 offers 8 Pattern Bits to the user for DUT synchronization and control. The remaining 8 Pattern Bits are used for control and synchronization of the analog source and capture instrumentation through the ATX backplane. This allows for coherent mixed-signal measurements improving the accuracy of your measurement without need for post-process windowing.
