Figure 2-5. PCI-MIO-16XE-50 Block Diagram
The following major components make up the PCI E Series boards:
• PCI bus interface circuitry with Plug and Play capability (MITE)
• Analog input circuitry
• Analog trigger circuitry
• Analog output circuitry
• Digital I/O circuitry
• Timing I/O circuitry (DAQ-STC)
• RTSI bus interface circuitry
The internal data and control buses interconnect the components. Notice
that the DAQ-STC is the timing engine that provides precise timing signals
for the analog input and output operations. The timing I/O circuitry
information in this manual is skeletal in nature and is sufficient in most
cases. For register-level programming information, refer to the DAQ-STC
Technical Reference Manual.
