PXIe-7903 Specifications

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical specifications describe the performance met by a majority of models.
  • Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.
  • Measured specifications describe the measured performance of a representative model.

Specifications are Typical unless otherwise noted.

Conditions

Specifications are valid under the following conditions unless otherwise noted.

  • Ambient temperature of 0 °C to 40 °C .
  • Installed in chassis with slot cooling capacity ≥82 W.

Reconfigurable FPGA

The PXIe-7903 provides a XCVU11P FPGA with characteristics shown in the following table.

Table 3. XCVU11P FPGA Characteristics
Characteristics XCVU11P
System Logic Cells 2,835 K
DSP slices (27 × 18 multiplier) 9,216

Note The list above depicts the total number of FPGA resources available on the part. The number of resources available to the user is slightly lower, as some FPGA resources are consumed by board-interfacing IP for PCI Express, device configuration, and various board I/O.
