National Instruments PCIe-7820 Digital Reconfigurable I/O Device

The PCIe-7820 is a Digital Reconfigurable I/O Device from NI, which is available under the part number 785361-01. This device has a Kintex-7 160T FPGA. The NI PCIe-7820 includes a high count of digital channels, with 128 channels capable of operating in either direction. This model also comes with four input channels. This device enables the user to extract the clock through an external source for different operational needs. The NI PCIe-7820 Digital Reconfigurable I/O Device supports a high clock rate, with a maximum value of 80 MHz.

The NI PCIe 7820 device can be used in many important applications. These applications include simulation for different types of sensors. This model offers the generation of waveforms at a high speed, along with the capability to conduct HIL (Hardware in the Loop) testing. In addition, the user can control or select most of the parameters on this device by using software. This device has a default setting of 3.3 volts for the voltage in software. The operations of this model are compatible with various logic families, including LVTTL and LVCMOS.

The maximum value of output DC current for each channel is 4 mili-amperes. The value for the sink current of the device is also 4 mili-amperes. The PCIe 7820 Digital Reconfigurable I/O Device has an input impedance of fifty ohms. The pulse width of the device for the I/O has the minimum value of 6.25 Nano-seconds. The minimum value of the sampling period is five Nano-seconds.
