Description
The NI-5771 is a reconfigurable FPGA digitizer, with a part number of 195815A-02L, designed for use in PXI systems. It features 2-channel inputs, making it suitable for applications requiring simultaneous sampling of multiple signals. The digitizer boasts a 900 MHz bandwidth, ensuring high fidelity in signal acquisition and analysis.
With an 8-bit resolution, the NI-5771 provides precise digital representation of analog signals, allowing for detailed analysis and processing. The sampling rate varies depending on the number of active channels; when a single channel is used, the device can sample at an impressive rate of 3.0 GS/s, while with both channels active, the sampling rate is 1.5 GS/s.
The analog input voltage range of the device is from -0.675 V to 0.675 V, accommodating a wide range of signal amplitudes. For users looking to interface with FPGAs, the NI-5771 is compatible with both Virtex-5 and Kintex-7 FPGAs, offering flexibility in system design and implementation.
Connectivity options include 2 SMA type connectors (AI 0 and AI 1) for analog inputs, ensuring reliable and high-quality connections. The device also features an internal sample clock of 1.5 GHz, VCXO type, providing a stable timing reference for sampling operations. Additionally, CLK IN/OUT connectors are available, supporting synchronization with external devices.
For auxiliary input/output, the NI-5771 utilizes an HDMI connector, though it’s noteworthy that this is not for HDMI interface purposes. Moreover, the device includes 12 bi-directional channels (4 PFI and 8 DIO), further expanding its utility in complex system configurations and signal processing tasks.
