Description
The PXIe-7868 is a multifunction reconfigurable I/O module, categorized under the PXI R Series. It carries part numbers 144006A-05L, PXIe-7868R, and 785571-01. This module is powered by a Kintex-7 325T FPGA and is equipped with 512 MB of DRAM memory.
For analog signal processing, the module provides 18 Analog Outputs (AO) channels and 6 Analog Inputs (AI) channels. In terms of Digital Inputs/Outputs (DIO), it boasts 48 channels. These capabilities ensure a wide range of application uses, from simple signal processing to complex control systems.
The module’s sampling rate reaches up to 1 MS/s, allowing for high-speed data acquisition and processing. The external clock input, labeled EXTCLKIN, enables synchronization with external devices or systems.
Digital I/O connectivity is divided into two connectors: the first connector supports 16 low-speed channels capable of up to 10 MHz, while the second supports 32 high-speed channels that can handle up to 80 MHz. The trace impedance for the DIO Connector 1 is specified at 50 Ω, ensuring signal integrity for high-speed data communication.
Protection features include safeguards against overvoltage, undervoltage, and overcurrent scenarios, ensuring the longevity and reliability of the module. Additionally, the power-on state configuration is available for any line, offering flexibility in system startup conditions.
The digital I/O voltage logic is compatible with LVTTL and LVCMOS standards, with a fixed 3.3 V logic level, ensuring compatibility with a wide range of digital devices and systems.
