National Instruments 778747-01 Single-Ended Digital I/O Accessory 

National Instruments part number 778747-01 is an identifying part number of the SMB-2163, a Single-Ended Digital I/O Accessory designed for NI digital waveform generator/analyzer modules. This accessory is equipped with 32 single-ended DIO channels and 3 programmable function interface (PFI) channels, providing a robust solution for digital signal applications. The SMB-2163 supports connectivity to up to 32 bidirectional digital data channels (DIO 0-31) and includes two dedicated clock channels: STROBE for external sample clock input and DDC CLK OUT for exporting the sample clock signal.

The SMB-2163 accessory features 37 SMB jack connectors for signal connections and one 68-pin Digital Data & Control (DDC) connector for seamless integration with NI modules. This accessory is engineered to minimize signal distortion, with a typical propagation delay of 1.2 ns and a channel-to-channel skew of ±35 ps. It also features a typical trace characteristic impedance of 50 Ω, ensuring optimal signal integrity across all channels.

With dimensions of 30.5 cm × 4.5 cm × 26.5 cm, the SMB-2163 is designed for versatile deployment in various lab and test environments. The accessory includes a shield ground lug for enhanced EMI protection and additional grounding options. While it is compatible with NI's single-ended digital waveform generator/analyzer modules, it does not support differential digital signals or NI 6533/6534 products.

The 778747-01 is CE compliant, meeting the necessary regulatory standards for global markets. In line with National Instruments' commitment to environmental responsibility, this accessory is designed with consideration for reducing hazardous substances and ensuring proper end-of-life recycling, as evidenced by its WEEE compliance.
