National Instruments 781320-01 Digital I/O Adapter Module for FlexRIO
National Instruments part number 781320-01 is an identifying part number for the NI-6583, a Digital I/O Adapter Module for FlexRIO with 32 Digital Bidirectional Channels and 200 MHz Clock Rate. This NI 781320-01 Adapter Module supports testing of digital waveforms up to 200 MHz. The module includes the NI SHC68-H1X38 cable, which breaks out each single-ended signal into two 0.1-inch header connectors—one for the signal and one for the ground. This cable facilitates easy connection of NI single-ended digital signals to various devices and circuits for interfacing, testing, or analysis purposes.
The digital I/O capabilities of the DDC A and DDC B on the FlexRIO platform offer a comprehensive set of features. DDC A includes a total of 35 digital I/O channels, comprising 32 single-ended data channels and 3 single-ended PFI (Programmable Function Interface) channels. DDC B provides 19 digital I/O channels, with 16 channels dedicated to differential data and 3 channels for differential PFI. Each channel allows individual direction control, with a minimal required direction change latency of 9 ns applicable to single-ended signals.
The module supports a single programmable I/O voltage level (VCC) ranging from 1.2 V to 3.3 V, with a nominal resolution of 10-bit for precise digital signal processing and analysis tasks. The NI 781320-01 module features both single-ended and differential channels that can operate concurrently. Single-ended signals and terminal blocks must be used with the VHDCI connector, while differential signals and terminal blocks require the use of the infinite-band connector. For both single-ended and differential channels, users can employ a flying leads cable specifically designed for NI separate cables, which need to be purchased separately.
The typical data rates for these digital I/O modules vary depending on the voltage level used. At 1.8 V, 2.5 V, and 3.3 V, the data rate reaches 300 Mb/s. When operating at 1.5 V, the data rate slightly decreases to 280 Mb/s, and at 1.2 V, it further reduces to 240 Mb/s. These rates indicate the maximum throughput at each voltage level, ensuring efficient digital signal processing and communication capabilities across different voltage ranges supported by the module.
