NI PXIe-6612

Product catalog summary

Specifications Overview
The NI PCIe/PXIe-6612 device operates optimally at 25°C after a 15-minute warm-up. It includes 40 digital I/O channels, each configurable as input or output, with input voltage protection ranging from -3 V to 8 V and an output impedance of 75 Ω.

Digital I/O and Waveform Functionality
Waveform generation is facilitated through Port 0, supporting a sample size of up to 32 bits. The FIFO capacity is 2,047 samples for digital output and 255 samples for digital input. Sample clock frequencies can vary from 0 to 10 MHz, influenced by system and bus activity.

Timing I/O Functionality
PFI terminals allow for static digital I/O and timing signals, with programmable debounce filter settings for high and low transitions.

Electrical Characteristics
The device accepts input high voltages from 2 V to 5.25 V and input low voltages from 0 V to 0.8 V. It supports various counter measurements, including frequency and edge counting.

Counters/Timers
Equipped with 8 counters/timers, the device offers a 32-bit resolution, supporting frequency measurement up to 100 MHz and edge counting with prescaling options.

Frequency Generator and PLL
Includes one frequency generator channel with base clocks of 100 kHz, 10 MHz, and 20 MHz, with a PLL that locks to a 100 MHz timebase.

Bus Interface and Power Requirements
The NI PCIe-6612 is compatible with x1, x4, x8, and x16 PCI Express slots, while the NI PXIe-6612 fits PXI Express slots. Power requirements are 4.3 W maximum for +3.3 V and 6.0 W maximum for +12 V.

Environmental and Safety Standards
Operational temperature ranges from 0 to 55°C, compliant with IEC 61010-1 safety standards, and meets EMC standards such as EN 61326-1 and FCC Part 15B.

Environmental Management
NI adheres to environmentally responsible manufacturing, complying with WEEE directives for recycling electronic equipment.

Pinout Diagram
The document includes a pinout diagram for the NI 6612, detailing pin numbers and functions, such as PFI connections, CTR sources, gates, and outputs, along with ground connections. Notes specify that R GND pins are not connected to ground with an SH68-68-D1 shielded cable but are connected to D GND with an R6868 ribbon cable. Reserved pins should not be used as they are weakly pulled down to D GND.
