National Instruments PXIe-6672 Synchronization Module
The National Instruments PXIe-6672 (Part Number: 780063-01) is a Synchronization Module. This module has the capability to drive the PXI star trigger lines, import and export PXI backplane clocks and triggers, produce a high-stability resolution direct digital synthesis (DDS) clock, and create a high-stability temperature-remunerated crystal oscillator (TCXO) 10 MHz Reference Clock for arrangement. The NI PXIe-6672 Synchronization Module enables the user to synchronize different PXI Express frameworks, synchronize a PXI Express framework with outer instruments and equipment, and increment the precision of devices inside a PXI Express framework.
The National Instruments PXIe-6672 Synchronization Module can create two sorts of clock signals. The main clock is created by utilizing the locally available DDS chip, while the second is produced with an exact 10 MHz oscillator. The frequency tuning word is a number that indicates the desired frequency. On each master clock cycle, the frequency tuning word is added to the accumulator, which moves over when it gets to its most extreme esteem. The accumulator esteem is utilized to get a point in the sine-lookup table, which is changed over to an analog voltage by the DAC. For instance, if the sine table is 128 focuses in length and the frequency tuning word is one, the accumulator takes 128 clock cycles to output one sine wave. If the user decides to alter the frequency tuning word to 3, the accumulator steps through the sine table three times as quick and outputs a sine wave in 128/3, or 42.6, clock cycles.
The maximum power requirements of the PXIe-6672 are 800 mA for +3.3 V, and 700 mA for +12 V. The environmental specifications of the device include an operating temperature range of 0 to 55 °C and a storage temperature range of –40 to 71 °C. These temperature ranges were tested in accordance with the IEC-60068-2-1 and IEC-60068-2-2 specifications, and the meet the MIL-PRF-28800F Class 3 low temperature limit. The device weighs in at .0.459 lb (208 g).
The PXIe-6672 has been declared Mature by National Instruments, but the Synchronization Module will remain available for purchase and repairs in perpetuity with Apex Waves.
