What is the Accuracy of the 20Mhz Clock on the DIO-32HS (NI 653x) Cards?Hardware: Digital I/O (DIO)>>High-Speed>>AT-DIO-32HS
Problem: What is the accuracy of the 20 MHz timing on the 653x cards? Solution: The accuracy of the input or output timing is equal to the accuracy of the oscillator that drives the timing circuitry. These boards have a 20 MHz oscillator made by Seiko/Epson, p/n SG-615PC. The data sheet is attached below. On the data sheet, the accuracy is listed as +/- 100 ppm. This translates to +/- 0.01% ((100 / 1000000) * 100). Related Links: Data Acquisition Support Homepage Attachments:
