Dear All,
I have a PCIe-6363 and a PCIe-6537 card installed on the same computer and connected by an RTSI cable. The PCIe-6537 receives sample clock from PCIe-6363 through RTSI . I generate a counter output task on PCIe-6363, and identify the relevant PFI as the sample clock source for a digital output task on PCIe-6537. With this configuration, I can achieve maximum 25 MHz sample rate (low and high times in a counter task can be minimum 2 periods of the timebase).
Is it possible to get a higher clock from PCIe-6363 for use as sample clock on another card?
Thank you very much in advance for your comments.
Aside: In my application, the PCIe-6363 also provides a reference clock to PLL of another card that needs to be operated in synchronization with PCIe-6537. I attempted to generate the reference clock also from PCIe-6537, but it didn't work since the ref. clock should always be on (not only when the DO task is running). So I can't use PCIe-6537's internal sample clock.
