    The NI-5782 clock source controls the sample rate and other timing functions on the device. The following table contains information about the possible NI-5782 clock sources.

    Table 1. NI-5782 Clock Sources
    Clock Frequency Source Options
    Internal Clock PLL Off 500 MHz The internal voltage-controlled oscillator (VCO) acts as a free-running clock.
    Internal Clock PLL On (IoModSyncClock) 500 MHz The internal VCO locks to PXI_CLK10 through IoModSyncClock, which is available only through the backplane of PXIe-796xR devices.
    Internal Clock PLL On (CLK IN) 500 MHz The internal VCO locks to an external Reference Clock (10 MHz). Connect the external Reference Clock through the CLK IN front panel connector.
    External Clock (CLK IN) 250 MHz to 1 GHz Connect an external Sample Clock through the CLK IN front panel connector.
    External Clock (IoModSyncClock) 250 MHz to 1 GHz Connect an external Sample Clock through the IoModSyncClock, which is available through the backplane of PXI-796xR and PXIe-797xR devices.
