    • 1 CLKIN fundamental frequency can be any multiple of 1 MHz within the range specified when the PLL is engaged and PXI_CLK10 is locking to it. The frequency must be 10 MHz when replacing PXI_CLK10 without the PLL.
    • 2 Stresses beyond those listed can cause permanent damage to the device. Exposure to absolute maximum rated conditions for extended periods of time can affect device reliability. Functional operation of the device outside the conditions indicated in the operational parts of the specification is not implied.
    • 3 This is a requirement of the PXI specification.
    • 4 The lower limit is load dependent because of the AC coupling. This limit is less than 1 MHz for high-impedance loads.
    • 5 The duty cycle specification covers both DDS range and TCXO.
    • 6 Stresses beyond those listed can cause permanent damage to the device. Exposure to absolute maximum rated conditions for extended periods of time can affect device reliability. Functional operation of the device outside the conditions indicated in the operational parts of the specifications is not implied.
    • 7 Relative to PXI_CLK10 at the backplane connector. When PLL is used to route CLKIN to PXI_CLK10_IN, CLKIN and PXI_CLK10 are phase locked with ±1 ns max phase difference.
    • 8 Relative to PXI_CLK10 at the backplane connector. When PLL is used to route CLKIN to PXI_CLK10_IN, CLKIN and PXI_CLK10 are phase locked with ±1 ns max phase difference.
    • 9 Stresses beyond those listed can cause permanent damage to the device. Exposure to absolute maximum rated conditions for extended periods of time can affect device reliability. Functional operation of the device outside the conditions indicated in the operational parts of the specifications is not implied.
    • 10 Relative to PXI_CLK10 at backplane connector.
    • 11 This specification applies to all synchronous routes to the PXI_Star lines, as well as asynchronous routes from the PFI inputs to the PXI_Star lines.
    • 12 Includes stability of TCXO and supporting circuitry.
    • 13 Includes temperature stability of TCXO and supporting circuitry.
    • 14 The DDS frequency inherits the relative frequency of PXI_CLK10. For example, if you route the TCXO to PXI_CLK10, the DDS output inherits the same relative frequency accuracy as the TCXO output.
    • 15 Cable length measurements were made with an RG 58 cable. Maximum cable length performance will vary depending on the cable type used.
    • 16 Maximum cable length with a direct cable connection. Loss from a signal splitter would reduce maximum cable length.
    • 17 Maximum cable length with a direct cable connection. Loss from a signal splitter would reduce maximum cable length.
