PCI-6533 DIO

[jimhar66]

Hi,
 
We were hoping to use a PCI-6533 for emulating a SPI slave device at 13Mbps using pattern mode acq with external clock tied to REQ line.
 
However, I am a little confused on device specs which indicates 2MHz rate for DIO card.  Is this the max strobe (clock) that can be applied to 6533? 
 
Our requirements do not require continuous high-rate data transfers to host.  
 
Thank you,

Hi Jim,
 
Take a look at the following website, which goes into much more detail about the rates you can achieve (scroll down to the bottom to see the benchmarks):
