LVDS generation - repeat mode clock rate

[SayMaster]

Hi Guys,

 

I am trying to get a PXI 6562 up and running.

 

I want to save a pre-generated pattern to the card and just repeat it continuously.

Everything seems fine till I go over a clock rate of 25Mhz, then I get an error 0xBFFA4C3 which tells me that the card cant keep up with this sample rate.

 

Is there a tweak I can reach up to 100Mhz? Is there any description about this behavior? At least I cant find anything 😕

 

thanks in advance!

okay, small finding:
 

if my Data is 40 bytes the card can handle up to 200Mhz in repeat mode

if my data is 16 bytes it can repeat mit 100Mhz..

 

still missing an information about this behavior...

It's in the error message - Waveform might be too small. Probably there is an overhead required for transitioning to the next waveform.
