<azonenberg> Anybody have experience using the Xilinx 7 series OSERDESE2 in width expansion mode (cascading master and slave sides) with 10 bit width?
<azonenberg> UG475 says you need to feed the high two data bits into D3/D4 (per figure 3-15)
<azonenberg> after several hours of tearing my hair out I appear to be getting good results when I feed to D7/D8

<lain> that would be a fun typo >.>
<azonenberg> lain: thats the thing
<azonenberg> i dont know if it's a typo. i've found other code online using 3/4
<azonenberg> which confuses the hell out of me
<lain> oh weird
<azonenberg> for the moment i have my signals fed to 3/4 and 7/8 so one of the two will work
<azonenberg> but i have no clue why it's doing this
