What "stripes" mean in AD9266

I'm using a AD9266 and i have overshoots on the exits of the can. So i would
like to change the output driver. I think i have to modify the register 0x15
with the SPI link, but i don't understand what "stripes" means. To lower the
driver, have i to put one stripes or four stripes ?

 

It refers to the quantity of transistor stacks or "stripes" that are invoked
for a given drive strength setting. To lower the drive strength, you would
reduce the number of "stripes". One "stripe" has lower drive strength than four
"stripes".

Also, some systems also use series slew damping resistors (~100 Ohms) between
the ADC outputs and FPGA/ASIC receiver inputs to further quiet switching noise.
You may not need this, though.
