I would like to use the ISERDESE3 with DATA_WIDTH=4 and with DQS data strobe from a NAND Flash Memory device.
In spec, page 197, figure 2-26 (attached):
The figure seems to imply that clock (CLKOUT0) is a continuous clock.
I don't see clearly in the spec any reference to the use of a DQS strobe as input clock to the ISERDESE3.
also, in fig 2-13 page 165 (attached), the data is sampled on the falling edge of the clock, do I need to invert DQS?
thank you for any help
Do you want to get more information using data strobe? You can have a look at IP- High speed select IO in pg188: https://www.xilinx.com/support/documentation/ip_documentation/high_speed_selectio_wiz/v3_5/pg188-high-speed-selectio-wiz.pdf
