I am using this QSPI Flash Memory IC
I'm operating the QSPI clock at 48MHz. I am probing the Clock and Data signals in my scope.
On Table 54 which is on Page 128, we have Rise time and fall time specifications. But the specification is given in terms of slew rate instead of seconds. How to convert it into seconds format.
I tried doing the below approach :
Considering figure 12.4.1 in page 129, rise time and fall time are given with respect to Vil max and Vih min which is 0.99V and 2.31V respectively.
So, 2.31V-0.99V = 1.32V.
But rise time is given as 0.1V/ns.
So, if 0.1V is for 1 ns, then 1.32V should have a rise time of 13.2ns?
I think this is wrong approach. Can someone help me with this on how to find the rise time in terms of seconds instead of slew rate?
