Hi,
I'm trying to understand the EMC problems that can arise from digital circuits.
I've one board where there is an SRAM part number IS61WV25616BLL-10BLI operating at 3.3V (datasheet attached)
It is specified as 8ns speed (read cycle time) and 1V/ns rise time.
Can we correlate this information to the potential EMC frequencies that can arise from this circuit?or How to estimate the potential problematic frequencies with this information..
I ve read that as the rise time decreases the band width of the system increases and the relation tr=0.35/f
Here should i calculate using a continuous read cycle of 8ns or just use the rise time (since operating voltage is 3.3V im assuming it like 3.3ns , as 1V/ns is mentioned) ?
Thanks for any help.
