Hello,
The IPL I am working off of calls out FIFO P/N: 72V205L15PFGI. I accidentally ordered P/N: 72V205L10PFG Cross referencing the data sheets I don’t believe there would be an issue, but was hoping one of you could confirm. All that stands out is the one I purchased has the shorter access time and higher frequency data rate.
Thanks in advance,
Bryan
Hello manchester49123,
Great question! The differences between the 72V205L10PFG and the 72V205L15PFGI are shown below in the ordering information part number breakdown. The clock cycle time for the “10” version is lower, meaning that it has a higher frequency and operates faster. The “15” calls out a higher clock speed, meaning it operates at a slower frequency. The “I” shows that it has a wider temperature tolerance for more rugged environments.
This ordering information breakdown can be found on page 25 of the datasheet HERE.

Thanks Klint! So lower the clock cycle time (Tclk) is better, because that would mean higher the frequency and better processing, correct? So 72V205L10 PFG would be superior in performance?
My apologies, I misread your original post as to what the original part you were looking for was. Yes, you are correct in that the 10 nanosecond clock speed translates to a higher frequency, meaning it operates faster. I have edited my previous post to make that a bit more clear. It is superior in performance if you are able to make use of that speed, however it may consume more energy if you’re running it at the higher speeds as well.

Klint
