We ordered some AD9219 in the 65MSPS variant.
The labels on the devices read "ABCPZ-65".
But the speed grade register has the value "0x01", which according to the manual means 40MSPS.
So how can we find out definitely which version we have?
I believe you have the 65MSPS version. According to the datasheet, the first 4-bit nibble contains the speed grade information. As such, Register 0x02 = 0x01 indicates the 65MSPS device.
Thank you for considering the AD9219.
This certainly sounds strange. I will look into it to see if there is a mix up somewhere, and get back to you as soon as I can. Sorry for the inconvenience.
The LSB is indeed irrelevant for the speed grade information.
