yes. they are fixed.
I have a design that uses dual AD9645s. Currently they are both clocked with a 1x sample rate clock, so they stay synchronized.
We would like to test with a higher speed reference clock, but I am concerned that once we use the internal clock divider the…
Thanks for considering the AD9645. The AD9645 works in a default mode without SPI commands. If you keep CSB high the SPI port is disabled.
If you use AD9645 in non-SPI mode, please be sure to comply with the instructions in the POWER AND GROUND…
Thanks for your interest in ADI ADCs. Is a dual (2 channel) device sufficient? If so, please review the AD9645 ( www.analog.com/.../ad9645.html ).
Thank you for working with the AD9645.
Your understanding for Point #1 is correct. The CVT-ADC-FMC-INTPZB is not compatible as-is with the AD9645 evaluation board. Fortunately there is a relatively easy fix, if you do not mind doing…
