I am now using the LMK61E2. I wrote an FPGA-based IIC configuration code snippet to change the default frequency to 250 MHz (the code was verified and can work correctly).
Here is my situation: I am certain that I encounter the problem of using wrong IIC address of LMK61E2. In my hardware circuit, the ADD pin is connect to VCC, so I use the 0xB2 as the IIC address as implied in the datasheet. But the LMK61E2 chip don't acknowledge correctly by giving the ACK bit high level.
I checked my specific chip number is LMK61E2 66ZNN73, I wonder if the number determines the specific IIC address of my chip. What IIC address should I use?
Thank you very much.
