I am working with the AD9914 and its evaluation board. The SYNCCLK signal I get is the typical triangular shaped waveform that others have mentioned on this site. However, I need to convert it to a square wave between 0V and 3.3V to synchronize the AD9914 with an FPGA. I'd appreciate any recommendations for the best way to do this. Does AD make a clock buffer that could do the job?
