I’ve pieced together a 24-bit analog to digital conversion circuit and I’m using the AD7730 ADC and an ECS-49-18-5PXEN for the master clock inputs, however the crystal is not behaving as expected. I’ve attached a schematic with notes highlighting my issue. I’m getting the 4.9152MHz signal on the MCLKOUT pin, yet nothing on the MCLKIN pin. Does anyone see anything obvious that I'm doing incorrectly?
Thanks for your time
I have forwarded AD7730 sample code to your private mail. If you need anything else, feel free to let us know.
JohnnyG, Hello. I have some problem with initialization of ad7730. As i understand it may be problem with rezonator connection probably. But could you send an sample to mail or post it here.
