Hello I am using 16 AD5933’s with a clock frequency of 10kHz. I want to know whether i can use single clock oscillator to supply for 16 chips (OR) 16 clock oscillators to supply to 16 AD5933 chips.

10kHz ? is it not too low?
Be careful about clock jitter.
Yes, you can use the same clock, assuming your clock can drive few inputs.

Sorry Miguel, Instead of writing 100kHz i wrote 10kHz.
What if it is 100kHz.
I’m planning to use a clock Buffer LMK00101 from Texas Instruments and use a 100kHz as input to that Buffer and then supply to 10 AD5933’s.
Clock jitter is too less according to the Data sheet of LMK00101. Is it possible to use that?
According to the application note-AN483, we are clock dividing 1MHz to 100kHz using multiple D-Latch, is there any clock jitter from D-latch. If so is there any need to go high precision D-Latch.
Yes, you can use 100kHz mclk and the TI part.
say that, the TI part is for clock generation using crystals... Why you are not buying a crystal of 100kHz directly?

There are no crystal oscillator of 100kHz. We are also to generate clock using LT6906 from Linear Technologies.
Is it okay to use that??
Or is there any clock oscillator of 100kHz of high precision.

LTC jitter is huge.

The crystal must be connected to the TI part, rather than use the LTC part to generate a clock.

You might be knowing how to supply clock to AD5933 MCLK pin. But with the above crystal oscillator (http://ie.farnell.com/citizen-finetech-miyota/cfv206-100-000kazf-ub/cristal-100khz-cyl/dp/1457087) how can we connect the crystal to the MCLK pin.
