I would like to use an AD9910 with a simple crystal as clock source. I saw in the datasheet that the crystal frequency recommended is 25MHz. But is it possible to use a 10MHz crystal or an 8MHz?
Thanks in advance
The datasheet doesn't specify any minimum or maximum value of the clock, but just the typical value. So it follows that the 25 MHz clock frequency is a required value. The circuitry within the device is tuned to a specific crystal clock frequency so it is necessary to follow that value. The value of a clock source from a signal generator can vary at a wide frequency range but not with the crystal clock.
The REF CLK frequency operating range in XTAL mode should be 20MHz to 30MHz.
