Other Parts Discussed in Thread: DAC8814
Hi,
I would like to use the DAC8803 in a new design and I need to be able to clock it with at least 40MHz from an FPGA.
The datasheet's title page's Feature lists says the DAC8803 is compatible with a 50MHz SPI bus. But the interface timing specifications say the minimum Clock width high (and low) is 25ns, which would amount to a maximum clock frequency of 20MHz. (Please correct me if I am wrong on this)
The very similar DAC8814 can be clocked at 50MHz, and the document SLAA316 states the DAC8803 is clocked at 30MHz, so I am inclined to think that 50MHz is indeed possible, but would appreciate it if this can be confirmed.
Thank you!
