To interface AD9234-1000EVM ADC cards for  12.5Gbps JESD204B lane data rates

Does AD9234-1000EVM support 1.25GSPS/12.5Gbps lane rates i.e. Max switching characteristics shown in data sheet at Nominal operating conditions ?

I have these  ADC cards, Are these cards reliable for 12.5Gbps JESD204B data rates analysis ?

    Hi,

    I am not sure what your end goal here is. The AD9234 is rated for a max clock rate of 1GSPS. Please see the AD9234 datasheet for more information. If you want 12.5Gbps line rate, ie, if that is ALL you are looking for, you can clock the AD9234 at 1.25GSPS and get data output at 12.5Gbps. However, dont expect the ADC performance to hold up to datasheet specs.

    For 1.25GSPS operation, please use AD9680-1250EBZ. This chip outputs data at 12.5Gbps. The AD9691 is a eight lane version of the same chip. So you have the flexibility to either use eight lanes at 6.25Gbps/lane or four lanes at 12.5Gbps.
