I guess ST is still making mediocre controllers. After an adventure with the STR700 series I switched to NXP and never looked back at ST. Appearantly a good choice :-)

35MHz clock at the peripheral -- the ST chip he's looking at is rated for 70 or 72MHz or some such.

AFAIK most ST devices can't run from flash at their rated clock speeds. NXP's can and some go up to 120MHz (180MHz is on its way)!

th
rSTM32F4 has a flash accelerator similar to NXP and run at full speed
168MHzthe stm32f107 looks to have 2x I2S that can run at pclk/2 the ad1933 can run dual line so I think it should be possible

Yes, good point. And part of my point to the OP is that once he solves his ADC throughput problem, is he going to be able to generate the data?
Depending on his application, a teeny bit of code running out of RAM in the '107 may be enough. Or, the app may self-destruct on a ton of code running at 120MHz on your NXP.
