SPI interface with AD9230 - ADG3308

We have 4 AD930 and the SPI controller is in an FPGA which output level are 3V3. We have used an ADG3308 to translate their level to 1V8. RESET, SDIO and SCLK are the same pin from the FPGA to the 4 ADCs. It seems that ADG3308 doesn't give enough current to carry the signal to the 4 adcs.. Can you please confirm me I am right? If yes, is there a compatible part to ADG3308? Thanks!
