AD6688 SPI

Question

Hi, 
 
 We are using three AD6688 ADCS's in our design. 
 Can we use same SPI lines for all three ADCs providing different chip select for each ADC. 
 Currently we are using different SPI for all three. 
 Do we need to take any special care if we use same SPI for all three? 
 
 Note: SPI control is from Intel Stratix 10 FPGA 
 
 Thanks & regards, 
 Aravind D

 you need to make sure your SCLK and SDIO pins have enough drive strength to support three SPI buses in parallel.)
