Hi,
The SPI interface of LMH6518 has only one line for data (SDIO) while a standard SPI interface has two data lines (MOSI & MISO). How to connect a standard SPI interface with LMH6518?

Hello Hooman,
Thanks for the prompt reply. I was planning just the reverse topology, i.e. SDIO connected directly to data_out of master and through a Hi-Z buffer to data_in of master. I planned this way because I will mainly write to LMH6518 and I will only read back if the o/p of the amplifier is something other than expected. Do you find any problem in this configuration?

Hello Supratim,
Your LMH6518 SPI connection method would work just as well. As long as SDIO is connected as either Input or Output (but not both), by tri-stating the unwanted line at the appropriate time, you are OK.
