LMH0397: SPI Transaction with standard Xlinx XSPI

Part Number: LMH0397
Other Parts Discussed in Thread: SIGCONARCHITECT

Hi support team,

we would like to use the standard SPI interface from Xilinx  (XSPI) to communicate with the LMH0397. But the XSPI interface is limited to bytewise transaction, which means that only multiple of 8bit can be transmitted.

On a trial we built up a SPI Read transaction with 3 Bytes instead of 17 bit like specified in the data sheet and set the leading bits to '0'. Then we read out the device ID from the Share Register Page

At a first glance it looks like that we received the correct data, but other tests failed.

Is it possible at all to communicate with the LMH0397 without complying to the 17bit transaction width?

Best regards and take care

Martin
