LMH1297: SPI or I2C Interface with LMH1297?

Part Number: LMH1297
Other Parts Discussed in Thread: SIGCONARCHITECT

Hello, wanted to ask the Community members who have some experience with the LMH1297 which interface is better SPI or I2C? If you have any comments please share them with me. I'm doing a design using 4 LMH1297 devices and trying to decide which interface I should use. I'm interfacing with an FPGA so I have lots of pins that I could use as an SPI channels.

Thank you very much,

Joe

Hi Joe,

I prefer I2C interface.I2C interface allows us to use SigconArchitect GUI for quick debugging. This GUI allows us to capture eye diagram quickly without any need for software development on FPGA or ASIC.
