AD9695 Eval Board Trace Impedance Matching

Also, where is the C550 capacitor located? I couldn't find it anywhere on the board.

Does anybody have an idea?

Hi Hyomin Ahn,

Moved this question to High-Speed ADCs forum. 

I answered the impedance matching here: EEPROM Board ID for AD9695 - Q&A - High-Speed ADCs - EngineerZone (analog.com)

For the C550, it is located here:

Thank you so much though Peevee!

Peevee, I was also wondering- what is this X with a box at the connection here? Are 1V8_SPIVDD and AVDD_SPI_REG the same net? I noticed that in the schematics sheet that one side of P312 is connected to AVDD_SPI_REG. But in the board file, the same side of P312 shows up as 1V8_SPIVDD.

Yes you are correct, 1V8_SPIVDD and AVDD_SPI_REG are the same. This is for easier reading on the schematic.

The tool doesn't allow a single net to have multiple names. In order to make naming a net with a different signal possible, this "TIE" symbol is used.

I hope I was able to explain it well.

Thank you very much!! Yes you are always able to explain things very clearly!!
