Hardware and EVM Setup for Testing ADS5296
The ADS5296 EVM has eight SMAs vertically mounted on the topside of the board corresponding to eight
analog input channels labeled CHx_XFMR, where x = 1 to 8, as shown in colored boxes of
Channels 5, 6, 7, and 8, highlighted by the yellow box, are configured for octal non-interleaving mode and
are driven through the back-to-back transformers on the top side of the board, while channels 1, 2, 3, and
4, highlighted by the blue box, are disconnected from the DUT. This is evident by the installed 0-ohm
jumper resistors at R210, R399, R209, R386, R208, R394, R207, and R304 and by the uninstalled 0-ohm
resistor jumpers at R378, R379, R155, R154, R166, R165, R168, and R167, respectively.
