Resistors R8, R7, R11, and R12 are all 0 ohm resistors. The input terminals (IN+ and IN-) have corresponding sense lines so that the inputs to the device can be terminated on the lines with 50 ohms to an oscilloscope. This allows the input signals to be observed with minimal loading and distortion.

The TLV3605EVM has an optional resistor pad between the device inputs meant for a 100 Ω resistor. This resistor is only needed if applying an unterminated LVDS signal to the board, otherwise it can be left uninstalled.
