The SMA connector is AC-terminated through a 0.1uF 0402 capacitor. Between J1 and the
capacitor is a 0-ohm 0402 resistor. Between the capacitor and FPGA pin K14 are two 49.9-
ohm 0402 resistors, one pulling high to the Bank 0 I/O voltage (VCCO_0) and the other
pulling low to GND. The user may alter this configuration to suit his requirements.
