21. SMA Interface

The Z19 development board has three pairs of differential lines, which are drawn
through six SMA interfaces, one pair is clock signal and the other two pairs are data
signals. The differential signal is connected to the IO of the BANK68 (level standard 1.8V
or 1.2V and can be adjusted via hop cap). Figure 21-1 shows the design of SMA
interface.
