SMA External Clock Connector

An external clock input (Figure 2–30) is available to drive different clock

frequencies into the FPGA. The input is a standard SMA coaxial cable

connector (J5). Refer to “Clock Circuit” on page 2–13 for a description of

the circuitry attached to this connector.

Power Supply Connector

The Cyclone II FPGA Starter board receives its power from either the USB

port directly or the included 7.5V power adapter, which plugs into power

connector J8 (Figure 2–31).
