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 ).
