RS-232 Ports, VGA Port, and PS/2 Port
IC2 is the Maxim LVTTL to RS-232 level converter. One of the serial channels connects to a
female DB9 DCE connector (J9) and the other connects to a male DB9 DTE connector (J10).
See
Chapter 7, “RS-232 Serial Ports,”
for additional information.
Connector J14 is a PS/2-style mouse/keyboard connector, powered from 5 volts. See
Chapter 8, “PS/2 Mouse/Keyboard Port,”
for additional information.
Connector J15 is a VGA connector, suitable for driving most VGA-compatible monitors
and flat-screen displays. See
Chapter 6, “VGA Display Port,”
for additional information.
Header J12 provides programming support for the SPI serial Flash. Jumper J11 controls
how the SPI serial Flash is enabled in the application. See
Chapter 12, “SPI Serial Flash,”
for additional information.
The SMA connector allows an external clock source to drive one of the FPGA’s global clock
inputs. Alternatively, the FPGA can provide a high-performance clock to another board via
the SMA connector. See
for additional information.
