MISO Disconnect Jumper (P7)
The SO signal of the SPI connector ( J1 ) is driven by a buffer to the proces-
sor’s MISO signal, as illustrated in Figure 2-1 on page 2-2 . When the SPI
connector is not in use, remove the jumper to prevent any interfering with
other devices on the SPI bus.
SMA Connector Clock Disconnect Jumper (P10)
The SMA connector ( J5 ) provides the ability to input a clock from a sig-
nal generator or other clock source. This signal is first put though a buffer,
as illustrated in Figure 2-1 on page 2-2 . When the SMA connector is not
in use, remove the jumper to prevent any interfering with other devices on
the net.
PPI Data Routing Jumper (P36)
The flexibility of the EZ-Extender used with the Blackfin processor’s sin-
gle and double PPI requires the PPI data signals to be routed accordingly.
Figure 2-2 and Figure 2-3 show the data flow when P36 is installed and
when it is not installed.
When connecting to the OV6630AA evaluation module, ensure
that the P36 jumper is not installed. The signals attached to PPI1
are used as input by the camera.
