Before using the Blackfin A-V EZ-Extender, follow the procedure in “A-V 
EZ-Extender Setup” on page 1-2.
Figure 2-2 shows the jumper header locations. The jumper headers are 
divided to show each jumpers placement and rotation. The jumpers are 
described by the pins of the header on which the jumpers can be placed.  Figure 2-2. Jumper Locations

2-8 Blackfin A-V EZ-Extender ManualFor example, 
JP3.4/6/8 refers to a single jumper that can be placed across 
pins
4 and6 (or pins6 and8) of JP3. The dark pin indicates pin1 of each 
header. 
Video Test Loopback Jumpers (JP1.1/2, JP1.3/4, 
JP1.5/6)
For test purposes only, the video test jumpers loop-back the video 
encoder’s output signals to the video decoder’s input signals. By default, 
none of the video test loopback jumpers are installed.

PDWN Connect Jumper (JP3.9/10)
Depending on the application, the PDWN pin of the OmniVision and 
Kodak cameras can be left floating or controlled by a flag pin 
(seeTable 2-4).
Decoder HSYNC Disconnect Jumper (JP3.11/12)
To connect the horizontal sync signal of the video decoder to the PPI0 
frame sync signal of the processor, install jumper 
JP3.11/12; otherwise, 
the decoder’s horizontal sync is disconnected.

Encoder HREF Connect Jumper (JP3.15/16)
To connect the horizontal sync signal of the video encoder to the PPI0 
frame sync signal of the processor, install jumper 
JP3.15/16; otherwise, 
the encoder’s horizontal reference is disconnected. 
Encoder VSYNC Connect Jumper (JP3.17/18)
To connect the vertical sync signal of the video encoder to the PPI0 frame 
sync signal of the processor, install jumper 
JP3.17/18; otherwise, the

PPI Clock Setup Jumpers (JP4.1/2, JP4.3/4, JP4.5/6, 
JP4.7/8)
The PPI_CLK signals of PPI0 and PPI1 are configured by the clock setup 
jumpers (see Table 2-5). For more information, refer to Figure 2-1 on 
page 2-4. 
PPI0 D8–15 Enable Jumper (JP5.1/2)
The JP5.1/2 jumper, when is not installed, disables the upper eight bits of 
the 
PPI0 data bus. This allows the signals connected to the upper eight bits 
of the PPI data bus of the...

VID_OUT Data Bus Control Jumpers (JP5.3/4, 
JP5.5/6)
The JP5.3/4 and JP5.5/6 jumpers are used together to set up the direc-
tion of and enable/disable the 
VID_OUT data bus drivers. Table 2-6 shows 
different combinations of 
JP5.3/4 and JP5.5/6.
PPI0_SYNC1 Direction Setup Jumper (JP6.1/3/5)
The direction of the PPI0_SYNC1 signal can be either fixed or programmed, 
depending on the state of a general-purpose flag. Table 2-7 shows how to 
set up the 
PPI0_SYNC1...

PPI0_SYNC2 Direction Setup Jumper (JP6.2/4/6)
The direction of the PPI0_SYNC2 signal can be either fixed or programmed, 
depending on the state of a general-purpose flag. Table 2-8 shows how to 
set the 
PPI0_SYNC2 direction.
I2S Enable Jumper (JP7.1/2)
When JP7.1/2 is installed, the SPORT signals are routed for I2S SPORT 
communication protocol mode. To accomplish this, the receive and trans-
mit clocks of the processor are driven...

VID_OUT Bus SYNC Source Select Jumpers 
(JP8.1/3/5, JP8.2/4/6)
The source of the PPI frame sync signals depends on the PPI port driving 
the 
VID_OUT bus. When using PPI0, place the jumpers at JP8.1/3 and 
JP8.2/4. When using PPI1, place the jumpers at JP8.3/5 and JP8.4/6. 
VID_OUT Bus SYNC Enable Jumper (JP8.7/8)
To enable the VID_OUT frame sync signals, install JP8.7/8.

PPI0_D Direction Setup Jumper (JP9.2/4/6)
The direction of the PPI0_D[15:0] signals can be a fixed direction or can 
be programmed, depending on the state of a general-purpose flag. 
Table 2-10 shows how to set up the 
PPI0_D[15:0] direction.
Audio Loopback Jumpers (JP10.1/2, JP10.3/4)
