1.2.2 Output signals
Set the output signals from the power/IO connector.
The following six output signals are selectable with the software or communication.
A) FrameTriggerWait
The user can check the camera conditions, which are the camera expose and the image output
processing by the trigger signal with this FrameTriggerWait signal.
a) High status (Voltage of the “IO VCC IN”): No processing by the trigger signal
The camera accepts the trigger signal
b) Low status (0V): The camera is expose and the image output processing by
the trigger signal
The camera default setting is the input trigger signal is INVALID while low status for this signal.
When the exposure starts while the image output by next trigger signal, please change the camera setting
(Device code: 00H, Command: 13H) to accept the trigger signal while the image output.
The noise appears on the image when start exposure while the image output. In this case, please change
the “H reset”for the exposure start mode (Device code: 00H, Command: 12H) to change the exposure
start point to next HD timing.

3 User configurable FPGA (XILINX)
The customer would program the provided FPGA (XILINX) with its own proprietary code and the customer would
also have complete control over the “Memory”utilization.
Sentech checks the camera for proper operation by “Disabling”around the customer’s code and memory control.

3.2.2 Explanations of data flows
3.2.2.1 Image data
3.2.2.1.1 Image data flow
1) The analog image signal created by the CCD is processed through CDS (Correlated Double Sampling)
section and then is converted into digital data by the A/D converter.
2) This data is sent to "Sentech FPGA" for further processing.
3) Once the data is sent into "Sentech FPGA", the image data can be routed to "User Configurable FPGA".
Three different extraction points are provided in "Sentech FPGA" for this purpose. Please see
Section-3.2.2.1.2-2) for more details.
4) This data is further processed by the program you create in "User Configurable FPGA".
5) Now, the data should be returned to "Sentech FPGA". In this process, again, three different points are
provided in "Sentech FPGA" to return the data to. Please see Section-3.2.2.1.1. 3) for more details.
6) The data is sent to "GigE I/F (Interface)" and sent out through the Ethernet connector.

3.2.2.1.2 Image data extraction and insertion
The image data generated by the CCD is converted into 12-bit digital data as the section 3.2.2.1.1
explained. Then this data is extracted into the user FPGA, processed and inserted back to Sentech
FPGA.

2) Data extraction from Sentech FGPA
The 12-bit image data is extracted from Sentech FPGA as DIN11-0 into the user FPGA from any points
listed below. These points A, B and C are indicated in fig.2 (Image data flow block diagram).
A) For the color camera
A. CCD raw data
B. Data after the white balance processing
C. Data after the white balance and the gamma processing
B) For the color camera
A or B. CCD raw data
C. Data after the gamma processing
3) Data extraction from user configurable FGPA
After processing the 12-bit image data in the user FPGA, the data is inserted back to the Sentech FPGA
as DOUT11-0 at any points listed below. These points A, B and C are, again, indicated in fig.2 (Image
data flow block diagram).
A) For the color camera:
A. Before the white balance, the gamma and color interpolation processing
B. Before the gamma and the color interpolation processing
C. Before the color interpolation processing
B) For the monochrome camera
A or B Before the gamma processing
C Before the output from the camera (No processing)
4) Data assignment list
Please see section 3.3 for the data assignment.
It is not necessary to consider these data pin assignments if use the pin assignment and the timing
constraints file (Power_plus_000.ucf).

5) Image data switching method
As explained in the section 3.2.2.1.2, there are three points to extract out the image data from the
Sentech FPGA and the image process at Sentech FPGA after the image data send back from the user
configurable FPGA. There are two different methods to achieve this switching.
A) By using Sentech GUI “StCamGigEWare_OpDemo”
