2.5 Output Signals

Data is output from the A500
in Section 2.5.1, the Line Valid signal in Section 2.5.2, the Frame Valid signal in section 2.5.3, and
the video data in Section 2.5.4. How the Video Data is output is described in sections
2.5.6. Section

modified to be able to transmit 80 bits of data in parallel. Framegrabbers are available for the
Basler-specific bit assignment.

2.5.1 Pixel Clock

As shown in Table 2-7 for the A501
to the XClk, and for the A504
Link transmitter, as defined in the Camera Link standard. The pixel clock is used to time the
sampling and transmission of pixel data. The Channel Link transmitter(s) used in A500
require pixel data to be sampled and transmitted on the rising edge of the clock.
The frequency of the pixel clock is 67.58 MHz for the A504
each Pixel Clock signal, 10 pixels for the A504
a depth of 8 Bits.

2.5.2 Line Valid Bit

As shown in Figures
Pixel data is only valid when this bit is high. 640 ( A504
required to transmit one full line. As in the camera link standard, line valid is connected to Channel
Link transmitter/receiver pair X, and in the A504
In contrast to the camera link standard, line valid is assigned to different pins in the A504

2.5.3 Frame Valid Bit

As shown in Figures
transmitted. One frame can contain 2 to 1024 Line Valid signals. Line valid and pixel data is only
valid when this bit is high. In contrast to the camera link standard, frame valid is only connected
to Camera Link X in the A504

2.5.4 Video Data

Table 2-6 and Figure 2-5 show the assignment of pixel data bits to the input pins on the Channel
Link transmitters X, Y, and Z of the Camera Link in the camera and the corresponding output pins
on the Channel Link receivers X, Y, and Z in the frame grabber for the A504
the assignment for the frame valid bit and the line valid bit.These signals and the data transmitted
via the three Channel Link transmitter/receiver pairs is not assigned according to the Camera Link
standard. The Basler-specific connection is described in Table 2-6. Note that framegrabbers are
available for the Basler-specific pin assignment.
Table 2-7 and Figure 2-6 show the assignment of pixel data bits to the input pins on the Channel
Link transmitter X of the Camera Link in the camera and the corresponding output pins on the
Channel Link receiver X in the frame grabber for the A501
the frame valid bit and the line valid bit.
