Video Data Output For The A501K/Kc - Basler A500k User Manual

This diagram assumes that the area of interest feature is not being used. With the area of interest feature enabled,
the number of pixels transferred could be smaller.

2.5.6 Video Data Output for the A501k/kc

cameras output the video data in a 2 * 8 Bit data stream.

A501
The pixel clock is used to time data sampling and transmission. As shown in Figures
10, the camera samples and transmits data on each rising edge of the pixel clock.
The image has a maximum size of 1280*1024 pixels that are transmitted with a Pixel Clock
frequency of 50MHz over the Channel Link transmitter/receiver pair X. With each clock cycle two
pixels at a depth of 8 Bits are transmitted in parallel. Therefore one line takes a maximum of 640
clock cycles to become transmitted. For more details about sensor timing, please refer to the
Micron MV13 data sheet (www.micron.com).
Due to the internal sensor design, the Area of Interest feature is restricted in horizontal directions
to values that are multiples of ten. For details please read the register description of the AOI
Starting Column and the AOI Width register. Image is transmitted line by line from top left to
bottom right. Frame Valid (FVAL) and Line Valid (LVAL) mark the beginning and duration of frame
and line.
The line valid bit indicates that a valid line is being transmitted. Pixel data is valid when the line
valid bit is high.
