6.1.1. Formatted Odd and Even Interleaved output Although the CV-A20CL CMOS sensor operates at 148.5MHz, the output pixel rate is a half of that, 74.25MHz due to using the Formatted Odd and Even Interleaved output. Odd pixels of lines and even pixels of lines are output respectively as shown the below. - Page 10 CV-A20 CL / CV-A80 CL Fig.10. Transition of each part of Snap-shot trigger operation Ext. Trig FVAL Strobe out Exposure on Sensor Exposure Line #1 Exposure Line #1125 Data Output 1125 Sensor Readout Stop Period Note: The above drawing shows the case of "Strobe Delay Time = 0". Important Note: The CMOS sensor does not have a mechanism that allows pixels to be reset at one time, and is therefore accumulating and reading out continuously.

Page 11: Window Scan
The CV-A20CL/CV-A80CL permits "Windowing" in the vertical direction. This reduces the number of lines being read out, thus increasing the frame rate. For the CV-A20CL the increment is 1 line and for the CV-A80CL the increment is 2 lines. Depending on the number of lines selected the frame rate can be varied from 60 fps for full line read out to 1125 fps. -
Page 12: Frame Rate For Window Scan Mode
CV-A20 CL / CV-A80 CL 6.1.4. Frame rate for Window Scan Mode The frame rate is calculated as follows: Frame frequency = 1L [67,500] divided by (Blanking Period [45] + windowing scan period [lines]) For instance, in the case that the vertical window is set at 540 lines the frame frequency is 67,500 ÷... -
