5.3.1. Trigger input

The trigger inputs on pin #10 12 pin Hirose connector is AC coupled. To allow a long pulse width, the input circuit is a flip flop, which is toggled by the negative or positive differentiated spikes caused by the falling or rising trigger edges. The trigger polarity can be changed. Trigger input level 4 V ±2 V. It can be 75Ω terminated by internal SW300 on PK8388A. The trigger inputs can be changed to Camera Link input. (TI=0 for CL)

5.3.3. Camera Link interface

The video output is Camera Link with 10 or 8 bit video placed in a base configuration. The digital output signals follow the Camera Link standardized multiplexed signal output interface. The Camera Link output driver is NS type DS90CR285MTD. The data bits from the digital video, FVAL, LVAL, DVAL and EEN are multiplexed into the twisted pairs, which are a part of the Camera Link. Trigger signals and the serial camera control are feed directly through its own pairs. The trigger input can also be TTL on the 12 pin connector. (TI=0 for CL. TI=1 for 12 pin HR). The serial camera control can be switches between the 12 pin connector or CL by the internal switch SW200 on PK8387B. The 26 pin MDR connector pin assignment follows the Camera Link base configuration.

CV-A33CL

6. Functions and Operations

In the following the format shown in “7.3. CV-A33CL command list” are used for function commands and parameters.

6.1. Basic functions

The CV-A33CL camera is a progressive scan camera with 10 or 8 bit video output in single channel Camera Link. Programmable partial scan, where the start line and the number of lines can be selected with 1 line increment is also available. There are 4 modes: Normal continuous, and 3 trigger modes: Edge Pre-Select (EPS), Pulse Width Control (PWC) and Auto Trigger. The accumulation is LVAL a-synchronous. In the following some of the functions are shown in details.

6.1.1. CMOS Sensor

The CMOS sensor principle layout is shown. The sensor is an array of active photosensitive

pixels. The global shutter is working simultaneously on all pixels. The readout can be random row by row. 4 columns are feed through a 4 to 1 multiplexer to an A/D converter. The digitized row signals are placed in a vertical register by a 1 to 4 multiplexing. From here it is read out with the pixel clock pulses, even if the window of interest has fewer columns. The frame speed depends only of the height of the window, not of the width. Pixel principle and column processing with A/D converting is shown below.

6.1.2. Pixel principle

Each pixel consists of a sensing part, a pixel memory and an amplifier. The function can in short be described. The photo diode and charge capacitor is reset when switch 1 is closed. The signal accumulation starts when sw 1 open. The charge is transferred to the pixel memory capacitor when sw 2 close. The accumulation stop when sw 2 open, and the signal is now temporary stored in the memory capacitor. After

reset of the charge capacitor, a new accumulation can start. The signal on the pixel memory capacitor is read out to the column by the read row signal. The memory

can now be reset. With this construction all pixels will integrate at the same time, (Global shutter). The resulting image is temporary stored in the pixel memory during read out, while a new exposure can be started. All timing is set up in the timing block by an internal serial link.
