2.6 Camera Link Implementation
The camera uses National Semiconductor DS90CR287 devices as Camera Link transmitters. For
the Camera Link receivers on your frame grabber, we recommend that you use the National
Semiconductor DS90CR288, the National Semiconductor DS90CR288A or an equivalent. Detailed
data sheets for these components are available at the National Semiconductor web site
(www.national.com). The data sheets contain all of the information that you need to implement
Camera Link, including application notes.
The camera uses a National Semiconductor DS90LV048A differential line receiver to receive the
RS-644 camera control input signals and the serial communication input signal defined in the
Camera Link specification. A DS90LV047A differential line transmitter is used to transmit the serial
communication output signal defined in the specification. Detailed spec sheets for these devices
are available at the National Semiconductor web site (www.national.com).
Camera models with a single MDR connector (see Table 4 and Figure 12 on page 24 ) implement
the "base configuration" as defined in the Camera Link specification and include one differential line
transmitter. The transmitter in the camera is designated as Transmitter X. When a camera is set for
a 2 tap video data output mode, it uses the base Camera Link configuration.
Camera models with two MDR connectors implement the "medium/full configuration" as defined in
the Camera Link specification and include three differential line transmitters. The transmitters in the
camera are designated as Transmitter X, Transmitter Y, and Transmitter Z. If a camera is set for a
4 tap video data output mode, it uses the medium Camera Link configuration and employs
transmitters X and Y. If a camera is set for an 8 tap video data output mode, it uses the full Camera
Link configuration and employs transmitters X, Y, and Z.
Table 5 on page 25 and Table 6 on page 26 show the pin assignments for the MDR connectors.
The schematic in Figure 14 on page 32 shows the full configuration Camera Link implementation
for the camera and a typical implementation for a full configuration frame grabber.
For more information about how the pixel data captured by the camera is assigned to the camera’s
transmitter(s), see Chapter 5 on
page 85 .
Note
Cameras that implement the medium/full configuration can also be used as
base configuration cameras. To do so, simply set the camera for a 2 tap video
data output mode. In this situation, only one Camera Link cable is required.
The cable should be connected to MDR connector 1 on the camera and to the
"base" connector on your frame grabber.
