Draft
2.3 Camera Link Implementation in the L800k
The schematic in Figure 2-3 shows the interface for
L800
k
cameras and a typical implementation
for the frame grabber interface.
The
L800
k
uses a National Semiconductor DS90CR285 as a Camera Link transmitter. For a
Camera Link receiver, we recommend that you use the National Semiconductor DS90CR286, the
National Semiconductor DS90CR286A 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 you need to implement Camera Link, including application
notes.
The
L800
k
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 DS90LV011A 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).

Note that the timing used for sampling the data at the Camera Link receiver in the
frame grabber varies from device to device. On some receivers, TTL data must be
sampled on the rising edge of the receive clock and on others, it must be sampled
on the falling edge. Also, some devices are available that allow you to select either
rising edge or falling edge sampling. Please consult the data sheet for the receiver
you are using for specific timing information.
