Camera Link Implementation In The A500K - Basler A500k User Manual

2.3 Camera Link Implementation in the A500
The A500 uses a National Semiconductor DS90CR287 as a Camera Link transmitter. For a
k
Camera Link receiver, 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.
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 which allow you to select either
rising edge or falling edge sampling. Please consult the data sheet for the receiver
that you are using for specific timing information.
The A500 uses a National Semiconductor DS90LV048A differential line receiver to receive the
k
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).
