Camera Link Implementation in the 102 The 102 uses a National Semiconductor DS90CR287 as a Camera Link transmitter For a 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 A102k 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
