Description for the ADC3442EVM
The ADC3442EVM Evaluation Module demonstrates the performance of a low power quad 50Msps 14 bit ADC. It includes the ADC3442 device and TI voltage regulators to provide the necessary voltages. The input for the ADC is by default connected to the transformer input which can be connected to a 50 ohm single ended signal source. The clock input is provided via a transformer input and can be connected to a 50 ohm single ended clock source. A SYSREF input is provided to allow complete system synchronization. Register access is provided through the on board USB connection and a GUI.
