Description for the ADC3224EVM
The ADC3224 EVM demonstrates the performance of a low power dual 125Msps 12 bit ADC. It includes the ADC3224 device and TI voltage regulators to provide the necessary voltages. The input for the ADC is connected to a 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. For a complete evaluation system, TI also offers the TSW1400 data capture card and High Speed Data Converter Pro Software.
