The ADC3244 evaluation module (EVM) demonstrates the performance of the ADC3244, which is a low-power, dual-channel, 14-bit, 125-MSPS analog-to-digital converter (ADC). The board includes the ADC3244 device and TI voltage regulators to provide the necessary voltages.
The input for the ADC is connected to a transformer input that can be connected to a 50-Ω single-ended signal source. The clock input is provided via a transformer input and can be connected to a 50-Ω single-ended clock source. A SYSREF input is provided to allow complete system synchronization. Register access is provided through the onboard USB connection and a GUI.
For a complete evaluation system, TI also offers the TSW100EVM data capture card and high-speed data convert pro software (DATACONVERTERPRO-SW).
