Fs = 2.94912 GHz, 5-Sample Example
This example captures data from channel A of the ADC32RF45 EVM sampling at 2.94912 GHz with a
1900-MHz input source. This procedure uses a .cfg file to set up the LMK04828 clock device first, and
then another .cfg file to set up the ADC. This is always the required sequence. The ADC requires the
device clock and SYSREF signals to be present before the ADC can be properly configured.
1. Open the ADC32RFxx EVM GUI.
2. Verify that the green USB Status indicator is lit. If it is not lit, click the Reconnect? button and check the
USB Status indicator again. If it is still not lit then verify the EVM is connected to the computer through
USB. Whenever the USB link is disturbed, the GUI must obtain a new handle to address the proper
USB port, and the Reconnect? Button does that.
3. On the PLL1 tab of the LMK04828 tab, press the RESET button.
