TSW40RF80EVM: GUI DAC38RF8x-Quick Start Reset DAC JESD Core & SYSREF TRIGGER Button

Part Number: TSW40RF80EVM

TSW40RF8x EVN GUI DAC38RF8x-Quick Start tag
Reset DAC JESD Core & SYSREF TRIGGER button,
What kind of processing are you doing?
I have confirmed that the SYSREF TRIGGER signal is output when the button is pressed.

In the datasheet User's Guide SLAU706A-January 2017-Revised September 2017,
Press the Reset DAC JESD Core & SYSREF TRIGGER button There is no explanation, but
If I didn't press the button, the DAC wouldn't output.
The ADC was unable to start the FFT.

  • Hi,

    This processes forces the DAC JESD204B RX state machine to be reset, reinitialized again by the SYSREF pulse, and start the re-handshake of the JESD204 link. You should see the SYNCOUT from the DAC JESD204B RX IP core to toggle to request for K28.5 signal from your FPGA.
