| Port Name 1 | I/O | Clock | Description |
|---|---|---|---|
| dacXZ_fast_shutdown[2:0] | In | N/A |
RF-DAC fast shutdown 001 - Scale output data by 0.5 011 - Scale output data by 0.25 111 - Scale output data by 0 Others - Normal operation |
| dacXY_pl_event | In | clk_dacX |
RF-DAC PL event Assert to update RF-DAC settings from the PL. |
| dacXY_datapath_overflow | Out | Async |
RF-DAC datapath overflow Asserted when a sub-block in the signal chain has detected that the output signal amplitude has exceeded full scale and has been saturated. |
| dacX_sysref_gate 2 | In | s_axi_aclk | When asserted the sysref is not acted on by the RF-DAC. |
| dacX_sync_out 2 | Out | clk_dacX | This is a one cycle wide pulse that asserts when a sysref event has arrived and indicates the divider values are valid. |
