property loopback_mode

loopback_mode: Enable loopback mode RX->TX

When enabled JESD RX FIFO is connected to JESD TX FIFO, making the entire datasource for the TX path the RX path. No data is passed into the TX path from off-chip when 1. For this mode to function correctly the JESD configuration between RX and TX must be identical and only use a single link.

property path_map

path_map: Map of channelizers both coarse and fine to individual driver channel names

property pfilt_config

property powerdown

powerdown: Powerdown and reset the chip

Support for dynamic powerdown. Writing device attribute powerdown with ‘Yy1Nn0’, or [oO][NnFf] for “on” and “off”, will either stop the jesd204 fsm, reset the device and power down an optional regulator (vdd), or do the opposite in reverse order.

property tx_dac_en

tx_dac_en: Enable DACs

property tx_dac_full_scale_current

property tx_ddr_offload

tx_ddr_offload: Enable DDR offload

When true the DMA will pass buffers into the BRAM FIFO for data repeating. This is necessary when operating at high DAC sample rates. This can reduce the maximum buffer size but data passed to DACs in cyclic mode will not underflow due to memory bottlenecks.

property tx_main_ffh_frequency

tx_main_ffh_frequency: Transmitter fast frequency hop frequency. This will set The NCO frequency of the NCO selected from the bank defined by tx_main_ffh_index

property tx_main_ffh_gpio_mode_enable
