Output Power TE0835-03-TXE81-A

Can anyone suggest the DAC output level of the TE0835-03-TXE81-A?

Lets presume a 10KHz bandwidth FSK waveform operating around 250MHz.

Thanks,

Hi Nate,

the TE0835-03-TXE81-A module features a zu47dr RFSoC chip(GEN3). The DAC has a resolution of 14 bits. The DAC_AVTT pin (reference voltage of the DAC) is connected to 2.5V. You can then calculate the output level of the DAC as follows:

Vout(LSB) = Vref/(2^14-1)=152.6 uv

In the RF converter IP core in Vivado, the output current of the DAC can be configured to 20mA or 32mA. The DAC output level is configurable and depends on the respective device generation and current mode selected in the RF converter IP core. The DAC output range is variable and decreases as the signal frequency increases.
