Hi, Sir, from signal measurement, DACCLK always working and have good signal quality. But we are using FPGA+DAC3484, FPGA LVDS output transform to LVPECL by AC couple. refer
TIDA-00077 , can you help to confirm it is OK? or we should use DC couple?
Izik,
In general it is not a good idea to drive 1 common IQ source into 2 IQ modulators. The problem is that there will be different analog impairments for each IQ modulator and you cannot do any compensation or correction in the DAC or digital baseband…
