We are sending SINE wave using ADRV 9002 connected to custom FPGA with sampling rate of 1MHZ. We have configured SSI type as LVDS, SSI data format as 16_BIT_I_Q.
SINE wave is stored as LUT (1024 samples each of 16bit for complete SIN wave ). We are reading LUT with 1MHz and sending it to IOD. We are Transmitting data via TX2 and Receiving on RX2 to check our design data and control paths. Calibrations are successful but we are noticing glitches at the ADRV TX when we observed in oscilloscope.
We think this could be the problem with Filters at TX. We tried changing the filter coefficients (we generated coefficients from MATLAB) but problem remains the same. We tried changing sampling frequencies still the issue is present. Could anyone help us solving this issue ?
