Hi
I am FAE in Japanese distributor.
Our customer tries to use AD9713 in JESD Mode3 to output an RF signal of 3GHz ±275MHz from DAC0.
From Table 15 in the AD9173 datasheet, we see that JESD Mode 3 was assigned two lanes.
So we assigned lane0 to I signal data and lane1 to Q signal data.
From Table 13 in the AD9173 datasheet, we see that JESD Mode 3 was assigned Single Channel.
Should we assign I lane0 to Channel0 of DAC0 and lane1 to Channel1 of DAC1?
Best regards

Hi N.Kokubo,
Mode 3 has a single channel per link. Each channel is IQ. The link has M=2, meaning there are two streams, one for I and one for Q (M0Sx and M1Sx below).
Yes, you could split I into DAC0 and Q into DAC1, using the Modulator Switch (a mux). AD9175 has additional modes that allowing using the main NCO.

Hi Landsman san
Thank you for your quick reply.
You mentioned to use Modulator Switch.
Sould we set registor 0x112[5]=0b1 0x112[4]=0b1 ?
Best regards
