Part Number: DAC38RF89 Hi,
I use DAC38RF89 in wideband DUC mode as figure 33 in the datasheet. I want to add gain to the sum data before DAC core.
Is there a gain block after outputsum block to add a gain to the data before DAC core?
Part Number: DAC38RF89 hi,ti
I am using dac38rf89 in L-M-F-S-HD =82121 (2 TX mode);
costomer board
dac config as followed:
differential input clk :2Ghz
pll on chip unused, dac clock frequency 2Ghz,directly derived from differential input clk
dual dac…
Part Number: DAC38RF89 Hi team,
My customer would like to bias VDDAVCO18 to slightly different voltage from 1.8V but within 1.71V-1.89V range. Should it be OK to do so?
Also, how can the VDDAVCO18 current consumption can be estimated? How much typical…

The cofiguration of DAC38RF89 is follow. I use DUC1 as I data path, and DUC2 as Q data path. I enable the MIXERAB and the NCOAB of the two path, and add adjacent DAC path AB sample(Q data)…
Part Number: DAC38RF89 I config DAC38RF89's JESD204B as fallowing.
It has two real input. One use DACA, the other use DACB.
When I initial DAC38RF89, the two DACs output has a phase difference,t1(two channels data is the same); if I re-initial DAC38RF89…

Hi,
The configuration of DAC38RF89 is as described in section 8.3.16 of the data sheet. The phase of the NCO in Q-channel is set to 90 degrees.
I want to know after the summation,the resault is (I*cosω-Q*sinω) or (I*cosω+Q*sinω…
Hattori-san,
Please see below report for some debug strategies.
whenever serdes block have been changed, we recommend performing another init on the init_Slice to reset the JESD204 core.
thanks.

Part Number: DAC38RF89 The Sync Source Control Register (0x127 or 0x227) has four sync sources(auto-sync from SPI register write,sysref,sync_out from JESD,mem_spi_sync).
What is the difference between them? When should each sync source be used?
Are there…
Hi matt
I have an additional question.
I do not know how to calculate SYSREF.
Table 7-3 shows 4 different calculation methods, but I don't know how to use the different formulas. I don't understand why SYSREF in the GUI has the value it does. Also…
