The recommendations for Balun's for DAC (DAC38RF82) was not mentioned in datasheet.
In the DAC EVM recommended part no: TCM3-452X-1+. This Balun having high phase imbalance.
Can we use TCM2-63WX+.How design then Balun ?

Mingming,
You may want to add a cap on the power net input to both L3 and L4 inductors to filter out any noise on this DC signal. This is the reason for C364 and C402 on the TI DAC38RF82EVM schematic.

Jim
Hi Mingming, I've removed my earlier post entirely as it contained misleading information, my apologies for that. Please see the image below showing what Jim describes above.
