Hello!
We are going to use the ADS42B49 device in our application. My question is regarding the reference design that are provided in the ADS42B49EVM board schematic.
In the eval board schematic and BOM file the part number of the T1 and T2 transformers are given as WBC1_1TL.
The datasheet of the WBC1_1TL (coilcraft) provides the following schematic symbols for WBC1_1TL transformers.
The schematic symbol given in the eval board schematic is not compliant with the schematic symbols given in the datasheet.
The dods points are located in the different pins as given below. Is this a typo or is there a specific reason for this?
My second question is that, the secondary coils of the T1 and T2 transformers are connected to each other.
Could you please help me to see the logic behind this connection? Normally I expect, the secondary coil of the T1 should be connected to the primary part of the T2 transformer.
Kind regards
Sam
