lane stream mapping
The block placed after the ADC cores is used to implement all functionalities of the
JESD204A standard. This ensures signal integrity and guarantees the clock and the data
recovery at the receiver side.
The block is highly parameterized and can be configured in various ways depending on
the sampling frequency and the number of lanes used.
