ADC12QJ1600EVM: TI-JESD204C-IP, Assertion of “rx_lane_data_valid”

Part Number: ADC12QJ1600EVM


Hello
I'm tring to run a TI-JESD204C-IP loopback simulation on Vivado(Reference Design: zcu102_64b66b). 
I run the simulation following the steps outlined in the post below.
TI-JESD204-IP: Simulation of loopback design in Vivado - Data converters forum - Data converters - TI E2E support forums 

The user guide states that “rx_lane_data_valid asserts exactly after two cycles,” but in this simulation, it asserts after one cycle. Is this correct behavior?
