receiver channel-to-channel skew (RCCS) Definition

In designs that use the LVDS I/O standard, receiver channel-to-channel skew (RCCS) is the timing difference between the fastest and slowest input transitions, including tCO variations and clock skew. RCCS is specified by applying minimum and maximum set_input_delay constraints to the receiver inputs, where RCCS is the difference between the maximum and minimum value.
