Clock domain crossing is when data must cross between one clock domain (area of hardware running on a clock of one given frequency) to another clock domain with a different frequency. Key challenges are maintaining data integrity of any data over the crossing (data is correct, and nothing is missing) and avoiding any metastability from as a result of the crossing.
