The gearbox FIFOs provide a flexible data and clock interface for the RF-DAC tiles. However, as with all dual-clock FIFOs, latency might vary between one tile and another. While all channels within a tile have the same latency, some applications might require more than one RF-DAC tile to be used, and require the latencies to be matched across all RF-DAC channels. These applications can use the Multi-Tile Synchronization (MTS) feature to achieve this inter-tile synchronization.
