System Configuration
Clocking
The PL design has two clock domains: AXI4-Lite (register interface) and the video clock. The
video clock drives the AXI4 (memory-mapped), AXI4-Stream peripherals, and the video input
and output interfaces. These domains run at 50 MHz and 148.5 MHz, respectively.
The clock generator module receives the 148.5 MHz input clock from the external clock
synthesizer on the Avnet FMC-IMAGEON card, generates a 37.125 MHz reference clock for
the VITA image sensor, and propagates the148.5 MHz signal as the video clock.
The PS generates the AXI4-Lite 50 MHz clock and the 200 MHz reference clock used to
deserialize the video data from the VITA receiver.
