Clock Sources
The Zynq 7Z045 Mini-Module Plus Development Board used in conjunction with the Mini-Module
Plus Baseboard 2 includes all of the necessary clocks to implement high-speed logic and GTX
transceiver designs. Most of these ma
ster clocks are sourced from the baseboard’s FMC connector
and the on-board LVDS clock synthesizer. All of these clocks are tied to the Z7045 MRCC pins
giving access to the 7Z045’s global clock tree. The clock sources described in this section are used
to derive the required clocks for the memory and communications devices, and the general system
clocks for the logic design. For a description of the GTX reference clock sources, see Section 2.2.1.
The following figure shows the clock nets connected to the I/O banks of the 7Z04.
