Clock Networks
Global Clocks
There are eight global clock networks in each QL8325 and QL8250 device, and five global clock networks in
each QL8150, QL8050 and QL8025 device. Global clocks can drive logic cells and I/O registers, ECUs, and
RAM blocks in the device. All global clocks have access to a Quad Net (local clock network) connection with
a programmable connection to the logic cell’s register clock input.
Figure 11: Global Clock Architecture
Quad-Net Network
There are five Quad-Net local clock networks in each quadrant for a total of 20 in a device. Each Quad-Net is
local to a quadrant. Before driving the column clock buffers, the quad-net is driven by the output of a mux
which selects between the CLK pin input and an internally generated clock source (see Figure 12).
