Figure 7–9. Arria GX, Stratix II GX, or Stratix IV GX PHY ×1 and ×4 and Arria II GX ×1, ×4, and ×8
with 100 MHz Reference Clock
Note to
(1) Different device families require different frequency ranges for the calibration and reconfiguration clocks. To
100 MHz Reference Clock and 250 MHz Application Clock
When HardCopy IV GX, Stratix II GX PHY, Stratix IV GX, or Stratix V GX is used in a
×8 configuration, the 100 MHz clock is connected directly to the transceiver. The
clk250_out is driven by the output of the transceiver.
The clk250_out must be connected to the clk250_in input, possibly through a clock
distribution circuit needed in the specific application. The user application interface is
synchronous to the clk250_in input.
