The Altera IOPLL megafunction IP core allows you to configure the settings of Arria

10 I/O PLL.

Altera IOPLL IP core supports the following features:

• Supports six different clock feedback modes: direct, external feedback, normal, source synchronous,

zero delay buffer, and LVDS mode.

• Generates up to nine clock output signals for the Arria 10 device.

• Switches between two reference input clocks.

• Supports adjacent PLL (adjpllin) input to connect with an upstream PLL in PLL cascading mode.

• Generates the Memory Initialization File (.mif) and allows PLL dynamic reconfiguration.

• Supports PLL dynamic phase shift.
