Altera SDI II MegaCore - Manual (Page 30)

The Arria 10 design example for the SDI II IP core consists of the following components:
• Video pattern generator
• Transceiver reconfiguration controller
Video Pattern Generator
The video pattern generator generates a colorbar or pathological pattern. The colorbar is preferable for
image generation while the pathological pattern can stress the PLL and cable equalizer of the attached
video equipment. You can configure the video pattern generator to generate various video formats.
Table 3-5: Configuring the Video Pattern Generator to Generate Different Video Formats
Table below lists the examples of how to configure the video pattern generator signals to generate a video format
that you desire.

Transceiver Reconfiguration Controller
The transceiver reconfiguration controller reconfigures the transceivers. The transceiver reconfiguration
controller in the Arria V, Cyclone V, and Stratix V design examples and the Arria 10 design example is
used differently.

Transceiver Reconfiguration Controller for Arria 10
For Arria 10 design examples, the reconfiguration interface is integrated into the Arria 10 Native PHY
instance and TX PLL. Each transceiver and PLL contains an Avalon-MM reconfiguration interface that
must be connected to this reconfiguration controller user logic.
