3.5.1. Using the Duplex Feature

The Intel® Stratix® 10 device does not support PLL merging. However, the duplex feature allows placing transmitters and receivers in the same I/O bank. The duplex feature is a simpler option compared to using an external PLL.
  • To use the duplex feature, turn on the Duplex Feature option of the LVDS SERDES IP core.
  • The number of transmitter and receiver channels in the IP core instance is the same.
  • The limitation is that you can create only up to 11 transmitter and 11 receiver channels in each LVDS SERDES IP core instance.
  • The LVDS SERDES IP core sets up PLL sources for the transmitters and receivers in the IP core instance.
