3.4 PHYs

The J721S2 device family has several PHYs; for the PHYs with multiple instances, in addition to the mode and the utilization, the user can also select how many of the instances are used:

  • 2x Camera Stream Interface (CSI) 2.0 Receive PHYs each with 4 Lanes
  • 2x CSI2.0 Transmit PHYs each with 4 Lanes
  • Multi Media Card Interface (MMC) for eMMC only
  • 2x Display Subsystem Display Serial Interface (DSI) Transmit interface (using the CSI2.0 Tx PHY)
  • Universal Serial Bus (USB) 2.0 PHY
