LVDS Interface Configuration

The supported IWR6843 LVDS lane configuration is two Data lanes (LVDS_TXP/M), one Bit Clock lane (LVDS_CLKP/M) and one Frame clock lane (LVDS_FRCLKP/M). The LVDS interface is used for debugging. The LVDS interface supports the following data rates:

  • 900 Mbps (450 MHz DDR Clock)
  • 600 Mbps (300 MHz DDR Clock)
  • 450 Mbps (225 MHz DDR Clock)
  • 400 Mbps (200 MHz DDR Clock)
  • 300 Mbps (150 MHz DDR Clock)
  • 225 Mbps (112.5 MHz DDR Clock)
  • 150 Mbps (75 MHz DDR Clock)

Note that the bit clock is in DDR format and hence the numbers of toggles in the clock is equivalent to data.
