SN65LVDS324 with IMX172

Hi,

I want to know can SN65LVDS324 be used for  IMX-172 data sample?which mode can be used?

- Sony IMX-172 supports below 6 modes.
  . Mode 0 : 12-bit length, 10 ch output (12M, 34.97 f/s)
  . Mode 1 : 10-bit length, 10 ch output (12M, 39.96 f/s)
  . Mode 2 : 12-bit length,   8 ch output (4K2K, 29.97 f/s)
  . Mode 3 : 12-bit length,  m 4 ch output (4K2K, 14.99 f/s)
  . Mode 4 : 10-bit length, 10 ch output (4K2K, 59.94 f/s)
  . Mode 5 : 12-bit length,   4 ch output (1080p (4K2K binning), 59.94 f/s)
   (* Frame rate can be down to half with register setting)

I think it's not possible to use other modes except Mode 3 & Mode 5 because of LVDS324's performance limit,so can I  use 4-ch subLVDS (4-lane)?But Table 1 has no such description.

Best Regards

Carter

    Hello Carter,

    The LVDS324 only supports two modes for sony sensors, and these modes are parallel 10-bit or parallel 12-bit, both with a sensor clock of 74.25MHz.

    Mode 0 and Mode 1 above seems compatible, but the LVDS324 requires the 12 channels for 12-bit operation and your table says "10 ch output"

    Regards.
