  1. Using same REFCLK input with TX phase alignment enabled for up to four consecutive transmitters (one fully populated GTY or GTYP Quad) at maximum line rate.
  2. Using LCPLL_FBDIV = 40, 20-bit internal data width. These values are NOT intended for protocol specific compliance determinations.
  3. Using RPLL_FBDIV = 10, 20-bit internal data width. These values are NOT intended for protocol specific compliance determinations.
  4. All jitter values are based on a bit-error ratio of 10–12.
