Using same REFCLK input with TXENPMAPHASEALIGN enabled for up to four consecutive GTX transceiver sites.
Using PLL_DIVSEL_FB = 2, 20-bit internal data width. These values are NOT intended for protocol specific compliance determinations.
All jitter values are based on a bit-error ratio of 1e
PLL frequency at 1.5625 GHz and OUTDIV = 1.
PLL frequency at 2.5 GHz and OUTDIV = 2.
PLL frequency at 2.5 GHz and OUTDIV = 4.
Using PLL_RXDIVSEL_OUT = 1, 2, and 4.
All jitter values are based on a bit-error ratio of 1e
The frequency of the injected sinusoidal jitter is 80 MHz.
PLL frequency at 1.5625 GHz and OUTDIV = 1.
PLL frequency at 2.5 GHz and OUTDIV = 2.
PLL frequency at 2.5 GHz and OUTDIV = 4.
Composite jitter with RX equalizer enabled. DFE disabled.
