Notes:
1. Using RXOUT_DIV = 1, 2, and 4.
2. All jitter values are based on a bit error ratio of 1e
–12
.
3. The frequency of the injected sinusoidal jitter is 10 MHz.
4. PLL frequency at 3.2 GHz and RXOUT_DIV = 2.
5. PLL frequency at 1.6 GHz and RXOUT_DIV = 1.
6. PLL frequency at 2.5 GHz and RXOUT_DIV = 2.
7. PLL frequency at 2.5 GHz and RXOUT_DIV = 4.
8. Composite jitter.
