8.10. Interlaken PHY PLL Interface
Signal Name | Direction | Description |
---|---|---|
pll_ref_clk | Input | Reference clock for the PHY PLLs. Refer to the Lane rate entry in the Table 100table for required frequencies. Custom, user-defined, data rates are now supported. However, the you must choose a lane data rate that results in standard board oscillator reference clock frequency to drive the pll_ref_clk and meet jitter requirements. Choosing a lane data rate that deviates from standard reference clock frequencies may result in custom board oscillator clock frequencies which could be unavailable or cost prohibitive. |
