Table 3-12. External Reference Clock Specification (refclkp/refclkn)
Lattice Semiconductor
SERDES External Reference Clock
The external reference clock selection and its interface are a critical part of system applications for this product.
Table 3-12 specifies reference clock requirements, over the full range of operating conditions.

1. Depending on the application, the PLL_LOL_SET and CDR_LOL_SET control registers may be adjusted for other tolerance values as
2. The signal swing for a single-ended input clock must be as large as the p-p differential swing of a differential input clock to get the same gain
