IP: Altera PHYLite for Parallel Interfaces

Why can't the interface clock frequency be set to a value between 137.5MHz to 149.9MHz for the Intel® Arria® 10 PHYLite IP when using quarter rate mode?

Description

Due to the PLL VCO setting limitation, the Intel® Arria® 10 PHYLite IP doesn’t support the frequency range between 137.5MHz to 149.9MHz when using quarter rate mode.
