According BECKHOFF specification in regard to clock supply for PHY connection the initial PHY clock source has to be 25ppm or better:

"3.2 Clock supply
The initial accuracy at room temperature of the PHY clock source has to be 25 ppm or better. This enables
FIFO size reduction, i.e., forwarding delay reduction, and supports fast DC locking."
