DS280DF810: Reference clock routing to multiple retimers

Part Number: DS280DF810

When using a single reference clock for up to 20 retimers, do you need to have a termination resistor in between each retimer? The datasheet specifies: No AC coupling or resistor ladder is needed between one retimer’s CAL_CLK_OUT output and the next retimer’s CAL_CLK_IN. It does not specify if  a termination resistor is required between one retimer's CAL_CLK_OUT output and the next retimer's CAL_CLK_IN.
