About the terminator of DDR3L memory of LS1020A.

I am watching a connection diagram of LS1021A-twr.


A terminating resistance of CLK of DDR3 of P1010RDB is just between± 100 Ω.

LS1021A-twr adds a condenser to 72 Ω of resistance, and is connected to GVDD.


Is this circuit the specification of LS102xA? Or is there a different reason?

In particular, I can't understand the reason that a condenser exists by this circuit.


Best Regards,
