Hello,
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,
