Registered DDR2 SDRAM Modules
2) ODT turn off time min. is when the device starts to turn off ODT resistance. ODT turn off time max is when the bus is in high impedance.
Both are measured from
t
. Both are measured from
t
, which is interpreted differently per speed bin. For DDR2-400/533,
t
AOFD
is
12.5 ns (= 2.5 x 5 ns) after the clock edge that registered a first ODT HIGH if
t
CK
= 5 ns.
