3.3.3
This chapter describes the ODT AC electrical characteristics.
1) New units, “t
2) ODT turn on time min is when the device leaves high impedance and ODT resistance begins to turn on. ODT turn on time max is when
3) 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.
1) ODT turn on time min. is when the device leaves high impedance and ODT resistance begins to turn on. ODT turn on time max is when

the ODT resistance is fully on. Both are measured from
2 clock cycles after the clock edge that registered a first ODT HIGH counting the actual input clock edges.
Both are measured from
ns (= 0.5 x 3 ns) after the second trailing clock edge counting from the clock edge that registered a first ODT LOW and by counting the
actual input clock edges.
the ODT resistance is fully on. Both are measured from
10 ns (= 2 x 5 ns) after the clock edge that registered a first ODT HIGH if
