Note that the JEDEC SSTL_18 specification (JESD8-15a) for a SSTL interface for class II operation supersedes any
specification in this document.
OVDD is the I/O power supply (1.7 V–1.9 V for DDR2)
(Vout - OVDD) / Ioh must be less than 21 Ω for values of Vout between OVDD and OVDD-0.28 V.
Vout / Iol must be less than 21 Ω for values of Vout between 0 V and 280 mV.
Vin(dc) specifies the allowable DC voltage exertion of each differential input.
Vid(dc) specifies the input differential voltage |Vtr-Vcp| required for switching, where Vtr is the “true” input level and Vcp is the
“complementary” input level. The minimum value is equal to Vih(dc) -Vil(dc).
Typ condition: 1.8 V, and 25 °C. Max condition: 1.9 V, and 105 °C.
Use an off-chip pull resistor of less than 60kΩ to override this keeper.
