Description
On-Die Termination: ODT enables (when registered HIGH) and disables termination resistance
Input
ODT
R7
internal to the DDR3 SDRAM. When enabled in normal operation, ODT is only applied to each of
the following signals: DQ[63:0], LDQXx\, UDQSx\, UDMx, and LDMx. The ODT input is ignored if
disabled via the LOAD MODE register command. ODT is referenced to VrefCA.
RESET: An input control pin, active LOW referenced to Vss. The RESET\ input receiver is a
CMOS input defined as a rail to rail signal with DC HIGH ≥ 0.8 x Vcc and DC LOW ≤ 0.2 x VccQ.
RESET\ assertion and de-assertion are asynchronous.
