The core voltage must always be provided at nominal 1.1 V. (See
voltage). Voltage to the processor interface I/Os are provided through separate sets of supply pins and must
be provided at the voltages shown in
associated I/O supply voltage. TV
circuits and satisfy appropriate LVCMOS type specifications. The DDR2 and DDR3 SDRAM interface
uses differential receivers referenced by the externally supplied MV
as is appropriate for the SSTL_1.8 electrical signaling standard for DDR2 or 1.5-V electrical signaling for
DDR3. The DDR DQS receivers cannot be operated in single-ended fashion. The complement signal must
be properly driven and cannot be grounded.
