GENERAL DESCRIPTION

The -25 is compliant to the DDR2-800 (6-6-6) specification, the -3 is compliant to the DDR2-667 (5-5-5) specification. All of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks (CLK rising and CLK falling). All I/Os are synchronized with a single ended DQS or differential DQS- DQS pair in a source synchronous fashion. 2.
