    ... DDR SDRAM devices on the following rising clock edge (data access is delayed by one clock cycle). A phase-lock loop (PLL) on the module receives and redrives the differ- ential clock signals (CK, CK#) to the DDR SDRAM devices. The register(s) and PLL reduce control, command, address, and clock signals loading by isolating DRAM from the system controller ...

    ... Micron encourages designers to simulate the signal characteristics of the system’s memory bus to ensure adequate signal integrity of the entire memory system. Power Operating voltages are specified at the DRAM, not at the edge connector of the module. Designers must account for any system voltage drops at anticipated power levels to ensure the required supply voltage is maintained. ...
