PCB OF REGISTERED DIMM

摘要

PURPOSE: A PCB of a registered DIMM(Double In-line Memory Module) is provided to compensate the fine characteristics difference of a PLL device by selectively adjusting the length of feedback loop paths of the PLL device for compensating the characteristic difference and the shortage of ideal characteristics according to the kinds of the PLL devices. CONSTITUTION: The registered DIMM is structured to mount a PLL device, and comprises a connecting part(10) and a loop path changing part(20). The connecting part(10) is positioned between a feedback input pin(FBIN) of the PLL device and a ground(GND). The loop path changing part(20) selects a plurality of feedback loop paths different from each other in their path length connecting a feedback output pin(FBOUT) and the feedback input pin(FBIN) of the PLL device.
