This design is for the PC2-4300,5300,6400/DDR2-533,667,800:

Its VDD supply voltage is 1.8V, and it has SSTL-18 interface for very high-speed operation.
Memory modules need better signal integrity to operate the DDR2-SDRAM stably.
In such a background, we have developed the brand-new PCB CE043, based on our PCB design specifications.
CE043 includes our know-how about design and innovative ideas for stable operation.
CE043, which is made in JAPAN, is a high-quality memory module.
We recommend confidently the CE043 which is CENTURY MICRO's brand-new product.

■ About the wiring on each stacked layer
In order to design a high-quality memory module, it is very important to control accurately the impedance and the wiring length.

In the CE043, all signals are arranged efficiently to each layer.

The wiring density has been reduced on the 3rd inner-layer and the 4th inner-layer to eliminate interference.

The long wiring and essential signals are arranged on the 6th outer-layer, which are shielded by a GND copper plane.

In the CE043, the wiring density of each layer is controlled finely. It will assure absolute stability.
