Dec Zhen'An LIU7 Others bought or ordere except 5

Dec Zhen'An LIU8 Components missing  SODIMM FOXCONN AS0A42x-N4Sx-xx. The price is about RMB24/pc, and the MOQ is 560.  RJ45 we ordered the 60 pcs  SAMTEC 60PIN CONNCTOR. we asked tiago for help in Giessen, (we need 4 pcs for each board)  MAX16003ETE, Maxim. The vendor said that it will be 17 weeks to get the components. failed to ask for samples. digikey (de.digikey.com). We need 1 pcs for each board.  7511B11, CML. 3 high light pipe used on front panel. The digikey part number on digikey web is L70580-ND. We need 8 pcs for each board.

Dec Zhen'An LIU9 old Plan (Sep )  Schematic has been finished 15 Apr. V Aug. V1.1  Components are under booking  Layout is under way  PCB version 1.0 will be finished before November.

Dec Zhen'An LIU10 Current Status(1)  Layer Stacks More space needed for routing, so number of layers Changed from 12 to14 layers in total 8 Signal layers 3 GND layers 3 VCC layes

Dec Zhen'An LIU11 Current Status(2) Layout of DDR2 SODIMM  Hardware and layout design must be considered carefully for DDR2 SDRAM memory interfaces: Serpentine loops to match the data lane within 10 mils, All data lanes are matched with 0.5 inch, …

Dec Zhen'An LIU12 Current Status(3)  Time Consuming: DDR2 socket Interconnection  85% finished DDR2 SODIMM Virtex4-FX60 Optical Transceivers Gigabit Ethernet Power Modules
