Schematics: ------------ * C165 value changed from 100nF to 220nF * VCC_IN of CDCM61002 (IC13) connected to +3V3 * RSTN pin of IC13 conected to a 47nF capacitor, not to +3V3 * QDRII_200CLK moved to OUT3 (LVPECL) of AD9516. * Added LVDS termination resistor to adapt OUT3 to LVDS format * CLK_OUT (EXTREF125MHZOUT) connected to OUT9 (CMOS) of AD9516-4. * CLK_OUT transformer changed by 1:1 (WBC1-1LB) * R253 and R254 resistor (Ethernet sheet) changed to 0402 size in order to reduce items. * Changed EXTPPSIN input stage in order to add 50 R termination selectable by the FPGA. * Name of nets QDRII_CLK and QDRII_200CLK changed to REF_CLK and AUX_CLK. * Input EXTREF_125M removed. * QDRII IC42 chip removed. * Added ouput from FPGA latched by an AD9516 clock. This output uses the EXTREF_125M SMC connector: * Added LVPECL latch * Added LVPECL to LVTTL translator at the output * CLK0 input of IC12 changed to OUT6 of AD9516 * FPGA VCCO Bank 26 changed to +2V5 to use LVPECL and LVDS * Removed the six 0R resistor at the inputs of the AD5662 DACs * FPGA Banks 26, 36 and 25 moved to "PFGA_Peripherals_Control" sheet. * Connected the 3 free buffers SN74LVT125DW to the EXTPPSOUT output signal. PCB: ------ * GTX_DIFF signals routed on 90um/160um in order to reduce space, allowing to pass between vias * Some vias were moved from pads of some components to avoid the solder paste flooding by the vía. * IVT3200 VCO was moved to separate it of NAND Flash IC
