May 8, 2013KM3NeT, CLBv2 Meeting Peter Jansweijer Mesfin Gebyehu Nikhef Amsterdam Electronics- Technology Done: ◦ LM32 + WB-Crossbar + DPRAM + UART ◦ Soft-PLL FMC layout ◦ WR without PCI-express Currently: ◦ Deterministic PHY ◦ Soft PLL (hardware + software). First goal: lock onto a 125 MHz xtal and phase shift under control of LM32 via UART To do (in order of priority): ◦ Endpoint (= MAC) <= Complex! ◦ Mini-nic <= Complex! ◦ Fabric redirector <= probably less complex ◦ PPS generator <= relatively straightforward ◦ 1-wire, SysCon <= easy?

May 8, 2013KM3NeT, CLBv2 Meeting Peter Jansweijer Mesfin Gebyehu Nikhef Amsterdam Electronics- Technology KC705 crystal X3 is of target frequency 8 Changed to 27 pf Frequency of the (“Master Node”) crystal ~ +25 ppm off the target (SGMIICLK_Q0 = ). The “Slave Node” VCXO doesn’t lock (out of VCXO pulling range). Soft-PLL FMC U12 outputs (midrange) which is ~ -4 ppm of target. Change C93, C94 => master frequency = => VCXO Locks!
