TI - Commissioning of the Low-Noise MTCA.4-based Local Oscillator and Clock Generation Module J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - Within the Helmholtz Validation Fund Project "MicroTCA.4 for Industry", DESY together with collaboration partners from industry and research developed a compact fully MicroTCA chassis-integrated local RF oscillator module. The local oscillator and clock generation module generates a low noise local oscillator out of the global reference that is distributed over the accelerator. The module includes a splitting section which provides 9 local oscillator signals which are distributed over the RF-Backplane to the rear-transition modules. Similarly, the clock signal is also generated out of a single reference input by means of low-noise dividers. The clock is then fan-out to 22 differential lines that are routed over the RF backplane to the rear-transition modules. The functional block is implemented such that it fits in the rear slots 15 and 14 of a standard MTCA.4 crate. In the paper the commissioning results measured on the L3 low-level RF stations of the European XFEL will be presented.
