Abstract The stability of the entire base station depends on synchronization station’s clock. clock management chip 8A34002 supports SyncE Ethernet and IEEE 1588. In this architecture, GPS receiver, SSI, master/slave switching device all emit PPS/TOD signals. signals are input into FPGA, which outputs one signal. signal enters in design scheme, DPLL provides filtering clock-following output. 8A...

Clock distribution devices create and distribute multiple copies of a master clock to a variety of integrated circuits (ICs). These devices have single-ended or differential clock inputs and provide multiple outputs (single ended or differential), which are typically divided and delayed versions of the input clock. Low-phase-noise Crystal Oscillators (XOs) are commonly used to drive clock distr...

Conventional digital clock distribution interconnection causes a severe power consumption problem for GHz clock distribution because of transmission line losses, and it exhibits difficult signal integrity problems due to clock skew, clock jitter and signal reflection. To overcome these conventional digital clock distribution limitations, optical clock distribution techniques, based on guided-wa...

Abstract The symbiotic interactions between cancer stem cells and the tumor microenvironment (TME) are critical for progression. However, molecular mechanism underlying this symbiosis in glioblastoma (GBM) remains enigmatic. Here, we show that circadian locomotor output cycles kaput (CLOCK) its heterodimeric partner brain muscle ARNT-like 1 (BMAL1) glioma (GSCs) drive immunosuppression GBM. Int...
