A continuous-rate clock and data recovery (CDR) circuit that operates from 12.5 Mb/s to 2.7 Gb/s is described. The circuit automatically detects a change in input data rate, acquires the new frequency, and reports the data rate to the user without the need for an external reference clock or any programming. At 2.5Gb/s, it achieves an acquisition time of 1(More)
Melioidosis was first described in Australia in an outbreak in sheep in 1949 in north Queensland (22 degrees S). Human melioidosis was first described from Townsville (19 degrees S) in 1950. Melioidosis is hyperendemic in the Top End of the Northern Territory (NT) and as in parts of northeastern Thailand it is the commonest cause of fatal community-acquired(More)
A 9.95 to 11.1 Gb/s transceiver in 0.13mum CMOS for XFP modules is presented. The CDR uses a dual-loop DLL/PLL to exceed SONET jitter specifications. A half-rate binary phase detector with a 2:1 serializer implements full-rate I/O. Dispersion jitter from 9.5 inches of FR4 is equalized resulting in random jitter(rms) under 4mUI. Power consumption is 800mW
A 9.95-11.3-Gb/s transceiver in 0.13-mum CMOS for XFP modules is presented. The CDR uses a dual-loop DLL/PLL with a binary phase detector to exceed XFP jitter specifications. The dual loop solves the problem of having a controlled jitter transfer bandwidth with a binary phase detector. A half rate binary phase detector with a 2:1 serializer implements(More)
The Internet of Everything (IoE) is a macro trend that is presently disrupting the global electronic industry. Tremendous growth is forecast in the areas of sensing, measurement and the interpretation of data, before transferring to the Cloud for analysis. This exponential increase in wireless-sensor traffic, coupled with increasingly harsh environments in(More)
The mol-ecule of the title compound, [Pb(C(16)H(16)NS(2))(2)], is located on a twofold rotation axis, which runs through the Pb(II) atom. The two dithio-carbamate ligands coordinate the metal in a pyramidal configuration through the S atoms. The two phenyl rings of each dithocarbamate ligand are aligned at a dihedral angle of 78.4 (1)°. The mol-ecular(More)
In the title compound, C(26)H(25)NO(3), both pyrrolidine rings adopt envelope conformations, whereas the dihydro-pyran ring adopts a half-chair conformation. The phenyl ring is oriented at an angle of 27.9 (1)° with respect to the naphthalene ring system. An intra-molecular C-H⋯O hydrogen bond is observed. The crystal packing is stabilized by weak(More)
In the title carbazole derivative, C32H32N2, the mol-ecule resides on a crystallographic twofold axis, which runs through the central C-C bond. The carbazole ring system is almost planar, with a maximum deviation of 0.041 (1) Å for one of the ring-junction C atoms. The crystal packing is stabilized by C-H⋯π inter-actions only, which form a C(7) chain-like(More)
The title compound, C20H18N2O·CH3CN, a perimidine deriv-ative, crystallized as an aceto-nitrile monosolvate. The planes of the naphthalene ring system and the meth-oxy-phenyl ring are oriented almost perpendicular to one another, with a dihedral angle of 87.61 (6)°. The conformation about the C=C bond is E. The hexa-hydro-pyrimidine ring has an envelope(More)
In the title indole derivative, C20H18ClNO2, the chloro-phenyl ring is almost perpendicular to the indole moiety, making a dihedral angle of 87.6 (1)°. The mol-ecular packing is stabilized by C-H⋯π inter-actions, which form a C(9) chain motif along [10-1]. In addition, there are weak π-π inter-actions [centroid-centroid distance 3.851 (1) Å] between the(More)
