Abstract: There is provided a clock phase interpolator comprising a pair of output nodes, at least three complementary clock signal inputs, an equal plurality of current sources, and an equal plurality of clock switching sections. Each clock switching section is connected to switch, under the control of a complementary clock signal on a respective one of the complementary clock signal inputs, the current provided by a respective one of the current sources between the two output nodes. The current sources are controllable to provide interpolation between signals on the complementary clock signal inputs. Also provided is a clock phase interpolator comprising a pair of output nodes, two complementary clock signal inputs, an equal plurality of current sources, an equal plurality of clock switching sections.

Abstract: A steering current generator for a phase interpolator has a multiplicity of fine phase adjustment current sources, each of which is switchable to direct its current to one or other of two summing nodes. The current of each of those two summing nodes is supplemented by respective fixed always-on current sources. The steering current generator has four current outputs and a switching matrix is provided to switch the current from the summing nodes to first and second selected ones of those outputs. The switching matrix is also connected to switch bleed currents to the other two of the current outputs.

Abstract: A coated component for use in a pump or valve. The coated component may be a metal spring and/or ball. Also provided is a container fitted with a pump or valve having such a coated metal spring and/or metal ball for use with a composition that includes a metal ion sensitive ingredient. The spring and/or ball exterior surface is provided with a continuous and durable coating of a polymeric material effective to reduce interaction of metal ions, the metal spring and/or ball, with the ingredient. The coating on the spring is also preferably flexible.

Abstract: Parallel transmitted data in a plurality of channels is synchronised by generating a clock on the basis of the received data and synchronising the data received on each channel with the generated clock signal (50).
