A synchronizer and phase aligning method that provide signal smoothing and filtering functions as well as slip-cycle compensation, and allow for multichannel digital phase alignment, bus deskewing, integration of multiple transceivers within a single semiconductor chip, etc. A delay line produces a plurality of delayed input replicas of an input signal. A clock phase adjuster produces a sampling clock signal from a reference clock signal. The sampling clock signal may be phase adjusted to be offset from the input signal. After certain smoothing and filtering functions, selection logic detects a phase relationship between the sampling clock signal and the input replicas and identifies a closely synchronized signal for output. Using this identified replica signal, slip-cycle compensation and retiming logic outputs a compensated data output signal synchronized with the reference clock signal. Also, an integrated multiple transceiver produced using the phase alignment technique is presented.

An LED specification system is provided having at least one LED light output device. The LED light output device has an LED light source, a first exchangeable face panel selectable from a plurality of potential exchangeable face panels, and a housing for locating the exchangeable face panel relative to the LED light source and for orienting the LED light source such that light from the LED light source passes through the first exchangeable face panel. The LED specification system further includes a user interface for selecting at least one preferred output characteristic for light from the LED light output device. The preferred output characteristic is defined by a metric value. The LED specification system further includes a transformation module for defining an LED specification value based at least partially on the defined metric value and a characteristic of the LED light source.

One embodiment of a light emitting diode (LED) lighting device comprises multiple LED light sources disposed on multiple elongated circuit boards, with each LED light source being electrically connected to one of the circuit boards. The elongated circuit boards are electrically coupled using electrical passageways to provide power to the circuit boards at intervals along the length of the elongated circuit boards, and the light sources disposed on the circuit boards emit light in the same direction perpendicular to the elongated circuit boards. The electrical passageways can be wires or groups of wires.
