摘要： A deserializer circuit and method convert a serial bit stream into a parallel bit stream according to a parallel grouping. The deserializer and method include alternatingly demultiplexing a serial data stream into first and second bit streams. The first and second bit streams are respectively serially shifted along a first plurality of shift registers and a second plurality of shift registers. A first portion of the first bit stream in the first plurality of shift registers is selected and a second portion of the second bit stream in the second plurality of shift registers is also selected. A parallel group of data in a parallel data stream is formed from the first and second portions.

摘要： Provided is a disdrometer system having a three-dimensional laser array unit, including: a plurality of laser transmitting parts which are arranged on an inner side of a cylindrical body to generate a laser beam; a plurality of laser receiving parts which are arranged on the inner side of the cylindrical body to correspond to the laser transmitting parts; and a laser control part which converts a cut-off signal of the laser beam, which is cut-off by precipitation drops flowing into the inner side of the cylindrical body, into an electrical signal, and records the converted electrical signal. Thus, the disdrometer system has an effect that the shape, volume, number, falling velocity of precipitation drops, and the intensity, density and weight of rainfall can be integrally measured.

摘要： A level shifter includes an inverting circuit, a cross-coupled level shifting latch, and a SR logic gate latch. The first and second outputs of the level shifting latch are coupled to the set (S) and reset (R) inputs of the SR latch. The inverting circuit, that is powered by a first supply voltage VDDL, supplies a noninverted version of an input signal onto a first input of the level shifting latch and supplies an inverted version of the input signal onto a second input of the level shifting latch. A low-to-high transition of the input signal resets the SR latch, whereas a high-to-low transition sets the SR latch. Duty cycle distortion skew of the level shifter is less than fifty picoseconds over voltage, process and temperature corners, and the level shifter has a supply voltage margin of more than one quarter of a nominal value of VDDL.

摘要： Serializers and deserializers for odd ratio parallel data buses are disclosed. In one embodiment, serializers and deserializers operating with an odd number of parallel data bits work with a half-rate clock to provide a serial data stream at a full clock rate. By providing a half-rate clock, power and area are conserved on the integrated circuit incorporating the serializer. Additionally, by providing a 7:1 serializer, the bus is now compatible with the MIPI C-PHY standard.
