Disclosed is a clock phase aligning apparatus capable of synchronizing a clock signal in the middle of an upstream burst mode data bit in an optical line terminal of a passive optical network. The clock phase aligning apparatus effectively aligns a phase of a clock signal with a phase of data during an overhead period of burst mode packet data through an over-sampling scheme and a digital scheme. Burst mode data signals are subject to an over-sampling through a high speed continuous mode analog circuit and then converted into low speed parallel signals through a parallel conversion unit. Such low speed parallel signals are processed with respect to sampling patterns through a digital look-up scheme in a logic circuit device such that the phase of data is arranged with the phase of a clock signal during a limited bit stream specified in a burst mode preamble timing.

Disclosed herein is a muffler of a scroll compressor. The muffler includes a first muffler having a pair of chambers defined above an outlet of a fixed scroll to communicate with the outlet and a gas passage hole formed at the center of an upper end thereof, and a second muffler located around the first muffler to be spaced apart from the gas passage hole of the first muffler and having a chamber including one or more guidance paths of the fixed scroll. The muffler can achieve reduction of operational noise, sufficient separation of oil contained in discharge gas, and efficient isolation between a discharge pressure inside the muffler and outside suction pressure.

A method and apparatus for controlling the timing of a state transition of a serial data line (SDA) in an I2C controller are provided. The apparatus includes a processor, a serial clock line (SCL) edge detector, a counter, and an SDA generator. The processor controls an I2C controller. The SCL edge detector detects an edge of a clock signal of an SCL. The counter counts a hold time of the state transition of the SDA if a falling edge of the clock signal of the SCL is detected by the SCL edge detector. The SDA generator transits the state of the SDA if the count of the hold time is finished. Therefore, a malfunction in an I2C communication can be prevented without using a compensation circuit requiring a lot of time and cost.
