A device of the present invention incorporates a data block, received from a Communication Module (CM) connected via an interface, into a frame of a specific format in which a preamble for data synchronization is placed at a head, and transmits the frame to the bus while taking only a data block formed in compliance with an arbitrary Communication Protocol (CP) from a series of frames of the specific format that are constituted from signals detected from the bus. When transmitting data to the bus, the device inserts a code indicating the arbitrary CP into a head part of the preamble, and when a signal corresponding to the head part of the preamble detected from the bus is identified as the code indicating the arbitrary CP, it takes a frame with the identified code to transfer a data block within the taken frame to the CM through the interface.

Method for enabling nodes of heterogeneous communication protocols to share a single bus by adapting to one of the heterogeneous communication protocols and device for said method

A device of the present invention, connected to a Communication Module (CM) via two signal lines, constructs a frame, formatted according to a second Communication Protocol (CP), from bit signals, which are being received from the CM via one signal line, corresponding to data of a frame of a particular format defined by a first CP, to transmit the constructed frame to a bus while transmitting data detected from the bus to the CM via the other signal line in the form of a frame of the particular format. The device measures a width of a pulse signal inserted at a predetermined position in a frame of the particular format being received from the CM first after power on, identifies a bit rate, based on the measured width, at which the CM transceiver data, and applies the identified bit rate to data communication with the CM.

Embodiments according to the application relates to an OFDM (orthogonal frequency division multiplexing) receiving circuit and methods thereof configured to have a plurality of demodulation paths for an oversampling ADC, which can increase or improve an overall performance of the circuit.

OFDM receiving circuit having multiple demodulation paths using oversampling analog-to-digital converter

Embodiments of a phase lock loop and a method for compensating a temperature thereof can output an initial tuning digital value for a voltage controlled oscillator configured to output a desired phase lock loop frequency compensated according to a temperature change. Embodiments of a phase lock loop and a method for compensating a temperature thereof can simultaneously perform a digital coarse tuning and an analog fine tuning to compensate for a temperature in a limited time.
