SIGNAL TRANSMITTING CIRCUIT USING COMMON CLOCK, AND STORAGE DEVICE THEREWITH

摘要

A transmitting circuit includes a plurality of transmitters, an operation clock generator, and a clock divider. Each of the transmitters outputs data serially. The operation clock generator generates an operation clock signal. The clock divider divides the operation clock signal to generate a symbol clock signal. The plurality of transmitters receives the operation clock signal and the symbol clock signal in common. A clock signal provided to one transmitter is equally synchronized with a clock signal provided to other transmitter(s).

1. A transmitting circuit comprising:
a plurality of transmitters configured to serially output data; an operation clock generator configured to generate an operation clock signal; and a clock divider configured to divide the operation clock signal to generate a symbol clock signal, wherein the plurality of transmitters is configured to receive the operation clock signal and the symbol clock signal in common, and each of the plurality of transmitters includes,
a serializer configured to receive parallel data in synchronization with the symbol clock signal, and to serialize the received parallel data to generate serial data in synchronization with the operation clock signal;digital logic configured to receive original data, to extract data in symbol units from the original data to generate the parallel data, and to provide the parallel data to the serializer based on the symbol clock signal provided through the serializer such that the serializer receives the parallel data in synchronization with the symbol clock signal; anda driver configured to output the serial data.
