Data transmission device for transmitting converted data at a controlled transmission rate

Abstract

A data transmission device for converting parallel data into serial data and setting the transmission rate the converted data according to an arbitrary value of time data. The data transmission device includes a first input latch for latching N-bit parallel time data in response to a first input enable signal, and a transmission clock generator for generating a transmission clock signal by counting a system clock signal according to the latched N-bit parallel time data. It also includes a second input latch for latching N-bit parallel transmission data in response to a second input enable signal, and an output selection signal generator for counting the transmission clock signal in response to the second input enable signal and generating the counted value as an output selection signal. Further, the device includes a serial-to-parallel converter for converting the latched N-bit parallel transmission data signal into an (N+2)-bit serial data output signal in response to the output selection signal.
