Digital Parallel and Serial Converters

Digital parallel and serial converters change input streams of parallel data into output streams of serial bits, or vice versa. A digital parallel converter converts data in parallel form into a serial sequence of bits that are at same frequency. A serial converter is an interfacing device that is used to interconnect two serial standards such as USB to RS232. There are many different types of digital parallel converters and serial converters. Examples include a parallel to serial converter, serial to parallel converter, and an analog to digital converter (ADC).

Digital parallel and serial converters achieve parallel to serial conversion with a parallel to serial IC, usually an 8-pin device which works on 5 volts. Parallel to serial conversion is the process of converting the simultaneously received data stream into transmitting one bit at a time. A serial to parallel converter converts the serially received data into multiple data elements that are transmitted simultaneously. It uses a serial parallel adapter and serial to parallel adapter cable to carry out this process. An analog to digital converter samples the analog signals and then converts them into digital form to represent signal of computer processor. Other digital parallel and serial converters are commonly available.

There are several ways in which digital parallel and serial converters work. A parallel to serial IC can be used for logging data to a computer and also for communicating 8 bit data through a serial connection. The data rate of a serial converter is the rate in bits/sec at which the serial data is transmitted. Some examples of specifications of a serial converter include interfaces, indicators for indicating different conditions such as transmission, power-on or collisions, and environmental parameters. A serial parallel adapter consists of one serial port and one parallel port for the printer and does not require any additional power source. A serial to parallel adapter cable supports a bidirectional parallel interface. Some specifications of a analog to digital converter include form factor such as board or IC mount, AC input voltage, AC input current, and DC input current. Digital parallel converters and serial converters are designed and manufactured to meet most industry specifications.

Digital parallel and serial converters are used in many applications. Some examples include digital oscilloscopes, TV tuners, and microcontrollers. Many digital parallel converters and digital serial converters adhere to Electronic Industries Association (EIA) standards for connecting serial devices.
