• DS1487M/NOPB Application Field and Working Principle

The DS1487M/NOPB is an eight-bit parallel-in, serial-out shift register designed for use in applications where digital data from a parallel data source needs to be encoded into a serial bit stream. It is part of a family of parallel-in/serial-out shift registers from Dallas Semiconductor that provide a digital increase in the length of data words received on a parallel bus.

The DS1487M/NOPB is used in applications ranging from data communication, medical, military and industrial. It provides a low-cost solution to the problem of encryption and serialization of data buses in these types of applications. It is used in various types of data transfer, particularly applications that require high bandwidth and fast response times.

The DS1487M/NOPB is a high performance part, operating at speeds up to8 Mbps in VDD magnitude of 3.3V. The interface is user defined and can be configured to accept various standard parallel interfaces, such as PC/104, DB-15, DB-25, GPIB or IEEE-488, etc, making it an ideal choice for industrial and medical applications.

The application field of the DS1487M/NOPB is mainly in serial data transmission, where it can be used for encoding and transmitting serial data from parallel sources, or for serializing data and sending it to high speed receivers. It operates by transforming parallel in data into serial data, for example it can be used to transmit high speed digital signals from parallel devices over serial lines.

On the other hand, it can also be used in inverse mode, transforming serial data into parallel, so that the data can be processed by various peripheral devices and other circuits. DS1487M/NOPB is capable of generating serial data at the rate of up to8 Mbps and it supports a number of different data formats. This makes it an ideal choice for applications where data rate and data format need to be changed frequently.

The working principle of the DS1487M/NOPB is fairly simple. The device receives eight parallel inputs which are latched and shifted out one by one. When the shift register is clocked, the data from the parallel inputs is moved to the shift register and then shifted out to the serial output. The process continues until all the data is shifted out and then the shift register is reset and ready to receive new data.

TheDS1487M/NOPB has several user configurable settings, such as delay time, data width and clock rate. The settings can be changed through the interface pins which allows the user to adjust the performance of the shift register according to the application requirements. The shift register is also protected against ESD so that it can be reliably used in demanding environments.

In conclusion, theDS1487M/NOPB is a useful device for serializing and transmitting information from parallel Interface. It operates at an impressive 8 Mbps data rate and provides a robust, reliable and easy to use platform for data communication. It can be configured for a number of parallel bus formats and supports a variety of different formats for data transfer. It is perfect for those applications where data rate, data width and data format need to be frequently changed.
