SJM187BCC Application Field and Working Principle

SJM187BCC is a type of compact, cost-effective device that can be used in a variety of applications, ranging from analog switches, multiplexers and demultiplexers to interface-specific functions. It is available in a variety of packages optimized for specific application requirements.

Analog Switches & Multiplexers

Analog switches and multiplexers are digital control devices used to switch between a desired analog signal and another, or to control the flow of analog signals in a multiplexed stream. The SJM187BCC is an integrated digital-to-analog switch designed to provide all the essential circuits to switch up to three analog signals, a process which simplifies system design and provides a cost-effective solution. Furthermore, the ability to support digital control of analog signals allows for various functional settings such as changing input channel, muting, or other settings.

Demultiplexers

Demultiplexers are digital circuits that are used to separate a multiplexed stream of analog signals back into their original form. The SJM187BCC is a high-speed, low-power integrated circuit that can separate up to three input channels into individual channels.

Working Principle

The working principle of the SJM187BCC is based on an input muxer, which is a digital circuit that can switch between multiple input signals. The muxer is connected to a group of analog switches, which are then connected to one or more analog multiplexers. The muxer is then in turn connected to a group of digital-to-analog converters. The digital control signals from the digital control circuit drive the analog multiplexers to map the analog signals from different channels in real-time. During the operation, the SJM187BCC can switch up to three analog signals.

Conclusion

The SJM187BCC is a cost-effective, high-speed digital integrated circuit designed to provide all the essential circuits to switch up to three analog signals. It can be used in a variety of applications, such as analog switches, multiplexers and demultiplexers, as well as for interface-specific functions. Its working principle is based on an input muxer, analog switches and a group of digital-to-analog converters, and it can support digital control of analog signals.
