Toshiba's New Digital Isolator Enables Stable High-Speed Isolated Data Transmission for Industrial Applications
【Lansheng Technology Information】May 9, 2023 - Toshiba announced the launch of the new high-speed four-channel digital isolator "DCL54xx01" series, which has a high common-mode transient immunity (CMTI) of 100kV/μs (min) and 150Mbps high-speed data rate.
To ensure the safety and reliability of factory automation equipment, isolation devices are required to ensure insulation and prevent noise transmission. Toshiba provides digital isolator solutions to meet industrial applications' requirements for higher speed, multi-channel signal communication, and high CMTI.
The new product uses Toshiba's proprietary magnetic-coupled isolation transmission method, which provides a high CMTI of 100kV/μs (min)[1]. This not only realizes high tolerance of electrical noise between input/output in isolated signal communication, but also contributes to stable control signal transmission and device operation. This digital isolator has a low pulse width distortion of 0.8ns (typ) [2] and a high-speed data rate of 150Mbps (max), suitable for multi-channel high-speed communication applications such as I/O interfaces for SPI communication.
For 50 years, Toshiba has provided its customers with photocouplers—isolation devices that ensure insulation performance through optical coupling. Going forward, in addition to optocouplers, Toshiba will expand its lineup of high-speed four-channel digital isolators, increase the number of channels and packages, and provide high-quality isolation devices to provide reliable, real-time Data transfer is supported.
