ON Semiconductor NCID9211 Ceramic Digital Isolator
Robust digital isolator supports high-speed communication up to 100Mbits/s
The NCID9211 from ON Semiconductor is high-speed, dual-channel isolator which enables digital signals to be transferred between systems without exposing them to conducting ground loops or hazardous voltages.
Supporting full-duplex, bi-directional communication, the NCID9211 is based on ON Semiconductor’s patented galvanic isolation technology, which uses an off-chip capacitor. It is the only digital isolator to provide insulation reliability which matches that of an optocoupler.
The ON Semiconductor NCID9211’s thick ceramic substrate yields capacitors which are around 25 times thicker than thin-film on-chip capacitors and coreless transformers. This gives a Distance Through Insulation (DTI) greater than 0.5mm - similar to the typical DTI of an optocoupler. This DTI guarantees working voltages up to 1,500V without relying on the dielectric insulation material.
At the same time, the NCID9211 ceramic digital isolator provides outstanding electrical performance, including a maximum propagation delay of 25ns and maximum pulse distortion of 10ns. This means it supports a data transfer rate up to 100Mbits/s.
