LTM2884-Slide4

The LTM2884 is a very robust solution and minimizes EMI, so it is not easily disturbed and does not disturb neighboring components. The LTM2884 provides continuous, uninterrupted communication through common mode transient events greater than 30kV/μs, without introducing any priority data jitter or data corruption. The system also includes data refresh and error checking for truly robust digital communications. Enhanced ESD protection allows the LTM2884 to withstand up to ±15kV human body model on the USB transceiver interface pins to local supplies and ±15kV through the isolation barrier to supplies without latch-up or damage. The LTM2884 has been independently evaluated and successfully passed the RF and magnetic field immunity testing requirements per European Standard EN 55024, in accordance with the following test standards and associated limits. Design and layout techniques allow the LTM2884 to minimize EMI as shown in the graph. Users can see that the LTM2884 demo board, the DC1789A in blue, is well below the CISPR22 class B limit in red.
