TEST

IEC 61000-4-2

The IEC 61000-4-2 standard covers ESD testing and

performance of finished equipment. It does not spe-

cifically refer to integrated circuits. The major difference

between tests done using the HBM and IEC 61000-4-2

is higher peak current in IEC 61000-4-2, because series

resistance is lower in the IEC 61000-4-2 model. Hence,

the ESD withstand voltage measured to IEC 61000-4-2

is generally lower than that measured using the HBM.

Figure 6 shows the IEC 61000-4-2 model and Figure 7

shows the current waveform for the Q8kV, IEC 61000-4-2,

Level 4, ESD Contact-Discharge Method.

Layout

Hi-Speed USB requires careful PCB layout with 45I

single-ended/90I differential controlled-impedance

matched traces of equal lengths. Ensure that bypass

capacitors are as close to the device as possible. Use

large ground planes where possible.
