10. Application information
In the „IEEE 100BASE-T1 EMC Test Specification for ESD suppression devices“ 1document
(further referred as OPEN Alliance 100BASE-T1 specification), the OPEN Alliance describes four
different tests to ensure compliance of ESD suppressor devices and PHYs which are compliant
according to the document “Transceiver EMC Test Specification”. The PESD2ETH100-T passes
all tests as shown on figures 7 to 18. Furthermore, it complies with the requirements mentioned in
Section 2.2. of „IEEE 100BASE-T1 EMC Test Specification for ESD suppression devices“.

Fig. 7. Application diagram
The return loss and insertion loss are evaluated using the differential S-parameters Sdd11 and
Sdd21. These measurements replace the requirement for a certain capacitance value. To ensure
symmetry, the differential to common mode rejection is evaluated using the S-parameter Ssd21.
This measurement replaces the requirement for a matching of the capacitance per line. To ensure
that the device does not degrade and changes behavior after repetitive ESD events, the S-
parameter measurements are repeated after discharging 20 times ±8 kV ESD on signal lines 1
and 2, with C = 150 pF, R = 330 Ω according to ISO 10605. Subsequently, the S-parameters are
measured again and compared to the original data. The S-parameter measurements for return and
insertion loss as well as the measurements for ESD damage are conducted on different Printed-
Circuit Boards (PCB).

ESD protection for In-vehicle networks
To predict if the ESD suppressor device would protect a PHY of a certain robustness class
(Class I (JEDEC-HBM 4 kV) and Class II (JEDEC-HBM 2 kV)), the ESD discharge current is
measured in a reference circuit according to OPEN Alliance 100BASE-T1 specification for ±4
kV and ±6 kV according to IEC 61000-4-2 with C = 150 pF and R = 330 Ω. Unlike in the OPEN
Alliance 100BASE-T1 specification of October 29 2017, the „Transceiver Simulation network“ is
implemented with 2 Ω and 50 Ω resistors.

To ensure that the ESD suppressor device is not impacting the EMC performance of the complete
module, the RF Clamping Test as defined in the OPEN Alliance specification is applied. First a
measurement at a reference power level of 25 dBm is conducted in an environment defined by
the OPEN Alliance 100BASE-T1 specification. Next, the power is increased to 33 dBm (Class I),
36 dBm (Class II), and 39 dBm (Class III). No change in the measured common mode rejection
indicates that the ESD suppressor device is not impacting the modules EMC performance.
