2.15.2 ESD immunity test of TOBY-L2 and MPCI-L2 series reference designs
Although EMC / ESD certification is required for customized devices integrating TOBY-L2 and MPCI-L2 series
modules for R&TTED and European Conformance CE mark, EMC certification (including ESD immunity) has been
successfully performed on TOBY-L2 and MPCI-L2 series modules reference design according to European Norms
summarized in Table 45.
The EMC / ESD approved u-blox reference designs consist of a TOBY-L2 and MPCI-L2 series module installed
onto a motherboard which provides supply interface, SIM card and communication port. External LTE/3G/2G
antennas are connected to the provided connectors.
Since external antennas are used, the antenna port can be separated from the enclosure port. The reference
design is not enclosed in a box so that the enclosure port is not identified with physical surfaces. Therefore,
some test cases cannot be applied. Only the antenna port is identified as accessible for direct ESD exposure.
u-blox TOBY-L2 and MPCI-L2 series reference designs ESD immunity test results will be described in a
successive release of the document.
2.15.3 ESD application circuits
The application circuits described in this section are recommended and should be implemented in the device
integrating TOBY-L2 and MPCI-L2 series modules, according to the application device classification (see ETSI EN
301 489-1 [21]), to satisfy the requirements for ESD immunity test summarized in Table 45.
ESD application circuits will be described in a successive release of the document.
