2-lines (one differential channel) common-mode filter with integrated ESD protection up to 15 kV contact discharge, exceeding IEC 61000-4-2, level 4. The device can eliminate efficiently common-mode noise from USB 2.0 and other high-speed interfaces with differential lines. IP3319CX6 attenuates significantly common-mode noise above 800 MHz while differential-mode signal extends out to more than 1 GHz before reaching the -3 dB point. IP3319CX6 is designed to protect sensitive I/Os, such as USB 2.0, Ethernet, Digital Video Interface (DVI) and Low-Voltage Differential Signaling (LVDS) interfaces from destruction by ElectroStatic Discharge (ESD). IP3319CX6 is a combination of an integrated copper-coils common-mode filter and a monolithic silicon technology-based ESD protection. It integrates two ultra-low capacitance rail-to-rail diodes plus a separated protection diode in a 0.4 mm pitch Wafer-Level Chip-Size Package (WLCSP). Due to the rail-to-rail concept, the protection is working independently from availability of a supply voltage.
