AOZ8533 4-Line EMI Filter with Integrated ESD Protection General Description Features The AOZ8533 is an 4-line device integrating EMI filtering with ESD protection for each line. It is designed to suppress unwanted EMI/RFI signals and provide electrostatic discharge (ESD) protection in portable electronic equipment. This state-of-the-art device utilizes AOS leading edge Trench Vertical Structure [TVS]2 ™ technology for superior clamping performance and filter attenuation over the full operating display range. The AOZ8533 has been optimized for protection of color LCD displays and CCD camera lines in cellular phones and other portable consumer electronic devices. ● 4 lines for EMI filtering and ESD protection: – Exceeds IEC 61000-4-2, level 4 (ESD) immunity test – ±30kV (air discharge) and ±24kV (contact discharge) ● Trench Vertical Structure [TVS]2 ™ based technology used to achieve excellent ESD clamping & filter performance over the full operating display range ● Cutoff frequency: 450MHz ● Filter performance: The AOZ8533 consists of four identical circuits comprised of TVS diodes for ESD protection, and a inductor–capacitor network for EMI/RFI filtering providing a cutoff frequency at 450MHz for high speed data lines. An inductor value of 17nH and a capacitance value of 16pF are used to achieve greater than -30dB attenuation at 1.0GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±30kV (air discharge) and ±24kV (contact discharge). This exceeds IEC 610004-2, level 4 ESD immunity test. ● – -30dB attenuation at 1.0GHz – -25dB attenuation from 800MHz to 5.0GHz Low operating voltage: 5.0V The AOZ8533 comes in an RoHS compliant, 1.2mm x 1.8mm, 0.4mm pitch DFN package and is rated over a -40°C to +85°C ambient temperature range. ● Capacitance stability over wide range of voltages and temperatures ● DFN package: 1.2mm x 1.8mm, 0.4mm pitch ● Pb-Free device Applications ● EMI filtering and ESD protection for data lines ● LCD displays, camera interface, I/O interface ● Portable handheld devices, cell phones, PDA phones Typical Application D0 D1 D2 D3 17nH CH1 16pF 16pF 17nH CH2 16pF 16pF LCD/Camera Module 17nH CH3 16pF 16pF 17nH CH4 16pF 16pF Figure 1.
