Silicon Protection Arrays Application Guide LCD and Camera Interfaces (Mobile) Considerations: ● LCD and camera interfaces in mobile devices are vulnerable to EMI from the cellular band → Frequencies between 800-3000MHz should be attenuated to prevent distortion on the display ● The pixel clocks vary depending upon the display size but the frequency will typically fall between 5-65MHz → This corresponds to data rates between 10-60Mbps and with these speeds line capacitances need to be considered → In the majority of applications line capacitances of 20-40pF will not cause signal integrity issues ● The protection schemes below for data lines Dx are only examples and will vary with the particular application Application Schematic: PCB Connector for LCD Display Baseband SP6001-04 D1 D2 IC D3 D4 Case GND Camera Module Baseband SP6001-08 D1 D2 D3 D4 IC D5 D6 D7 D8 Case GND *Packages are shown as transparent Recommended SPA Devices: SP6001-0xUTG-1 ESD Level (Contact) ±30kV Cut-off Frequency 115MHz Line Capacitance 24pF # of Channels 4/6/8 SP6002-0xUTG-1 ±30kV 100MHz 30pF 4/6 Ordering Number ©2009 Littelfuse, Inc VRWM Packaging 6V μDFN-8/12/16 6V μDFN-8/12 20
