Silicon Protection Arrays Application Guide Analog Video Considerations: ● Analog video ports typically have signals that swing above and below GND (i.e. ±2V) → A bidirectional protection device should be used as these devices will not clip the analog signal ● S-Video, Composite, and RF/Coaxial are a few of the common low-speed analog video signals in use today →Typical bus speeds will not exceed 5MHz so capacitance is not much of a concern → Protection of the three are shown below (Y, C, Video, and RF) Application Schematic: Video Port Video ADC Y Luminance C Chrominance Composite Video Outside World RF Coaxial IC SP1004 Case GND Case GND Recommended SPA Devices: SP1004-04VTG ESD Level (Contact) ±8kV Lightning (tP=8/20μs) 2A I/O Capacitance 5pF # of Channels 4 SP1002-01JTG ±8kV 2A 5pF SP1002-02JTG ±8kV 2A 5pF Ordering Number ©2009 Littelfuse, Inc VRWM Packaging 6V SOT953 1 6V SC70-3 2 6V SC70-5 17
