©2009 Littelfuse, Inc 17 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: Recommended SPA Devices: Ordering Number ESD Level (Contact) Lightning (tP=8/20μs) I/O Capacitance # of Channels VRWM Packaging SP1004-04VTG ±8kV 2A 5pF 4 6V SOT953 SP1002-01JTG ±8kV 2A 5pF 1 6V SC70-3 SP1002-02JTG ±8kV 2A 5pF 2 6V SC70-5 Video ADC Outside World Y Case GND Video Port C Chrominance Luminance Composite IC Video RF Coaxial Case GND SP1004
