silicon protection arrays ?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 (t p =8/20 s) i/o capacitance # of channels v rwm 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
