GS4981

GS1881, GS4881, GS4981 Monolithic Video Sync Separators Features noise tolerant odd/even flag, back porch and horizontal sync pulse fast recovery from impulse noise excellent temperature stability 0.5V to 4Vpp input signal amplitude with 5V supply well-controlled clamp discharge current and slicing level programmable horizontal scan rate (up to 130kHz) composite, vertical, back porch, odd/even (GS1881, GS4881), horizontal (GS4981) outputs predictable vertical output pulse width with default trigger for non-standard video signals Pb-free and Green 5V to 12V supply voltage range pin compatible with LM1881 sync separator Application Selection Chart Application Direct LM1881 Replacement with Improved Performance New Applications Substitution for LM1881 New Applications Requiring Horizontal Sync Output Choose Device: GS1881 GS4881 GS4981 Description The GS1881, GS4881 and GS4981 are general purpose sync separators for use in a wide variety of video applications. The devices extract the timing information from composite video signals with scan rates from 15 to 130kHz. The GS1881 is a drop-in replacement for the industry standard LM1881 with much improved performance. The device generates composite sync, vertical sync, back porch and odd/even field signals. The GS4881 is identical to the GS1881 but features a noise immune back porch pulse which maintains a constant H rate during the vertical interval. The GS4981 is identical to the GS4881, except that it pr...
