Manufacturer:POWER Description:cal sync pulse; a burst gate or back porch clamp pulse; and an odd/even output. The odd/even output level identifies which video field of an interlaced video source is present at the input. The outputs from the LM1881 can be used to gen-lock video camera/VTR signals with graphics sources, provide identification of video fields for memory storage, recover suppressed or contaminated sync signals, and pro- vide timing references for the extraction of coded or uncoded data on specific video scan lines. To better understand the LM1881 timing information and the type of signals that are used, refer to Figure 1(a-e) which shows a portion of the composite video signal from the end of one field through the beginning of the next field. |
