Philips Semiconductors Clock and synchronization signals of SAA7187 and SAA7188 Application note for digital video encoder Author: Leo Warmuth 1.0 INTRODUCTION The devices of the SAA7187/88 family of video encoders can be used in a variety of applications differing regarding the signal flow of timing information. Video timing is defined by clock signals, synchronization signals and blanking signals. The video encoder ICs can generate these signals by itself (master mode), or can accept them as input (slave mode). The master/slave characteristic can be chosen independently for clock and sync-signals. This application note describes the various clock and synchronization signals, their...
