The LT443D-BL Analog Black Module can generate 14 formats of HDTV analog tri-level sync, 525p/625p analog sync and NTSC/ PAL black burst signals. It consists of 3- independent systems, each with 2-outputs, to provide simultaneous multiformat black sync signals. Each system can be assigned an output format capable of independent output timing. Also, it accepts a black signal with a 10 field ID conforming to SMPTE 318M. In adjusting timing, the settable range is a frame referenced to a 54 MHz clock for 525p/625p analog sync signal and NTSC/PAL black burst signal, and a frame by 74.25 MHz or 74.25 MHz clock for HDTV analog trilevel sync signal inputs.
