Leader Instruments LT443D-BL
Video Generator with Analog Black Module


The LT443D Multiformat Video Generator Main Frame can be used where multiformat digital broadcast systems are the norm. Plug-in modules enable the output of SDI signals (i.e. HDTV, SDTV) embedded audio, sync signals and genlock functions. Users can customize this signal generator as desired.

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.
