CHANNEL 8-BIT VIDEO CONVERTER
MB40578
DESCRIPTION
Fujitsu MB40578 power ultra-high speed video converter fabricated with Fujitsu Advanced Bipolar Technology. MB40578 also adopts fully-parallel comparison technique (flash method) high speed convertion convert wide band analog signal such video signal digital signal sampling rate through Mega-samples/sec. Because such high-speed poeration, MB40578 suitable digital video applications such digital video processing with computer, radar signal processing.
