UVC 3130

      The UVC 3130 is a kind of high-speed A/D-D/A converter.It adopts VLSI circuit in CI technology,featuring the following circuits.First,it is a high-speed flash type 8-bit A/D converter.Secondly, it is a high-speed low-glitch 10-bit D/A converter which is designed as an R-2R network with switched current sources.Thirdly,it uses various auxiliary circuits,such as reference voltage sources,preamplifier,input clamping circuit,and feed-in output amplifier.The UVC 3130 has been developed for use in all applications which call for a high-speed A/D-D/A converter.For instance,the device can be used to avantage to decode television signals in Pay-TV converters or for D2-MAC converters used in direct satellite broadcast.Other promising applications can be seen in industrial electronics,e.g. in conjunction with digital signal processing.Although UVC 3130 was initialy designed as high-speed code for the video-range,it can be used with equal benefits for lower frequencies,even down to zero.
