2-speed Miniaturized Synchro to Digital Converter or Resolver to Digital
Converter (Series MRDC /MSDC)

2-speed synchro to digital converter or resolver to digital converter (series MRDC /MSDC) are
monolithic circuits hermetically sealed by metal. They internally contain coarse/fine two way synchro to
digital converter or resolver to digital converter and error correcting logical circuit required by two speed
system.
Speed ratios of coarse/fine combination of series MRDC /MSDC product are 1:32, 1:16, 1:8, it is easy to
use. Input signals of coarse/fine two way are signals of three-wire synchcro or four-wire resolver.
