The unitsareavailableinthreeresolutions,or levels,ofGray Scaleoutput.The HDG-0405 acceptsfourbits(16levels)of digitalinput;theHDG-0605 has sixbits(64levels);and the HDG-O805 isan eight-bit(256levels)device, Allversionshavecompletecompositecontrols,includingself-con- tained,digitally-controlledsyncand blanking;and a reference whitecontrolinputtohelpassurecompatibilitywithEIA StandardS . RS-l70,RS-330,and RS-343-A.Theirperformanceisenhanced evenmore witha 10% brightinputcapability.

~s thefootnotetothetablepointsout,theactualfull-scale (- 637.5m V) outputof theHDG unitsisdifferentfrom the ideal-643m V outputshown inthecompositewaveform. The tWo aredifferentbecauseAnalog Devicesuses2.5mV for weightingtheLSB duringcalibrationoftheconverter.The . disparitydoesnotcauseany problemsinusingthedevice,since bOththeidealvalueand theactualvaluearewellwithinthe tolerancesoftheoutputand theRS-343 standard.
