1 Description
The V6153 and V6154 areapairofdistribution amplifiersforSDI Video. Bothcan process both
StandardDefinition (SD)and HighDefinition (HD)video,butthe V6153haseightoutputswhile
theV6154hassixteenoutputs.
The V6153 isasinglewidthmodule,whilethe V6154 isadoublewidthmodule, requiring apair

Bothunitsarepart ofthe V1600 rangeofinterfacemodulesand arebuilt on a3U high Eurocard
whichcan befitted intoaV1606 3Uchassisalong withanyothercardsfromtherange.Unlike
manymodulesinthe range the V6153 and V6154 cannotbe used intheV16011U Chassis.
ThisisduetothetechnicalrequirementsforHD signalbandwidths.
