Can you tell me why you would want to use the x2 series termination with a video amplifier? I don't think you mentioned anything more than matching line/termination impedances which means as usual your post is misinformational and/or incomplete...Your statement:"Without the extra gain and resistor you have a sever mismatch which causes no end of problems."

Keep it up guys. Soon I'll be able to extract a filterable commonality ;-) ...Jim Thompson -- | James E.Thompson, P.E. | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona Voice:(480)460-2350 | | | E-mail Address at Website Fax:(480)460-2142 | Brass Rat | | http://www.analog-innovations.com | 1962 | America: Land of the Free, Because of the Brave
