The WDA-1001 is a word clock distribution amplifier that provides eight outputs and supports a wide range of clock frequencies and amplitudes. It can fan out AC coupled as well as TTL/CMOS types of signals because the amplifier maintains an end-to-end DC transparency. A passive loop-through input is provided to ease distribution of more than eight Word Clock signals by daisy chaining other WDA-1001 cards. Alarms can be enabled to monitor input signal presence and/or overload conditions with user programmable thresholds.
