WDA-1001

Word Clock Distribution Amplifier

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.

FEATURES

  • Fans out up to 8 Word Clock signals
  • DC Coupled all the way through
  • Wide range of amplitudes and frequencies
  • Works with both AC-coupled and TTL/CMOS type of signals
  • SDIF-2 Word Clock compliant
  • Built-in basic input signal probing with programmable thresholds
  • Adjustable output levels
