PDR-Type Programmable Delay Lines for Video Signals


Features

  • Completely passive component, 100Ω in/out impedance.
  • Delay/Thru pass are selected with a single-winding latching relay.
  • Step accuracy is guaranteed for group delay characteristics within band-width.
  • Suitable for timing adjustment of video signals such as CAT5 extenders.
  • Step and delay time additions are being planned.
  • Sample: 1Q-2008, Production: 2Q-2008.
