Figure 3 shows alternative PECL output-termination
methods. Use Thevenin-equivalent termination when a
(V
coupling is necessary, be sure that the coupling capac-
itor is placed following the 50Ω or Thevenin-equivalent
DC termination.
For best performance, use good high-frequency layout
techniques. Filter voltage supplies and keep ground
connections short. Use multiple vias where possible.
Also, use controlled-impedance transmission lines to
interface with the MAX3691 clock and data inputs and
outputs.
