When interfacing with differential PECL input levels, it is
important to attenuate the signal while still maintaining
50Ω termination (Figure 7). AC-coupling is also
required to maintain the input common-mode level.
For best performance, use good high-frequency layout
techniques. Filter voltage supplies, keep ground con-
nections short, and use multiple vias where possible.
Use controlled impedance transmission lines to inter-
face with the MAX3880 high-speed inputs and outputs.
Power-supply decoupling should be placed as close to
V
isolate the input signals from the output signals.
