Applications Information
Alternative PECL-Output Termination
Figure 4 shows alternative PECL-output termination
methods. Use Thevenin-equivalent termination when a
(VCC - 2V) termination voltage is not available. If AC-
coupling is necessary, be sure that the coupling capac-
itor is placed following the 50
or Thevenin-equivalent
DC termination.
Layout Techniques
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 MAX3890 clock and data inputs and
outputs.
Exposed Pad (EP) Package
The EP 64-pin TQFP incorporates features that provide
a very low thermal resistance path for heat removal
from the IC to a PC board. The MAX3890’s exposed
pad must be soldered directly to a ground plane with
good thermal conductance.
