LOW SKEW, 1-TO-4 LVCMOS-TO-3.3V LVPECL
APPLICATION INFORMATION
TERMINATION FOR LVPECL OUTPUTS
TheclocklayouttopologyshownbelowisatypicalterminationforLVPECLoutputs. Thetwodifferentlayoutsmentionedarerecommendedonlyasguidelines.
FOUT and xFOUT are low impedance follower outputs that generate ECL/LVPECL compatible outputs. Therefore, terminating resistors (DC current path to
ground) or current sources must be used for functionality. These outputs are designed to drive 50
Ωtransmissionlines. Matchedimpedancetechniquesshould
be used to maximize operating frequency and minimize signal distortion. The diagrams below show two different layouts which are recommended only as
guidelines. Other suitable clock layouts may exist. It is recommended that the board designers simulate to guarantee compatibility across all printed circuit and
clock component process variations.
