The clock layout topology shown below is a typical termination
for LVPECL outputs. The two different layouts mentioned are
recommended only as guidelines.
FOUT and nFOUT are low impedance follower outputs that gen-
erate 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

transmission lines. Matched impedance techniques should be
used to maximize operating frequency and minimize signal dis-
tortion. Figures 1A and 1B show two different layouts which are
recommended only as guidelines. Other suitable clock layouts
may exist and it would be recommended that the board design-
ers simulate to guarantee compatibility across all printed circuit
and clock component process variations.
