IDT / ICS 1-TO-9, 2.5V, 3.3V LVPECL/ECL FANOUT BUFFER

LOW SKEW, 1-TO-9, DIFFERENTIAL-TO-2.5, 3.3V LVPECL/ECL FANOUT BUFFER
The clock layout topology shown below is a typical termina-
tion for LVPECL outputs. The two different layouts men-
tioned are recommended only as guidelines.
FOUT and nFOUT are low impedance follower outputs that
generate ECL/LVPECL compatible outputs. Therefore, termi-
nating 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 mini-
mize signal distortion.
Figures 6A and 6B show two different
layouts which are recommended only as guidelines. Other
suitable clock layouts may exist and it would be recommended
that the board designers simulate to guarantee compatibility
across all printed circuit and clock component process varia-
tions.
