FOR
3.3V LVPECL O
UTPUT
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 following outputs that gen-
erate ECL/LVPECL compatible outputs. Therefore, terminating re-
sistors (DC current path to ground) or current sources must be
used for functionality. These outputs are designed to drive 50Ω
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 designers
simulate to guarantee compatibility across all printed circuit and
clock component process variations.
FOR
2.5V LVPECL O
UTPUT
Figure 2A
and
Figure 2B
show examples of termination for 2.5V
LVPECL driver. These terminations are equivalent to terminating 50Ω
to V
CC
- 2V. For V
CC
= 2.5V, the V
CC
- 2V is very close to ground level.
The R3 in Figure 2B can be eliminated and the termination is shown
in
Figure 2C.
