FEMTOCLOCKSCRYSTAL-TO-LVPECL
312.5MHZ FREQUENCY MARGINING SYNTHESIZER
PRELIMINARY
TERMINATION FOR 2.5V LVPECL OUTPUT
Figure 5A and Figure 5B show examples of termination for
2.5V LVPECL driver. These terminations are equivalent to
terminating 50
Ω to V
CC - 2V. For VCC = 2.5V, the VCC - 2V is
very close to ground level. The R3 in Figure 4B can be
eliminated and the termination is shown in Figure 4C.
