LOW SKEW, 1-TO-5

2.5V/3.3V DIFFERENTIAL-TO-LVPECL/ECL FANOUT BUFFER

TERMINATION FOR 2.5V LVPECL OUTPUT

Figure 4A and Figure 4B show examples of termination for 2.5V

LVPECL driver. These terminations are equivalent to terminat-

ing 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.
