1.
All LVTTL input pins have pull-up resistors.
2.
See section 6 for dynamic power consumption calcualtion.
3.
Refer to Figures 7 and 8 for termination resistor.
4.
Refer to Figures 9 and 10 for termination resistor.
5.
Maximum capacitive load is 12 pF.
These values in Table 20 are valid at the output of the source termination pack, as shown in sections 3.2
and 3.3, with a 100
differential load only. The V
OH
levels are 200mV below LVPECL levels and are
compatible with devices tolerant of lower common-mode ranges. The above table summarizes the DC
output specifications of LVPECL.
