Notes:
1. Room Temperature condition
2. VDRIVE-VEE at operating range.
3. The VTT value shown is for DC coupled LVPECL I/O. For AC coupled LVPECL I/O Vtt is nominally at VDD-1.3V
4. VDRIVE , VEE , and VTT at operating range.
Table 3. Recomended Operating Conditions
DC Coupled 50 Ohm Load terminated to VTerm
VDrive = (VccDrive-VeeDrive)
DOUTlogicHigh = VDrive - ((VDrive - VTerm)*0.5))
DOUTlogicLow = (DOUTlogicHigh - (ITotal*25))
Note: For proper operation DOUTlogicLow > -2V
AC Coupled 50 Ohm Load terminated to VTerm
VDrive = (VccDrive-VeeDrive)
DOUTPk-Pk = (ITotal*25)
DOUTCommonMode = VccDrive - ((ITotal*25)/2)
Note: For proper operation DOUTlogicLow > -2V
