1. These values are valid at the output of the source termination pack as shown above with 100-ohm differential load only (see Figure 19).

The VOH levels are 200mV below the standard LVPECL levels and are compatible with devices tolerant of the lower common mode ranges.

2. Valid for 0.2 ≤ VCM ≤ 1.8V
