spread-spectrum PLL locks immediately after (see
Figure 16). If the spread-spectrum PLL loses lock, it
locks again with only one PLL lock delay (see Figure 17).
Bit errors experienced with DC-coupling (Figure 18)
can be eliminated by increasing the receiver common-
mode voltage range through AC-coupling. AC-coupling

increases the common-mode voltage range of an LVDS
receiver to nearly the voltage rating of the capacitor. The
typical LVDS driver output is 350mV centered on a 1.25V
offset voltage, making single-ended output voltages of
1.425V and 1.075V. An LVDS receiver accepts signals
from 0V to 2.4V, allowing approximately ±1V common-
mode difference between the driver and receiver on a
