Figure 13. DC-Coupled Link, Non-DC-Balanced Mode
Bit errors experienced with DC-coupling can be elimi-
nated by increasing the receiver common-mode volt-
age range by 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 an offset volt-

age of 1.25V, 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
DC-coupled link (2.4V - 1.425V = 0.975V and 1.075V -
0V = 1.075V). Figure 13 shows the DC-coupled link,
non-DC-balanced mode.
