MAX9210/MAX9214/MAX9220/MAX9222
Programmable DC-Balance
21-Bit Deserializers
_______________________________________________________________________________________
9
To obtain DC balance on the data channels, the serial-
izer parallel data is inverted or not inverted, depending
on the sign of the digital sum at the word boundary.
Two complementary bits are appended to each group
of 7 parallel input data bits to indicate to the MAX9210/
MAX9214/MAX9220/MAX9222 deserializers whether
the data bits are inverted (see Figures 9 and 10). The
deserializer restores the original state of the parallel
data. The LVDS clock signal alternates duty cycles of
4/9 and 5/9, which maintain DC balance.
AC-Coupling Benefits
Bit errors experienced with DC-coupling can be elimi-
nated by increasing the receiver common-mode voltage
range by AC-coupling. AC-coupling increases the com-
mon-mode voltage range of an LVDS receiver to nearly
