MAX9209/MAX9213
Programmable DC-Balanced
21-Bit Serializers
______________________________________________________________________________________
11
To obtain DC balance on the data channels, the paral-
lel input 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 deserializers whether the data bits are invert-
ed (Figure 11). The deserializer restores the original
state of the parallel data. The LVDS clock signal alter-
nates duty cycles of 4/9 and 5/9, which maintains DC
balance. Figure 12 shows the non-DC-balanced mode
inputs mapped to LVDS outputs.
