DC-Balanced LVDS Serializer

Detailed Description
The MAX9247 DC-balanced serializer operates at a
2.5MHz-to-42MHz parallel clock frequency, serializing
18 bits of parallel video data RGB_IN[17:0] when the
data-enable input DE_IN is high, or 9 bits of parallel
control data CNTL_IN[8:0] when DE_IN is low. The
RGB video input data are encoded using 2 overhead
bits, EN0 and EN1, resulting in a serial word length of
20 bits (see Table 1). Control inputs are mapped to 19
bits and encoded with 1 overhead bit, EN0, also result-
ing in a 20-bit serial word. Encoding reduces EMI and
maintains DC balance across the serial cable. Two
transition words, which contain a unique bit sequence,
are inserted at the transition boundaries of video-to-
control and control-to-video phases.
Control data inputs C0 to C4 are mapped to 3 bits each
in the serial control word (see Table 2). At the deserial-
izer, 2 or 3 bits at the same state determine the state of
the recovered bit, providing single-bit-error tolerance
for C0 to C4. Control data that may be visible if an error
occurs, such as VSYNC and HSYNC, can be connect-
ed to these inputs. Control data inputs C5 to C8 are
mapped to 1 bit each.
