Detailed Description
The MAX9217 DC-balanced serializer operates at a
parallel clock frequency of 3MHz to 35MHz, 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 (Table 1). Control inputs are mapped to 19 bits
and encoded with 1 overhead bit, EN0, also resulting in
a 20-bit serial word. Encoding reduces EMI and main-
tains DC balance across the serial cable. Two transition
words, which contain a unique bit sequence, are insert-
ed 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 (Table 2). At the deserializer,
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.
