Tables 1 and 2 show the default power-up values for
the MAX9257/MAX9258 registers. Tables 3 and 4 show
the input and output supply references.
The parallel-word width is made up of the video data
bits, HSYNC, and VSYNC. The video data bits are pro-
grammable from 8 to 16 depending on the pixel clock,
serial-data rate, and parity. Table 16 shows the parallel-
word width.
The serial-word length is made up of the parallel-word
width, encoding bits, and parity bits. Tables 5–9 show
the serial video format and serial-word lengths without
parity. Tables 10–13 show with parity bits included.
Serial LVDS data is transmitted least significant bit (LSB)
to most significant bit (MSB) as shown in Tables 5
through 13. The ECU at startup can program the parallel
