Parallel-Word Width
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.
Serial-Word Length
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.
