Pix Sequence
Note1:
CBSWAP is pin 11.
Note2:
Pixel transitions must occur observing setup and hold timing about the rising edge of CLK.
Note3:
Pixel sequence will beging with Cbn at 4 x m clock periods following the falling edge of HSYNC*, when m is an integer.
6.4. Video Timing
The width of the analog horizontal sync pulses and the start and
end of color burst is automatically calculated and inserted for each
mode according to CCIR-624-4. Color burst is disabled on
appropriate scan lines. Serration and equalization pulses are
generated on appropriate scan lines. In addition, rise and fall
times of sync, and the burst envelope are internally controlled.
Video timing figures follow the text in this section.
6.4.1. Sync and burst timing
Table 3
lists the resolutions and clock rates for the various modes
of operation.
Table 4
lists the horizontal counter values for the end of horizontal
sync, start of color burst, end of color burst, front porch, back
porch, and the first active pixel for the various modes of operation.
The front porch is the interval before the next expected falling
HSYNC* when outputs are automatically blanked. The horizontal
sync width is measured between the 50% points of the falling and
rising edges of horizontal sync. The start of color burst is
measured between the 50% point of the falling edge of horizontal
sync and the first 50% point of the color burst amplitude (nominally
+20 IRE for NTSC and 150 mV for PAL-B, D, G, H, I, Nc above the
blanking level). The end of color burst is measured between the
50% point of the falling edge of horizontal sync and the last 50%
point of the color burst envelope (nom20 IRE for NTSC and
150 mV for PAL-B, D, G, H, I, Nc above the blanking level).

6.4.2. Master mode
Horizontal sync (HSYNC*) and vertical sync (VSYNC*) are
generated from internal timing and optional software bits.
HSYNC*, and VSYNC* are output following the rising edge of CLK.
The horizontal counter is incremented on every other rising edge
of CLK. After reaching the appropriate value (determined by the
mode of operation), it is reset to one, indicating the start of a new
line. The vertical counter is incremented at the start of each new
line. After reaching the appropriate value, determined by the
mode of operation, it is reset to one, indicating the start of a new
field. VSYNC* is asserted for 3 or 2.5 scan lines for 262/525 line
and 312/625 line, respectively.
