Product data sheet
8.6 Programmable coast
8.7 Data enable
8.8 Sync separator
The maximum hum perturbation is 250 mV (p-p) at 60 Hz to have a correct SOG
functionality.
Table 5:
[1]
When the values of PRECOAST[2:0] = 0 and POSTCOAST[4:0] = 0, the coast pulse
equals the Vsync input.
When an interlaced signal is used, the regenerated coast pulse width may vary from one
frame to another of one Hsync pulse. In that case, the programmed value of
PRECOAST[2:0] needs to be increased by one compared to the expected minimum
number of Hsync coast pulses before the vertical sync signal.
This signal qualifies the active data period on the horizontal line. Pin DEO = HIGH during
the active display time and LOW during the blank time. The start of this signal can be
adjusted with bits HSYNCL[9:0] and HBACKL[9:0]. The length of this signal can be
adjusted with bits HDISPL[11:0].
The sync separator is compatible with TV, HDTV and VESA standards.
If the green video signal has composite sync on it (sync-on-green), the SOG function
allows to separate the Chsync and the active video part. The Chsync signal coming from
this SOG function is accessible through pin CSYNCO.
It is possible to extract the Hsync and the Vsync signals by using the sync separator from
this (C)Hsync signal coming from SOG or coming from the (C)Hsync input.
This function is able to get rid of the additional synchronization pulses in vertical blanking
like equalization or serration pulses.
