VL6524/VS6524
Data synchronization methods

8.2
VSYNC and HSYNC
The VL6524/VS6524 can provide two programmable hardware synchronization signals:
VSYNC and HSYNC. The position of these signals within the output frame can be
programmed by the user or an automatic setting can be used where the signals track the
active video portion of the output frame regardless of its size.
8.2.1
Horizontal synchronization signal (HSYNC)
The HSYNC signal is controlled by the bHSyncSetupregister (
Table 29
) The following
options are available:
enable/disable
select polarity
all lines or active lines only
manual or automatic
●

●
In automatic mode the HSYNC signal envelops all the active video data on every line in the
output frame regardless of the programmed image size. Line codes (if selected) fall outside
the HSYNC envelope as shown in
Figure 15
.
Figure 15.
HSYNC timing example
If manual mode is selected then the pixel positions for HSYNC rising edge and falling edge
are programmable. The pixel position for the rising edge of HSYNC is programmed in the
bHsyncRisingH bHsyncRisingLregisters. The pixel position for the falling edge of HSYNC
is programmed in the bHsyncFallingHand bHsyncFallingLregisters (
Table 29
).
