Figure 8. Sync Processing Block Diagram
Sync Processing
The inputs of the sync processing section of the AD9981 are
combinations of digital Hsyncs and Vsyncs, analog sync-on-
green, or sync-on-Y signals, and an optional external Coast
signal. From these signals it generates a precise, jitter-free (9%
or less at 95 MHz) clock from its PLL; an odd-/even-field signal;
Hsync and Vsync out signals; a count of Hsyncs per Vsync; and
a programmable SOG output. The main sync processing blocks
are the sync slicer, sync separator, Hsync filter, Hsync
regenerator, Vsync filter, and Coast generator.
The sync slicer extracts the sync signal from the green graphics
or luminance video signal that is connected to the SOGIN input
and outputs a digital composite sync. The sync separator’s task
is to extract Vsync from the composite sync signal, which can
come from either the sync slicer or the Hsync input. The Hsync
filter is used to eliminate any extraneous pulses from the Hsync
or SOGIN inputs, outputting a clean, low-jitter signal that is
appropriate for mode detection and clock generation. The
Hsync regenerator is used to recreate a clean, although not low
jitter, Hsync signal that can be used for mode detection and
counting Hsyncs per Vsync. The Vsync filter is used to elimi-
nate spurious Vsyncs, maintain a stable timing relationship
between the Vsync and Hsync output signals, and generate the
odd/even field output. The Coast generator creates a robust
Coast signal that allows the PLL to maintain its frequency in the
absence of Hsync pulses.
Sync Slicer
The purpose of the sync slicer is to extract the sync signal from
the green graphics or luminance video signal that is connected
to the SOGIN input. The sync signal is extracted in a two step
process. First, the SOG input is clamped to its negative peak,
(typically 0.3 V below the black level). Next, the signal goes to a
comparator with a variable trigger level (set by Register 0x1D,
Bits [7:3]), but nominally 0.128 V above the clamped level. The
sync slicer output is a digital composite sync signal containing
both Hsync and Vsync information (see Figure 9).
