Specifications
Matrox Solios eA/XA acquisition section 77
PSGs
Matrox Solios eA/XA Quad features four programmable synchronization
generators (PSGs), Matrox Solios eA/XA Dual features two, whereas Matrox Solios
eA/XA Single features one. The PSGs are responsible for managing all input and
output video timing, synchronization, trigger, timer, and user signals. The PSGs
on Matrox Solios eA/XA allow the board to adapt to many video standards. Each
PSG allows for independent acquisition from a video source. Therefore, Matrox
Solios eA/XA allows acquisition from up to four independent video sources,
depending on the board.
The phase-locked loop
The high-performance, low-jitter phase-locked loop (PLL) uses frequency
synthesis techniques to generate the clock signal in slave mode.
As a reference, the PLL uses the composite or horizontal video synchronization
signal supplied by the video source (line-locked mode).
Since the signal from the video source is used as a reference, the PLL can produce
a clock signal that is a multiple of it. If the video source supplies a clock signal
within the input range of the A/D converters, the PLL is bypassed to avoid adding
jitter to the supplied clock.
