H/V-Synchronization
Slicer and acquisition interface need many signals synchronized to the incoming CVBS
(e.g. line number, field or line start). Therefore a sync slicing level is calculated and the
sync signal is sliced from the filtered digital CVBS signal. Using digital integration vertical
and horizontal sync pulses are separated. The horizontal pulses are fed into a digital H-
PLL which has flywheel functionality. The H-PLL includes a counter which is used to
generate all the necessary horizontal control signals. The vertical sync is used to
synchronize the line counter from which the vertical control signals are derived.
The synchronization block includes a watchdog which keeps control of the actual lock
condition of the H-PLL.The watchdog can produce an interrupt (CC_IR) if
synchronization has been lost. It could therefore be an indication for a channel change
or missing input signal.
Note: This H/V synchronization for the slicer 2 uses the same algorithms as described
above.
