Sync Slicer
TVP7000 includes a circuit that compares the input signal on Green channel to a level 150mV (typical value)
above the clamped level (sync tip). The slicing level is programmable by I2C register subaddress at 0x10. The
digital output of the composite sync slicer is available on the SOGOUT pin.
Sync Separator
The sync separator automatically extracts VSYNC and HSYNC from the sliced composite sync input supplied at
the SOG input. The G or Y input containing the composite sync must be AC coupled to the SOG input pin using
a 10-nF capacitor. Support for PC graphics, SDTV, and HDTV up to 1080p is provided.
