This component encapsulates the internal Sync Processor. Features of the Sync Processor include the following:
• Polarity detector
• Horizontal frequency counter
• Vertical frequency counter
• Low vertical frequency indicator (40.7Hz)
• Polarity controlled HSYNCO and VSYNCO outputs:
– From separate Hsync and Vsync
– From composite sync on HSYNC or SOG input pin
– From internal selectable free running Hsync and Vsync pulses
• CLAMP pulse output to the external pre-amp chip
• Internal schmitt trigger on HSYNC, VSYNC, and SOG input pins
to improve noise immunity
