The Sync Processor is designed to detect and process sync signals inside a digital monitor system - from separated Hsync and Vsync inputs, or from composite sync inputs such as Sync-On-Green (SOG). After detection and the necessary polarity correction and/or sync separation, the corrected sync signals are sent out.
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

Peripheral Initialization Components provide a low-level hardware approach to initialize registers of the peripheral module. They are intended for experienced users.
