High speed sync separation system and method

A synchronization separation system for accurately generating a synchronization signal from an analog video signal by using feedback, the synchronization signal indicative of when the analog video signal exhibits a synchronization level, comprising:

• a voltage generator configured to generate first and second reference voltages, the voltage generator having a first output;
• a first comparator configured to compare said analog video signal to said first reference voltage, said first comparator for generating a shift control signal;
• a voltage shift mechanism configured to receive said shift control signal and to adjust said analog video signal so that said synchronization level of said analog video signal converges toward said first reference voltage;
• a second comparator configured to compare said analog video signal to said second reference voltage, said second comparator having an output, said second comparator for generating said synchronization signal indicative of when said analog video signal exhibits said synchronization level;
• and
• a schmitt trigger disposed between said first output of said voltage generator and said output of said second comparator.
