The performance of the anti-jitter circuit with enhanced feedback ('EF-AJC')

The anti-jitter circuit (AJC) is a wide-bandwidth feedforward jitter suppression device realizable as an IC cell. An additional AC-coupled high-gain 'enhanced-feedback' loop typically gives a hundred times reduction in the lowest AJC suppression frequency. It also gives a considerably improved suppression capability and a substantial reduction of internal noise out to about one twentieth of the carrier frequency.
