The clock regeneration is realized by an analog approach, while the frame recovery is implemented using digital techniques. The total analog path, containing a novel ECL-CMOS, the clock regeneration and CMOS-ECL converters, is designed to keep the maximum peak clock jitter lower than 300 ps and the rms jitter below 70 ps.
