A Wide Band CDR for Digital Video Data Transmission

A Wide Band CDR for Digital Video Data Transmission

This paper describes a wide band CDR with a new encoding scheme for a digital video data transmission. The CDR works from 105Mbps to 1365Mbps without any external frequency references. The proposed encoding scheme uses both PECT (periodic embedded clock transition) and PECT (periodic embedded clock...

Zusammenfassung:This paper describes a wide band CDR with a new encoding scheme for a digital video data transmission. The CDR works from 105Mbps to 1365Mbps without any external frequency references. The proposed encoding scheme uses both PECT (periodic embedded clock transition) and PECT (periodic embedded clock period) scheme, and it helps the CDR's capture process. The CDR is using both digital and analog techniques. Digital block adjusts VCO frequency utilizing PECT and PECP scheme, and analog block maintains lock with small jitter. The device is fabricated on 0.35mum standard logic CMOS process
