Abstract :
This paper presents a 650Mb/s-to-8Gb/s referenceless CDR with an automatic tracking of data-rate. With a DLL-based frequency acquisition, the presented dual-loop CDR shows the highest performance in lock-range, power consumption, and size compared with previously reported continuous-rate CDRs.
