What is a clock recovery circuit?

A clock recovery circuit supplies timing to a phase locked loop (PLL), which in turn controls a clock for the recovered upstream information, as we describe shortly. From: Modern Cable Television Technology (Second Edition), 2004.

How does clock recovery work?

How does CDR work? It locks on a frequency that is retrieved from incoming data stream. To do so, it detects the data transitions and locks an VCO (Voltage Controlled Oscillator) to that frequency. This frequency is then used when generating the transmitted data bit stream.

Which type of models contains clock recovery circuits?

the phase locked loop architecture (PLL) -- the most common method of clock recovery.

What is the application of clock and data recovery CDR circuit?

The use of clock and data recovery, or CDR, provides improved clock and data synchronization and also reduces timing uncertainty. In addition, CDRs are valuable as a means of jitter mitigation for a variety of applications.
