Abstract
A clock and data recovery (CDR) circuit receives a data signal and generates a clock signal and a recovered data signal. The CDR circuit includes a clock-recovery circuit (CRC), a sampling phase-recovery circuit (PRC), an analog-to-digital converter (ADC), and a data-recovery circuit (DRC). The CRC receives the data signal and generates an intermediate clock signal. The PRC receives the intermediate clock signal, a sampled data signal and the recovered data signal, and generates the clock signal. The ADC receives the data signal and generates the sampled data signal. The DRC receives the sampled data signal and generates the recovered data signal. The clock signal is phase and frequency synchronized with the data signal.
