A novel equal-slope baud rate clock and data recovery (CDR) algorithm is proposed. By positioning the locked point on pulse response where pre-cursor slope and main-cursor slope are equal, an optimized eye-opening is achieved with enhanced eye height, eye width and timing margin. The algorith...
A four-level pulse amplitude modulation (PAM-4) baud-rate clock and data recovery (CDR) is proposed for a power-efficient receiver. The baud-rate CDR reduces the burden of multi-phase clock generation and distribution, thus reducing the power consumption of clocking circuits. A pattern-based ...
In an example, a clock data recovery (CDR) circuit for a receiver includes a timing error detector circuit, a loop filter, and a phase interpolator. The timing error detector circuit is coupled to receive, at a baud-rate, data samples and error samples for symbols received by the receiver...

The baud rate generator furnishes the bit period clock, or baud rate clock, for both the receiver and the transmitter. The baud rate clock is implemented by distributing the base clock UART_REF_CLK and a single cycle clock enable to achieve the effect of
A sub-baud-rate CDR that can recover clock and data using only a quarter-rate clock is presented. Four data bits are recovered in each clock cycle using eight samplers and a current integrator. Four of the eight samplers used for data recovery are re-used for phase detection. Fabricated in...
