This paper describes a new circuit technique for performing clock recovery and data re-timing functions for high-speed source synchronous data communications, such as in burst-mode data transmission. The new clock recovery circuit is fully digital, non-PLL-based, and is capable of retiming the output clock with the received data within one data transition. The absence of analog filters or other analog blocks makes its area much smaller than conventional circuitry. It can also be described by any hardware description language, simulated, and synthesized into any digital process. This enables it to be ported from one technology to another and support system on a chip (SOC) designs. The design concept is demonstrated with T-Spice(R) simulations using a 0.25 µm digital CMOS technology. Static performance was evaluated in terms of supply and temperature dependent skews. The shifts in output clock due to these static conditions were within 40 pS. Also dynamic behaviours such as jitter generation and jitter transfer were evaluated. The circuit generates a jitter of 68 pS in response to a supply noise of 250 mV amplitude and 100 MHz frequency. Input data jitter transfer is within 0.1 dB up to a jitter frequency of 150 MHz.
