A Phase Interpolator CDR with Low-Voltage CML Circuits
摘要
In this paper, a phase interpolator clock and data recovery (CDR) with low-voltage current mode logic (CML) latched, buffers, and muxes is presented. Because of using the CML circuits, the CDR can operate in a low supply voltage. And the original swing of the differential inputs and outputs is less than that of the CMOS logic. The power supply voltage is 1.2 V, and the static current consumption is about 20 mA. In this phase interpolator CDR, the charge pump and loop filter are replaced by a digital filter. And this structure offers the benefits of increased system stability and faster acquisition.
