Recently, progress has been made to move more control electronics from RT to CT, reducing interconnect overhead. The next step towards minimal interconnect is a direct wireline interface between RT and CT. This work presents a fullrate 10 Gb/s clockanddata recovery circuit for a high speed serial link receiver operating at CT.A novel phase detector is utilized to reduce power consumption by removing the need for both a pulse generator at the input and, a buffer between the phase detector and voltage controlled oscillator. Additionally, a digital delaylocked loop is added to improve the retiming margin, achieving higher jitter tolerance. Implemented in 40nm CMOS, postlayout simulation shows a core power consumption of 3.89 mW from a 1.1V supply at 10 Gb/s, producing an rmsjitter of 84 fs and an estimated jitter toleranceof 1.1 UIpp at 10 MHz.
