Abstract

This paper describes a clock and data recovery (CDR) circuit that support dual data rates of 2.7Gbps and 1.62Gbps for DisplayPort sink device. This CDR uses the half-rate linear phase detector (PD). A voltage-controlled oscillator (VCO) is proposed to change the operating frequency of half-rate clock with a "Mode" switch control. This work is implemented 0.18μm CMOS process. The device exhibits peak-to-peak jitters of 12ps and 14ps in the recovered clock with random data inputs. The power dissipation is 81mW from a 1.8V supply.
