    This work reports a low power implementation of a 60Gb/s NRZ optical receiver (RX) in 14nm bulk CMOS finFET featuring a first-order digital CDR with high jitter tolerance (JTOL). The design includes a single phase-rotator (PR) with low complexity control logic suitable for high-speed applications. Multi-phase clock signals that drive data/edge slicers are created by an open loop-quadrature clock generator. The circuit, characterized in an 850nm VCSEL based optical link, recovers PRBS7 data (BER<10E-12) at 60Gb/s. At this data rate, the CDR achieves +/- 600ppm frequency tracking range. The measured sinusoidal JTOL indicates a corner frequency of about 80MHz, with high frequency JTOL of 0.16UIpp at -5dBm optical modulation amplitude (OMA). The RX energy efficiency is 1.9pJ/bit
