数据中心不断增长的带宽需求需要支持 >50Gb/s/通道数据速率且功耗低的有线收发器。由于数据中心中 99% 的链路利用率<10% [1]，一种降低功耗的有前途的方法是细粒度功率门控，即在空闲时间关闭链路。为了使快速开/关功能在短数据突发情况下高效，链路需要在几纳秒内唤醒，这在高速情况下具有挑战性。之前演示过突发模式操作速度为 25Gb/s，锁定时间为 18.5ns [2]，无需电源循环。
The increasing bandwidth demand in data-centers requires wireline transceivers supporting >50Gb/s/lane data-rates with low power consumption. Because link utilization in data-centers is <10% for 99% of the links [1] a promising way to reduce power consumption is fine-grained power gating, where the link is powered off during idle time. For rapid on/off functionality to be efficient with short data bursts, the link needs to wake up within a few ns, which is challenging at high speeds. Burst mode operation was previously demonstrated at 25Gb/s with 18.5ns lock-time [2] without power cycling.
