摘要

源同步链路通常用于服务器系统中的多通道高速串行应用程序,例如连接CPU到CPU、到内存或到桥接芯片,因为它们固有地跟踪相关抖动[1]。提出了一种由22个数据通道和1个时钟通道组成的低功耗紧凑差分源同步接收机PHY。该接收器,加上相应的发射器和阻抗校准宏,支持4.8至6.4Gb/s的多种差分和接地端链路标准,如英特尔QPI 1.0和IBM专有内存链路。

A 4.5mW/Gb/s 6.4Gb/s 22+1-lane source-synchronous link rx core with optional cleanup PLL in 65nm CMOS
Source synchronous links are often used in server systems for multi-lane high-speed serial applications such as connecting CPU to CPU, to memory, or to bridge chips due to their inherent tracking of correlated jitter [1]. This paper presents a low-power compact differential source synchronous receiver PHY comprised of 22 data lanes and 1 clock lane. This receiver, plus a corresponding transmitter and impedance calibration macro, support multiple differential and ground terminated link standards at 4.8 to 6.4Gb/s, such as Intel QPI 1.0 and IBM proprietary memory links.
