SmartNICs

SmartNICs (smart network interface cards) are an essential piece of today’s data center infrastructure, offloading the workload of the host processor and enabling expanded services. Reference clocks are a critical component in SmartNICs. These clocks must be resilient under airflow, heat, and vibration. SiTime MEMS timing solutions are built to reliably operate in the tight, hot environments of BBUs and DUs, while consuming less space and power.

SiTime differential oscillators offer low jitter and best-in-class PSNR to improve signal integrity. When IEEE 1588 clock recovery is needed, SiTime Elite Platform® Super-TCXOs® for Data Center Infrastructure are ideal – offering OCXO-grade frequency slope in a TCXO form factor that is small enough to fit on the back of a card.
