The document discusses providing precise synchronization to open compute servers through the OSA 5400 TimeCard, a PCIe card that injects accurate timing. It notes the growing need for synchronization in applications like 5G networks and data centers. The TimeCard supports PTP, NTP, SyncE and GNSS with various oscillator options. It can precisely synchronize a wide range of applications and is a cost-effective way to make open servers time-aware through an easy to integrate module.
