The NB3W800L is a low−power 8−output differential buffer thatmeets all the performance requirements of the DB800ZLspecification. The NB3W800L is capable of distributing the referenceclocks for Intel® QuickPath Interconnect (Intel QPI & UPI), PCIeGen1/Gen2/Gen3/Gen4, SAS, SATA, and Intel Scalable Memory Interconnect(Intel SMI) applications. A fixed, internal feedback path maintains lowdrift for critical QPI applications.
