Overview

The NB3N1200K and NB3W1200L differential clock buffers areDB1200Z and DB1200ZL compliant and are designed to work inconjunction with a PCIe compliant source clock synthesizer to providepoint−to−point clocks to multiple agents. The device is capable ofdistributing the reference clocks for Intel® QuickPath Interconnect(Intel QPI & UPI), PCIe Gen1/Gen2/Gen3/Gen4, SAS, SATA, and Intel ScalableMemory Interconnect (Intel SMI) applications. The VCO of thedevice is optimized to support 100 MHz and 133 MHz frequencyoperation. The NB3N1200K and NB3W1200L utilizepseudo−external feedback topology to achieve low input−to outputdelay variation. The NB3N1200K is configured with the HCSL buffertype, while the NB3W1200L is configured with the low−powerNMOS Push−Pull buffer type.
