The NB3N1200K and NB3W1200L differential clock buffers are DB1200Z and DB1200ZL compliant and are designed to work in conjunction with a PCIe compliant source clock synthesizer to provide point−to−point clocks to multiple agents. The device is capable of distributing the reference clocks for Intel® QuickPath Interconnect (Intel QPI & UPI), PCIe Gen1/Gen2/Gen3/Gen4, SAS, SATA, and Intel Scalable Memory Interconnect (Intel SMI) applications. The VCO of the device is optimized to support 100 MHz and 133 MHz frequency operation. The NB3N1200K and NB3W1200L utilize pseudo−external feedback topology to achieve low input−to output delay variation. The NB3N1200K is configured with the HCSL buffer type, while the NB3W1200L is configured with the low−power NMOS Push−Pull buffer type.
