RTC clock synchronization buffer driver delay chip

The NB3N1200K and NB3W1200L differential clock buffers comply with DB1200Z and DB1200ZL and are suitable for use in conjunction with PCIe-compliant source clock synthesizers to provide point-to-point clocks to multiple agents. The device is capable of distributing 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 device's VCO is optimized for operation at 100 MHz and 133 MHz. NB3N1200K and NB3W1200L use pseudo-external feedback topology to achieve low input-output delay variation. NB3N1200K is equipped with HCSL buffer, and NB3W1200L is equipped with low-power NMOS push-pull buffer.
