NB3N1200K: 3.3 V 100/133 MHz Differential 1:12 HCSL Clock ZDB/Fanout Buffer for PCle
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), PCIe Gen1/Gen2/Gen3, 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.
