NB3N1900K
NB3N1900K is 3.3V 100/133MHz Differential 1:19 HCSL Clock ZDB/Fanout Buffer manufactured by onsemi.
3.3V 100/133 MHz Differential 1:19 HCSL Clock ZDB/Fanout Buffer for PCIe[
Description The NB3N1900K differential clock buffers are designed to work in conjunction with a PCIe pliant source clock synthesizer to provide point- to- point clocks to multiple agents. The device is capable of distributing the reference clocks for Intel® Quick Path Interconnect (Intel QPI), PCIe Gen1, Gen2, Gen3. The NB3N1900K internal PLL is optimized to support 100 MHz and 133 MHz frequency operation. The NB3N1900K supports HCSL output levels.
