NB3N1900K: 3.3 V 100/133 MHz Differential 1:19 HCSL Clock ZDB/Fanout Buffer for PCIe

Description: The NB3N1900K differential clock buffers are desig...
  • The NB3N1900K differential clock buffers 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. The NB3N1900K internal PLL is optimized to support 100 MHz and 133 MHz frequency operation. The NB3N1900K supports HCSL output levels.
