NB3W1900L: 3.3 V 100/133 MHz Differential 1:19 HCSL-Compatible Push‐Pull Clock ZDB/Fanout Buffer for PCIe Gen1/Gen2/Gen3/Gen4.

Description: The NB3W1900L differential clock buffers are desig...
  • The NB3W1900L 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 NB3W1900L internal PLL is optimized to support 100MHz and 133 MHz frequency operation. The NB3W1900L is developed with the low-power NMOS Push-Pull buffer type.
