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