Description

General part information

NB3N1900K Series

The NB3N1900K differential clock buffers are designed to work inconjunction with a PCIe compliant source clock synthesizer to providepoint−to−point clocks to multiple agents. The device is capable ofdistributing the reference clocks for Intel® QuickPath Interconnect(Intel QPI & UPI), PCIe Gen1, Gen2, Gen3, Gen4. The NB3N1900K internal PLL isoptimized to support 100 MHz and 133 MHz frequency operation.The NB3N1900K supports HCSL output levels.
