Datasheet

CAD Model

Overview

The NB3N1900K differential clock buffers are designed to work inconjunction with a PCIe compliant source clock synthesizer to providepoint鈭抰o鈭抪oint clocks to multiple agents. The device is capable ofdistributing the reference clocks for Intel庐 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.
