NB3N1900KMNG Description

Short technical summary and product information.

The NB3N1900KMNG from On Semiconductor is a differential clock buffer capable of distributing reference clocks for various applications, including PCIe and Intel QPI/UPI. It operates with a 1:19 fanout ratio and supports HCSL output levels.

This device features a fixed feedback path for low input-to-output delay, with a variation of less than 50 ps. It offers selectable PLL bandwidth and is compatible with spread spectrum clocking for reduced EMI. The buffer supports 100 MHz and 133 MHz operation, meeting requirements for PCIe Gen2/Gen3/Gen4 and Intel QPI & UPI phase jitter specifications.

Key electrical characteristics include a cycle-to-cycle jitter of less than 50 ps and an output-to-output skew of less than 65 ps. The operating voltage range is 3.135V to 3.465V, with an operating temperature range of -10°C to 70°C.

The NB3N1900KMNG is available in a 72-QFN (10x10) package and is designed for surface mounting.
