NB3L204KMNTXG Description

Short technical summary and product information.

The NB3L204KMNTXG from ON Semiconductor is a differential 1:4 clock fanout buffer featuring High-speed Current Steering Logic (HCSL) outputs. It is capable of distributing identical clock signals up to 350 MHz.

This buffer supports a wide input signal compatibility, including differential LVPECL, LVDS, and HCSL. Single-ended signals are also accepted with an external Vth reference. The device is optimized for low phase noise, minimal propagation delay variation, and low output-to-output skew, making it suitable for demanding clock distribution applications.

Key electrical specifications include a maximum input clock frequency exceeding 350 MHz, dual supply voltage operation at 2.5V ±5% and 3.3V ±10%, and a typical propagation delay of 1 ns. Output-to-output skew is kept to a maximum of 100 ps, with additive RMS phase jitter at 80 fs.

The NB3L204KMNTXG is housed in a compact 24-QFN (4x4 mm) package with an exposed pad and is designed for surface mounting. It operates within an ambient temperature range of -40°C to +85°C.
