Overview
The NB3N502DR2G is a PLL (Phase-Locked Loop) clock multiplier device produced by onsemi. This component is designed to generate a low jitter, TTL/CMOS level output clock that is a precise multiple of the external input reference clock signal. It serves as a cost-efficient replacement for traditional crystal oscillators in electronic systems. The device can accept either a standard fundamental mode crystal or an external reference clock signal and produce an output clock up to 190 MHz with a 50% duty cycle.
