The internal logic of the device is designed to improve EMI performance, making it compliant with stringent automotive and industrial EMI requirements.

The working principle of the NB6L239MN is based on the PLL architecture. It consists of a voltage-controlled oscillator (VCO) and a phase-locked loop whose feedback loop is used to generate a stable clock signal. The VCO is used to generate a clock signal of the desired frequency. The input frequency is compared to the VCO output frequency and any difference is detected and fed back to the VCO, thus providing the PLL lock. The closed loop of its feedback then adjusts the VCO output frequency to match the input frequency, thus providing a stable clock output with low jitter sensitivity.

In summary, the NB6L239MN is an ultra-low jitter clock generator with PLL that is specifically designed for automotive and industrial grade applications. It integrates the latest in digital clock generation and jitter attenuation technology and provides improved jitter performance and EMI performance. It is capable of generating stable output clock frequencies even with wide dynamic input frequency selections, and can provide PLL lock frequencies up to 200 MHz. Its architecture is based on an all-digital VCO and PLL and is ideal for applications that require low jitter performance and robust EMI performance.
