Clock/timing devices play a crucial role in most digital systems. They serve as the basis for synchronization between system components and are used to provide timing signals for operations such as data transfer and sampling. The NB3N1900KMNTWG is one such device, and as a part of CML Microcircuits’ Sabre Series, it is designed for a variety of clock/timing applications.

The NB3N1900KMNTWG is an integer-N frequency synthesizer, a type of device offering superior performance over standard frequency synthesizers. It has a broad N divider frequency range of 4 kHz to 200 MHz, providing excellent flexibility and enabling multiple frequency-hopping sequencing modes. Along with the frequency synthesizer, the NB3N1900KMNTWG has self-adjustable/programmable slew rate control to reduce close-in phase noise and EMI, plus a wide range of pulse control output capability.

The NB3N1900KMNTWG is well-suited for applications requiring superior performance or those that must operate within tight power or size constraints. It is compatible with the 3V supply voltage levels found in many RF and digital systems, enabling the construction of cost-efficient and highly-integrated devices. The device has an operating temperature range of -30°C to +85°C and is packaged in a 8x8mm² QFN, making it well-suited for handheld and portable applications.

The NB3N1900KMNTWG operates by generating multiple output clocks of correct duration, frequency and phase. An integer-N frequency synthesizer is essentially a circuit which divides an input signal by a binary number to produce a frequency-stable output. This N number can be varied with a programmable divider, enabling the output frequency to be varied. By sequencing between different divider values, it is possible to generate multiple frequencies with the same input clock. The NB3N1900KMNTWG utilizes two output dividers, enabling it to generate multiple output channels independently and concurrently.

The power supply conditioning feature of the NB3N1900KMNTWG helps to protect it from external noise and allows it to be powered from a single supply rail. The slew rate control of the device allows precise adjustment of the output rise and fall times, ensuring that the output signals accurately match the desired frequency and duty cycle. Additionally, the NB3N1900KMNTWG has integrated protection against ESD, which helps protect it from voltage spikes and transients.

The NB3N1900KMNTWG is designed for clock generation and frequency conversion applications in a variety of market segments, including military/defense, aerospace, commercial, telecommunications, industrial, automotive and consumer products. Typical applications include RF/microwave transmitters, receivers and test equipment; motor controllers; clock/frequency synthesizers, generators and dividers; frequency modulators; and analog-to-digital and digital-to-analog converters.

In conclusion, the NB3N1900KMNTWG is an ideal choice for applications requiring superior performance and flexible frequency synthesizer capabilities. It is designed for 3V supply voltage levels, enabling it to be used in a variety of systems, from portable to high-power applications. The device has a range of features, including ESD protection, power supply conditioning and slew rate control, making it well-suited for clock generation and frequency conversion applications.
