Clock/timing is one of the most important aspects in any application as it is used to control execution timing within a system. Clock generators, PLLs, and frequency synthesizers are used to create the clocks and timing signals that allow the application system to function. The NBC12430FAR2 is a highly accurate clock generator and frequency synthesizer used to generate clock and timing signals in harsh and rugged applications, such as automotive and industrial. This article will discuss the application fields and working principle of the NBC12430FAR2.

The NBC12430FAR2 has a wide variety of applications, including data communications, portable, broadcast and professional audio, navigation, healthcare and gaming systems, point-of-sale terminals, portable and home entertainment systems, automotive applications, and industrial and military systems. The NBC12430FAR2 can be used to generate precise clock and timing signals for a variety of high-speed bus and communication standards, including PCI Express, USB 2.0, Gigabit Ethernet, Speedwire, Serial ATA, Firewire, and Thunderbolt. It also offers clock frequency translation for high-speed serial video standards, such as HDMI, DVI, VGA, SDI, and DisplayPort. Additionally, the NBC12430FAR2 offers a range of output frequencies up to 150 MHz, adjustable on-chip amplifier gains, and programmable frequency dividers to create precise clock and timing signals with low jitter and high accuracy.

The NBC12430FAR2 utilizes an advanced Frequency Synthesizer-style architecture (also known as an Input Direct Digital Synthesizer or IDDS). This architecture consists of four key components: a oscillator, a frequency multiplier, a frequency divider, and an input-controlled pulse generator. The oscillator is responsible for providing a stable reference clock signal. This signal is evenly multiplied into an even series of values using a Frequency Multiplier. Each value is then passed through a Frequency Divider, which can divide the signal by any number from 2 to 65,535. Finally, the result is the output signal from the Frequency Divider, which can be synchronized to the input reference signal by an internal Pulse Generator. The NBC12430FAR2 also features digitally-controlled analog amplifiers (DCAs) for precise control of the output frequency, with adjustable amplifier gains and aprogrammable frequency divider.

In addition to the high-frequency precision of the NBC12430FAR2, the device also offers a wide operating range and low jitter. The NBC12430FAR2 operates over a temperature range of -40°C to +85°C and is designed to withstand significant environmental and temperature variations, making it suitable for use in harsh and rugged applications. The device\'s low jitter design provides high accuracy and stability for most any application requiring high frequency signals. The jitter-suppression features of the NBC12430FAR2 make it a reliable choice for even the most demanding clock and timing requirements.

In conclusion, the NBC12430FAR2 is a highly precise, low-jitter clock generator and frequency synthesizer designed for use in harsh and rugged applications, such as automotive and industrial. The device utilizes a frequency synthesizer-style architecture to create clock and timing signals with an adjustable frequency range up to 150 MHz. It also features adjustable amplifier gains and a programmable frequency divider. The NBC12430FAR2 exhibits a wide operating range and low jitter, making it an ideal choice for applications requiring precise frequency signals.
