The NBC12439AFAG is a frequency synthesizer in the Clock/Timing – Clock Generators, PLLs, Frequency Synthesizers category, designed to generate a reliable clock signal from an input reference signal. Its application field can range from telecommunications to consumer electronic products and applications, such as broadband servers, routers, and other high speed communications products including modems, switches, bridges and POS (Point of Sale) systems.

The NBC12439AFAG uses a phase-locked-loop (PLL) circuit to accurately synthesize and generate a frequency, typically between 1MHz and 1GHz. It works by forming a feedback loop to accurately measure and derive the frequency of an input reference signal. This reference signal is typically from a quartz crystal-based oscillator, which produces an accurate frequency at the precise frequency that is provided to the PLL.

The NBC12439AFAG is designed to select and generate frequencies that fall within a designated range, making it versatile for multiple applications, such as voice and data networks, computer networks, healthcare, military, and aerospace systems. When configured for automated frequency selection, the NBC12439AFAG can select from up to 128 frequencies within the range of 1 MHz to 1GHz. It features an adjustable frequency range and can be programmed to select the optimum frequency for any specific application, such as SCSI, Fibre Channel and other high speed digital applications.

The NBC12439AFAG is also compatible with standard digital-bus protocols. Furthermore, depending on the application, it has the capability to provide multiple outputs such as UART (Universal Asynchronous Receive and Transmit), Serial ATA, I2C and SPI (Serial Peripheral Interface) interfaces. All of these output ports can be configured to operate concurrently.

The NBC12439AFAG has several performance features including wide input voltage range, low power consumption, small form factor, and low EMI (electro-magnetic interference) emissions. It also features programmable frequency stability and jitter, as well as dedicated output enable/disable control lines. Additionally, the NBC12439AFAG features synthetic pull-in range, which allows it to quickly lock onto its reference signal and provide a reliable output signal.

In summary, the NBC12439AFAG is a frequency synthesis model that falls in the Clock/Timing – Clock Generators, PLLs, Frequency Synthesizers category. Its application field is broad, ranging from telecommunications to consumer electronic products, and it uses a PLL circuit to accurately synthesize and generate a frequency in the range of 1MHz to 1GHz. It features an adjustable frequency range, multiple output ports that can be configured to operate concurrently, wide input voltage range, low power consumption, small form factor, low EMI emissions, programmable frequency stability and jitter, and dedicated output enable/disable control lines. Finally, it also features synthetic pull-in range, which allows it to quickly lock onto its reference signal and provide a reliable output signal.
