The NBC12439AFNG is a clock/timing device that includes a clock generator, phase-locked loop (PLL), and frequency synthesizer. This device provides precision frequency and phase lock of reference clock inputs, enabling application flexibility and reducing system complexity and size. It supports a wide range of frequencies, including frequencies up to 600 MHz, and can generate a variety of analog and digital output formats. This makes it ideal for applications requiring precise and accurate timing, including data acquisition systems, telecommunications equipment, precision instrumentation systems, and industrial control systems.

The NBC12439AFNG clock generator is a complete frequency synthesis solution. It features a low noise wideband voltage-controlled oscillator (VCO) and two high performance VCXOs for fast switching between clock frequencies and locks. The device also includes a phase detector, programmable loop filter, and a charge pump to ensure precise frequency control. The PLL integrates a reference clock monitoring circuit to detect and react to frequency reference variations for precise locking. A reference clock input buffer is included for improved noise immunity.

The frequency synthesizer combines a classic frequency divider with a frequency selection register. This allows the user to select from a range of frequencies by writing patterns to the register. The device supports a wide range of frequencies, including frequencies up to 600 MHz. It also has an output enable pin to control the output when the output frequency is not needed. Other features include enable/disable control of the reference clock input, output clock control, and register programming.
