8430252CG-45LF

The 8430252CG-45LF is a clock generator and frequency synthesizer IC (Integrated Circuit) designed and manufactured by Intersil Corporation. It is part of the company\'s family of mixed-signal ICs (integrated circuits). The IC is used mainly in communication and digital multimedia technology applications, and its working principle is based on the digital phase-locked loop (PLL).

The 8430252CG-45LF device is a highly integrated timing circuit containing an oscillator, digital phase locked loop (PLL) synthesizer, programmable counter and loop filter. It is designed to generate low jitter and stable clocks in applications such as digital video equipment, audio systems, embedded systems, digital signal processors, and high-speed digital-to-analog converters. The device is constructed with different pin configurations, depending on the application.

The clock generator and frequency synthesizer IC is powered by a single DC supply with an operating voltage range from 6V to 15V. Its integrated phase locked loop (PLL) includes a three-state frame sync signal input, which is used to reset the reference frequency and divide down the frequency by two. The PLL also includes an analog multiple output, a maximum input reference frequency of 1.2GHz, and an analog programmer input for frequency setting.

The integrated oscillator is a low noise type, using frequency extrapolation to reduce the noise, helping to reduce the overall jitter of the clock. The frequency range of the oscillator is up to 500MHz and can be adjusted by setting the bypass capacitor. Digital counter generates multiple frequencies with a programmable duty cycle. The digital phase locked loop (PLL) and integrated oscillator are designed to provide low jitter and stable output clocks.

The 8430252CG-45LF provides a wide range of applications, but is particularly well suited for low noise, frequency diversity applications such as video and audio encoding, multiplexed data streams, as well as advanced communication systems. It is also suitable for use in embedded systems, digital signal processing, and other high data rate wireless and wired applications.

In conclusion, the 8430252CG-45LF is a clock generator and frequency synthesizer IC that is used mainly in communication and digital multimedia technology applications. Its high integration along with low jitter, stable output and wide range of applications make it an ideal choice for a variety of clock/timing applications.
