The 8V40817QGI is an integrated circuit designed to generate the clocks and signals required in the frequency synthesizers, phase-locked loops, and clock generators. It is suitable in a wide range of clock and timing applications, including oscillators, generators, andmultiplexers. It is also widely used in industrial controls, consumer electronics, instrumentation and communication systems.

The 8V40817QGI is a programmable integrated oscillator that provides the necessary signals for clock and timing functions. In addition, the on-chip frequency synthesizer offers multiple frequency ranges, allowing users to achieve precision timekeeping accuracy. The frequency ranges offered by the 8V40817QGI include fractional-N, integer-N, direct-digital synthesizer (DDS), and multi-N frequency synthesis modes.

The 8V40817QGI features a low power consumption level and low operating temperature, making it suitable for battery-operated and thermally-restricted environments. It features an ultra-low jitter on a wide range of frequencies and itsdesigned to meet the stringent requirements of Network Time Protocol (NTP) requirements. Its very wide frequency coverage allows users to obtain clocks of up to 200 MHz while consuming only 4.3 mA. This low power consumption helps to reduce system cost and improve overall performance.

The 8V40817QGI works by generating the clock signal from a crystal oscillator. The frequency of the input oscillator is divided by a programmable frequency divider to create a low-frequency signal. This signal is then multiplied via a phase-locked loop (PLL) circuit to create a synthesized signal with a variable output frequency. The PLL circuit also corrects any error in the original crystal oscillator frequency, ensuring stable output over a wide frequency range.

The 8V40817QGI also features an internal digital-to-analog converter (DAC), which allows it to generate complex clock and timing signals. This feature makes it ideal for applications that require multiple outputs, such as optical transceivers, video signal processing, and networking. In addition, the 8V40817QGI supports a wide range of interface types, including USB, I2C, SPI, and HDQ.

The 8V40817QGI is a highly configurable and reliable integrated circuit that is highly suitable for a wide range of clock and timing applications. Its low power consumption, wide frequency range, programmable frequency dividers, and built-in PLL all make it a reliable choice for many signals and clock applications. Its wide range of supported interfaces also make it versatile for use in a variety of applications, including networking and optical systems.
