8N3Q001LG-0090CDI8

8N3Q001LG-0090CDI8 is widely used in the field of clock/timing and programmable timers and oscillators. It is a kind of programmable timer and oscillator which combines the PLL clock synthesizer and programmable timer technologies.

8N3Q001LG-0090CDI8 can be used to generate a wide range of frequency outputs in the range of 3.2kHz to 480MHz, with excellent accuracy, low power consumption and a wide operating temperature range. The device can be programmed via I2C or SPI interfaces which make it an ideal choice for industrial and consumer applications.

The working principle of 8N3Q001LG-0090CDI8 comes from its PLL circuitry. PLL stands for Phase locked loop which works by taking an input frequency, such as a crystal oscillator, and by comparing it to the generated output frequency with a phase comparator. It then adjusts the generated frequency to match the input frequency until the output frequency and input frequency are the same.

The 8N3Q001LG-0090CDI8 consists of a device core and an external control logic. The device core contains an internal clock synthesizer, a programmable timer and an output terminal where the generated frequency can be output. The control logic consists of a digital control unit and an input/output interface. The digital control unit is used to program the timer while the I2C/SPI interface enables the setting of the timer parameters.

Once the parameters are programmed and the timer is enabled, the internal clock synthesizer will begin to generate the desired frequency output, which will be rectified and buffered by the PLL circuitry, providing a stable frequency output. This output can be output via the output terminal or fed to other consumer devices to drive or synchronize them in terms of clocks.

In short, 8N3Q001LG-0090CDI8 is a highly accurate and low power programmable timer and oscillator, which can generate a wide range of frequency outputs in the range of 3.2kHz to 480MHz. It is suitable for use in industrial, consumer and automotive applications where precision and accuracy are important.
