The 87002AG-02LF is a low-power, dual-frequency clock frequency generator from Ecliptek Corporation. It is designed to provide a wide range of outputs for a variety of different applications, including those in the digital and audio/video industries. The 87002AG-02LF is ideal for applications that require low-power, consistent, and accurate clock generation.

The 87002AG-02LF features two independent oscillator outputs and a sinewave output. It is based on an innovative Fractional-N PLL that enables users to adjust the output frequency between 1MHz and 200MHz in steps of 1MHz. The fractional-N PLL design provides improved signal-to-noise ratio (SNR) and better jitter performance than other clock generator designs. The 87002AG-02LF also offers a high-efficiency power consumption of less than 500mW, as well as wide operating temperature range from -40°C to 85°C.

Application Field

The 87002AG-02LF is suitable for digital applications such as DSPs, ASICs, and FPGAs, as well as for audio/video applications such as switch matrixes, digital receivers, and display devices. With its low-power operation and wide temperature range, the 87002AG-02LF is well suited for use in industrial, automotive, and clean-air environments. The product is RoHS and REACH compliant.

Working Principle

The 87002AG-02LF operates on the principle of Fractional-N PLL Frequency Synthesis. This method of frequency generation uses a voltage-controlled oscillator (VCO) to generate a series of harmonically related frequencies. The output frequency is controlled by varying the voltage supplied to the VCO. By selecting the desired output frequency, the required voltage is determined and provided to the VCO.

The 87002AG-02LF includes a dual-frequency PLL circuit that contains dividers, mixers and loop filters. The dividers generate a reference clock with a frequency that is the input clock frequency divided by an integer, while the mixers combine the reference clock and the VCO output to produce the desired output frequency. The loop filter then uses the differences between the input and output frequencies to adjust the VCO voltage accordingly.

Overall, the 87002AG-02LF is an ideal device for low-power, accurate, and consistent clock generation. With its dual-frequency PLL design, wide operating temperature range, and low-power consumption, the 87002AG-02LF can be used in a variety of applications.
