The MK2746 is a Clock/Timing component specifically engineered for providing frequency sources. It is classified as a Clock Generator, PLL, or Frequency Synthesizer, converting low-frequency input signals into higher frequencies. This product is a PLL (phase lock loop) chip and is typically used in embedded systems controlling communication and graphic capabilities of cell phones, tablets and other embedded applications.

The MK2746 functions by taking a low-frequency input signal and looping it through a phase-locked loop (PLL). A three-stage PLL includes integrated circuit, a timing source, a voltage control oscillator (VCO), a divide-by-two (DIV2) counter, two loop filter components, and two loop gain components. The output of the PLL is a high-frequency output signal generated by the VCO, which has been divided down by the DIV2 counter, and has been synchronized to the input frequency.

The MK2746 PLL is capable of generating Frequencies in the 1.2 to 66MHz range, with a wide range of VCO frequency options. The variablity of the VCO enables the PLL to accurately adjust the output frequency to match the input frequency. The wide range of frequencies that the PLL can generate allows it to be used in applications requiring a wide range of processed frequencies.

The PLL has multiple modes of operation. It can be used in Phase-Locked-Loop (PLL) mode, Direct-Digital-Synthesis (DDS) mode, Frequency and Phase-Synthesis (FPS) mode, as well as Spread-Spectrum-Clocking (SSC) mode. Each mode provides a different set of features and tuning capability.

In the PLL mode, the MK2746 PLL allows for precise and stable frequency synthesis. This mode is typically used for communications, radio frequency, and instrumentation applications. In the DDS mode, the PLL provides high speed frequency-hopping solutions, such as GPS and spreading-spectrum digital systems. The FPS mode is suitable for active filter synthesis, providing real-time adjustment of frequency and phase of oscillations. Finally, the SSC mode is primarily used for EMI reduction in cellular and other applications.

The MK2746 is a versatile device capable of providing high-frequency solutions for a variety of embedded applications. The wide range of frequencies and modes that the PLL can generate makes it an ideal choice for a range of synthesizing applications. With its state-of-the-art components and robust design, the MK2746 can be trusted to provide reliable, accurate frequency output solutions for years to come.
