The MK5812STR from Maxic Semiconductor is a dual-output programmable clock generator and is used in a variety of applications such as clock and data recovery, data switching, and general-purpose timing needs. It has a wide operating range from 9 MHz to 960 MHz, and can be programmed using either I²C or parallel ports. The device is composed of two independent 90° phase shifted digital controlled oscillators (DCOs), two internal low power dividers, and two low jitter digital clock outputs.Due to its wide operating range, the MK5812STR can be used in a variety of applications such as digital logic, multi-media, and medical device applications as well as instrumentation and simulation systems. In addition, the device offers a variety of features such as programmability, spread-spectrum frequency selection, clock synchronization, and phase shifting.In terms of the working principle of the MK5812STR, the device utilizes a phase-locked loop (PLL) architecture to generate two clocks with independently adjustable dividers and phase adjustments. The output clock frequencies can be adjusted manually or via an I²C or parallel interface in order to adjust the PLL loop parameters for best performance based on the user\'s needs.The MK5812STR can also be used with spread-spectrum clock technology, which helps to reduce EMI emissions by introducing a deliberately smaller peak-to-peak amplitude. By programming the device, the user can adjust the amount of spread-spectrum frequency and the deviation from the desired clock frequency.The dual-output programmable clock generator features low cycle-to-cycle jitter and is designed to provide a low-noise and low-power solution for a wide range of applications. The device has a wide input frequency range that allows for clock synchronization and can help reduce board space for applications requiring multiple clock sources.The MK5812STR is the ideal choice for a wide range of clock generator applications and is available in a variety of packages and pin configurations. The device is well-suited for use in digital logic, multi-media, and medical device applications as well as instrumentation and simulation systems.
