The MK1709STR is a type of clock generator, phase locked loop (PLL), frequency synthesizer. It is designed for use in the consumer electronics market, mainly within the computer industry. Its main purpose is to generate a stable, accurate, and programmable clock signal from an external crystal oscillator.

The MK1709STR has a range of operating frequencies from 13.50MHz to 214MHz with a frequency resolution of 0.25MHz and a cycle jitter of 2.5ns. The adjustable output voltage is +3.3V and +5V. It also supports three different control modes, including the standard pulse-width modulation (PWM), the variable duty cycle PWM, and a 50/50 duty cycle PWM.

The MK1709STR phase locked loop (PLL) is used to compare and lock the phase relationship between the reference crystal oscillator and the internally generated clock. It works by multiplying or dividing the differential frequency between the reference oscillator and the loop oscillator, resulting in a stable output frequency. This frequency can then be used to control logic circuitry or digital timing signals.

The frequency synthesizer in the MK1709STR supports two input methods: transfer mode, and feedback mode. In the transfer mode, the frequency synthesizer accepts an input from the reference crystal oscillator and transfers it to the output frequency. The feedback mode supports a direct input of either the output frequency or the input frequency, which is also known as the "divisor output".

In the feedback mode, the frequency synthesizer is used to generate a stable reference frequency from the input frequency. This reference frequency is then used as the starting point of the transfer mode, which allows the frequency synthesizer to generate an output frequency that is proportional to the input frequency, but higher in frequency. By changing the input frequency, the output frequency is also changed accordingly.

The MK1709STR is also capable of generating sequences of up to 16 different frequencies in a single period. Programmable pulse masks and clock outputs are also available, as well as user selectable active/inactive states and Enable/Disable inputs. This allows the device to be optimized for many applications, ranging from automotive and aerospace components to PC motherboards and home entertainment systems.

The MK1709STR is a reliable and cost-effective device designed for use in a variety of applications. It is capable of generating high accuracy and stable clock and frequency output signals with low power consumption, making it an ideal solution for modern digital and communications devices.
