The MK3711DMILF is a highly versatile clock generator from Mitel Semiconductor. It is a high-frequency, wide-range programmable oscillator with a distributed feedback (DFB) PLL. The device uses a programmable master reference to provide a wide range clock output frequency selection range from 10 MHz to 600 MHz. The MK3711DMILF also has a wide selection of output formats such as CMOS, LVCMOS, SINE, and TRIANGLE waveforms.

The programmable master reference is a key feature of the MK3711DMILF, as this allows it to generate outputs at multiple frequencies and waveforms. The reference clock can be programmed to output waveforms of 10 kHz to 10 MHz. This eliminates the need for multiple external components such as crystal oscillators, voltage-controlled oscillators (VCOs), and frequency dividers to achieve various frequency outputs.

The MK3711DMILF can also be used as a high-frequency clock generator. It can output clock frequencies up to 600 MHz. This is made possible through its frequency synthesizer which uses a phase-locked loop (PLL) to synthesize higher frequency outputs. The synthesizer also has programmable step size of 1 Hz or an option for a user-defined step size.

The MK3711DMILF is a very versatile clock generator and can provide a wide selection of waveforms and frequencies. It is most suitable for applications such as automotive, avionics, communication and industrial control systems. In addition to its clock generation capabilities, it can also be used as a frequency synthesizer, programmable PLL, and digital phase discriminator that can generate signals with ultra-low jitter.

The working principle of the MK3711DMILF can be divided into four different phases. First, the input reference clock is divided down to the desired frequency using a frequency divider circuit. Next, a phase-locked loop (PLL) is used to synthesize higher frequency outputs. The PLL is then used to compare the phase of the input signal and the output from the frequency Synthesizer. The error signal is then used to adjust the phase of the output in order to achieve the desired synchronization.

Finally, the output from the PLL and frequency synthesizer is provided to the output drivers, which can be configured as either single-ended or differential devices. The output drivers provide the detailed waveforms and frequencies as programmed. The device also has many programmable features such as power down mode, power supply select, reset, and interrupt capability.

The MK3711DMILF is an ideal clock generator or frequency synthesizer for many applications. Its high frequency range, wide selection of waveforms, programmability, and reliability make it an excellent choice for projects requiring clock generation and frequency synthesis. It is well-suited for automotive, avionics, communication, and industrial control systems that require ultra-low jitter and high-frequency outputs.
