The MC100EP40DT is a programmable clock generator and highly configurable PLL frequency synthesizer. It is capable of producing frequencies up to a frequency of 100 MHZ and has an operating temperature range of -40°C to 85°C, making it highly suitable for embedded applications. The MC100EP40DT includes a highly-integrated digitally controlled resistor (DCR) module which can achieve fine resolution control of frequencies, utilize a low-power type-C bias current, and provide best-in-class PLL stability. Its broad tuning range and configurable loop filter blocks make it highly suitable for a variety of clock application needs.

MC100EP40DT are used in a wide range of clock application fields, particularly in communications, computing and advanced power management applications. With its unique features, the frequency synthesizer can also be used in system/memory controllers, data conversion, ASICs, industrial control and medical instrumentation.

The MC100EP40DT has four different working principles:

• Dynamic Tuning Synthesizer (DTS): This working principle allows for dynamically changing the frequencies of the PLL synthesizer over a wide range. This makes it possible to adapt to fast moving system parameters and performance in many applications.
• Phase Lock Loop (PLL): The PLL of this synthesizer makes use of a reference clock, which is then compared to the output of the synthesizer at a predetermined ratio. This results in an output that is synchronized with the system’s impacting conditions and allows for greater flexibility and stability.
• Constant Frequency Synthesizer (CFS): This working principle allows for stability at the cost of long-term frequency accuracy. This makes it suitable for critical applications that require stable frequencies without significant fluctuation.
• Fine Frequency Synthesizer (FFS): Finally, the FFS principle provides the most accurate frequency control, allowing for dynamic frequency changes with small increments. It makes the most of the highly integrated DCR module for this purpose and is ideal for applications that demand high accuracy and reliability.

In summary, the MC100EP40DT is a high-performance, wide-temperature, programmable PLL frequency synthesizer. Its broad tuning range, various working principles and integrated DCR module make it suitable for a wide range of clock applications, especially in communications, computing, industrial and medical instrumentation. Its fine frequency resolution and highly configurable loop filter blocks further increase its flexibility and make it ideal for use in many different applications.
