The MK1574-01SI is a high-performance frequency synthesizer designed for use in the most demanding timing applications. The device is a highly integrated device with a small form factor, low power consumption, and high temperature stability. It features up to three programmable output frequencies, ranging from 10 MHz to 45 MHz. The device also contains a variety of other features, including programmable reference, programmable division rate, programming mode selection, programmable clock source, programmable output voltage, and an adjustable phase. Additionally, the device can be configured for a variety of other clock sources, including different crystal oscillators, external clock sources, and programmable clock sources.

The MK1574-01SI is a complex device, but it’s easy to understand once you understand the basic fundamentals of frequency synthesis. A frequency synthesizer typically generates multiple output frequencies at the same time, thus providing different signals in parallel. In order to do this, the device integrates a variety of components, such as a reference oscillator, dividers, counters, and programmable dividers.

The reference oscillator, typically a crystal oscillator, provides a stable base frequency which is then divided by the dividers to generate a set of output frequencies. The dividers can be programmable and configured via control registers, allowing the device to be programmed to generate output frequencies from 10 MHz to 45 MHz. The device can also be configured to divide the reference frequency by a factor of 2 or 4, for example.

The programmable dividers are used to divide the output frequencies of the reference oscillator to create the desired output frequency. The programmable dividers can be configured to divide the output frequency of the reference oscillator by a factor of 2, 4, 8, or 16, depending on the desired output frequency. For example, if the reference oscillator is providing an output frequency of 50 MHz, then by configuring the programmable dividers to divide the output frequency by a factor of 8, the output frequency of the synthesizer would be 6.25 MHz.

The programmable dividers are also used to adjust the phase of the output frequency. The MK1574-01SI supports a variety of different phase-adjustment modes, including pulse-width modulation (PWM), frequency shift keying (FSK), and frequency-shift-regeneration (FSR). By adjusting the phase of the output frequency, different signals with different output frequencies can be produced in parallel.

An additional feature of the MK1574-01SI is the ability to select between a wide range of different clock sources. The device supports external clock sources, such as a clock source produced by an external crystal oscillator, as well as programmable clock sources, such as pulse-width modulated clocks, frequency-shift-keyed clocks, and frequency-shift-regenerator clocks. By configuring the device to use an appropriate clock source, the output frequency of the synthesizer can be adjusted to meet the application’s performance requirements.

The MK1574-01SI is designed for use in a variety of applications, such as radio frequency identification (RFID) tags, cellular base stations, and Wi-Fi access points. It can also be used in automotive applications, such as engine control systems and battery management systems. In all of these applications, the device can provide an accurate, low-powered timing solution. Additionally, the device’s small size and low power consumption make it ideal for embedded and mobile applications.
