The MK2308S-2LF is a Clock Generator, PLL, and Frequency Synthesizer in one device. It is specifically designed to provide superior phase and frequency stability in a wide range of applications. The device has an integrated phase-locked loop (PLL) with an embedded frequency synthesizer, allowing it to generate and synthesize frequencies over a wide range. It also features two phase-locked loop (PLL) outputs that can be selected to drive a wide range of clock generators.

The MK2308S-2LF is especially well-suited for use in embedded systems such as broadcast video equipment, automobile navigation systems, and communication systems. It can also be used in GPS receivers, medical equipment, and automotive infotainment systems. Additionally, it is suitable for designing synchronous clock generators for clocks, automotive timing devices, and crystal oscillators.

The MK2308S-2LF consists of a programmable frequency control register and a compound PLL circuit. The frequency control register sets the reference frequency divider and the feedback divider settings to generate the synthesized output frequency. The PLL circuit is designed to minimize jitter, minimize frequency drift, and maximize phase/frequency lock performance. By combining the frequency control register settings and PLL settings, users can achieve precise control of their output frequencies.

The MK2308S-2LF has two outputs designed to drive clock generators or synchronous crystals. Outputs 1 and 2 can generate frequencies up to 2MHz and up to 3.2GHz respectively. The device features an adjustable power supply to enable operation in low noise environments, and adjustable current limit for fast response voltage regulation. The integrated temperature compensation increases the stability of the output frequencies across temperature.

The MK2308S-2LF is also designed to minimize EMI issues by including built-in ESD protection and an integrated EMC filter circuit. The on-chip voltage regulator eliminates the need for an external regulator and minimizes external components, reducing the system cost. Additionally, the device is constructed with a low-power CMOS process for improved stability, small form factor, and low power consumption.

In conclusion, the MK2308S-2LF is a versatile and reliable device designed to provide superior phase and frequency stability in a wide variety of applications. It features an integrated PLL and frequency synthesizer, two high-speed PLL outputs, adjustable current limit, adjustable power supply, temperature compensation, ESD protection, and EMC filter circuit. This combination of features and its small form factor make it an ideal choice for embedded and automotive clock applications.
