The MK2308G-1HITR is a versatile clock generator and clock multiplier device. It functions as both a clock synthesizer and a frequency shifter, providing flexibility for many different applications. The device is suitable for low-jitter and low-power clock generation for high-performance digital systems. The clock generator portion of the device provides a wide input frequency range, from 25MHz to 1000MHz, and generates several frequencies from three or two reference clocks. The frequency shifter portion allows users to vary the frequency of the output clocks in tandem with a low frequency reference.

The MK2308G-1HITR contains two clock generator and four frequency shifter modules that are connected in series. The clock generator module takes the input clock and generates five popular frequencies (25MHz, 100MHz, 125MHz, 250MHz, 500MHz). The frequency shifter modules are used to change the frequency of the output signals. The MK2308G-1HITR supports two reference clock ranges, a wide range from 25MHz to 1000MHz and a narrow range from 3MHz to 48MHz. The frequency shifters provide programmable output frequencies from 25MHz to 1000MHz.

The MK2308G-1HITR is used for a variety of applications, such as digital logic circuit timing, system time synchronization, digital video conversion and switching, embedded microcontroller systems and clock distribution. It is also used in digital signal processing (DSP) systems and telecommunications products. The device can be used to generate a wide range of other clock frequencies for synchronous communication, such as network and telephone systems. The device also supports Power over Ethernet (PoE) applications by providing stable clock signals at both ends of the Ethernet connection.

The MK2308G-1HITR features low power consumption and a low noise floor. The device produces low jitter and maintains high accuracy in frequency synthesis and switching. It also provides ESD protection, high temperature operation up to 105°C, and adjustable supply voltage (1.2V~3.3V). The device is designed to withstand harsh environments, making it suitable for automotive, avionics, and industrial applications.

The working principle of the MK2308G-1HITR is relatively straightforward. The device accepts a single input clock at a frequency ranging from 25MHz to 1000MHz, and generates five popular frequencies (25MHz, 100MHz, 125MHz, 250MHz, 500MHz). The frequency shifter module is used to provide a wide range of programmable output frequency ranges. The output clocks are synchronized through the use of PLL technology, allowing the user to accurately set the output frequencies and jitter levels. The device also supports Power over Ethernet, allowing the clock signals at both ends of the Ethernet connection to be synchronized.

Overall, the MK2308G-1HITR is an essential clock generator and frequency shifter device for many common applications such as digital logic circuits, system synchronization, digital video conversion and switching, embedded microcontroller systems, clock distribution, and telecommunications products. The device is reliable and highly accurate in frequency synthesis and switching, making it suitable for demanding and harsh environments.
