The MK2308G-1HI is a clock generator and regulator for clock/timing applications. It provides a hight accuracy frequency compensation for the user. The chip integrates a wide frequency and voltage range of oscillators, from low frequency to medium frequency (<50MHz to 400MHz). It provides a wide variety of clock/timing features, including multi-phase clock generation, edge-rate and amplitude controls, variable frequency and voltage, variable slew rate, and programmable edge-delay controls.

Application Field

The MK2308G-1HI is designed for use in various clock/timing applications, such as cellular handsets, digital video broadcasting systems, digital audio broadcasting systems, and PC-based multimedia systems. It can be used in applications requiring precise control over clock/timing signals, such as low-power or high-speed clock generation, differentially driven clock performances, clock signal switching, signal slewing, and clock jitter control. It is also suitable for signal processing applications in communications systems, computer systems, and consumer electronics.

Working Principle

The MK2308G-1HI uses a voltage-controlled oscillator (VCO) to convert an input voltage into a precise clock/timing signal. The input voltage determines the frequency of the VCO output. The VCO can be operated in two modes. In closed loop mode, the VCO output is monitored and adjusted to maintain a precise frequency. In open loop mode, the VCO output can be programmed with a wide range of frequencies.

The MK2308G-1HI also provides digital control and programming. It can be programmed through an I2C or SPI interface. The digital register set allows precise control of clock/timing parameters, such as frequency, phase offset, phase error, total jitter, and phase noise. The device also has programmable output drivers, adjustable slew rates, and various output formats.

In addition to its programmability, the MK2308G-1HI provides high accuracy frequency compensation for the user. The chip is accurate to within 5ppm, which is more accurate than most clock generators. This allows for precise control of the clock/timing signal, resulting in improved system performance.

The MK2308G-1HI is designed to be flexible and scalable, allowing it to be used in a wide range of applications. With its wide range of programming options, the chip can be easily integrated into various clock/timing systems. Its high accuracy and wide frequency range make it an ideal choice for precision clock/timing applications.
