The MK1581-01GITR is a highly integrated single chip PLL Clock Generator that is designed for low-power and low-jitter applications. It can be used for frequency synthesis, clock generation, and synchronous timing generation. It is ideal for multimedia, telecom, and consumer applications where low power and low jitter are the key requirements.

Overview of MK1581-01GITR

The MK1581-01GITR is a highly integrated single-chip PLL clock generator that is designed to provide high accuracy and low power performance. It features a wide range of input frequencies and can generate output frequencies from 1Hz to 1GHz. It has two independent PLLs which can be locked to two different frequencies. The MK1581-01GITR has a very small size and low power consumption, making it ideal for applications where size and power are at a premium.

Application Field of MK1581-01GITR

The MK1581-01GITR is ideally suited for low-power and low-jitter applications such as multimedia, telecom and consumer applications. It can provide low-jitter, high-accuracy clock signals at frequencies up to 1GHz. The highly integrated single-chip PLL design enables power-efficient and flexible clock synthesizing, generating, and timing solutions. It also provides precision jitter attenuation of its output signals that can help reduce system cost.

In addition to its low power designs, the MK1581-01GITR includes a variety of helpful features such as an on-chip reference calibration circuit, a low-power startup mode, an integrated low-dropout regulator, and a spread spectrum capable PLL for improved EMI performance. The PLLs can also be used for fractional-N synthesis, which allows for low jitter output signals in applications where precision frequency accuracy must be guaranteed.

Working Principle of MK1581-01GITR

The working principle of the MK1581-01GITR is based on its integrated PLL circuitry, which consists of a phase-frequency detector and a loop filter, a voltage-controlled oscillator, and a digital frequency synthesizer. The phase-frequency detector receives an external reference frequency and the voltage-controlled oscillator (VCO) output frequency, and produces an error voltage which is then filtered by the loop filter. This filtered error voltage is then used as an input to the VCO. The digital frequency synthesizer produces the desired frequency by combining multiple frequencies produced by the VCO.

The MK1581-01GITR can generate a very wide range of frequencies, from 1Hz to 1GHz, with precision accuracy and low jitter. This is made possible by the fractional-N PLL design, which allows for very fine and accurate frequency tuning through fine steps. The on-chip reference calibration circuit and spread spectrum compatibility can further reduce jitter and improve EMI performance.

In summary, the MK1581-01GITR is an integrated PLL clock generator designed for low-power, low-jitter applications. It can generate wide range frequencies, from 1Hz to 1GHz, with precision accuracy and low jitter. Its on-chip reference calibration circuit and spread spectrum compatibility help to further reduce jitter and improve EMI performance. This makes it an ideal choice for low-power, low-jitter applications, such as multimedia, telecom, and consumer applications.
