MK1707DLFTR

MK1707DLFTR is a kind of Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers, which has a very wide application field and working principles. First of all, MK1707DLFTR has been designed to provide simple method in frequency synthesis for fastest time to market for digital TV solutions. For applications in other areas such as cable, satellite, mobile DTV, and multimedia applications, MK1707DLFTR is an ideal device for very low power, low cost solutions.

In terms of its application field, MK1707DLFTR can be utilized in both the low frequency range and the high frequency range. In the low frequency range, it is generally utilized to generate housekeeping and control clock signals for microprocessors, PLLs and data converters. The high frequency range of clock generation is mainly used to directly generate video and audio clock signals.

In terms of its working principle, the basic frequency synthesis is based on the Phase-Locked Loop (PLL), which has frequency synthesis as its primary application. PLLs are generally composed of a phase detector, a low-pass filter, a voltage-controlled oscillator (VCO), and a divider stage. The inputs and outputs of the PLL constitute a feedback loop, the function of which is to compare the phases of the input signals to the PLL. When the phases of the incoming signals are different from the contrast signal, the phase detector will output a voltage to adjust the frequency of the VCO . Finally, the VCO generates the output clock frequency, which is close to the desired frequency.

In addition, the MK1707DLFTR also utilizes an external resistor and capacitor to integrate the clock and enable small size and low cost solutions. The MK1707DLFTR features a low reference input frequency range of 5 to 50 MHz, and an output frequency range of 10 to 130 MHz, allowing designs to cover virtually the whole spectrum of clock frequencies required in digital TV applications. On top of that, it utilizes the dual-path Delta Sigma Modulator (DSM) architecture, which achieves exceptional low power dissipation.

It is clear that the application field and working principle of MK1707DLFTR make it an ideal one-stop solution for frequency synthesis applications. The device is specifically designed with optimized circuit design considerations and architectures to enable the highest performance and reliability in the most cost-effective way. With its multi-standard compatibility, low power dissipation, fast lock time and low jitter, the MK1707DLFTR is an ideal device for any digital video and audio applications.
