The AK1546 is a clock generator, frequency synthesizer and a programmable logic device which is used in a variety of applications in communications, industrial and consumer products. It is optimized to provide fast and accurate clock synthesis up to 150 MET and is available in a variety of packages depending on the requirements. The AK1546 is capable of generating clocks at frequencies ranging from 1 to 100 MHz and produces programmable pulse widths of 1, 4 and 8 clock cycles. The device includes two independent phases, a Master phase and a Slave phase, and also includes a number of important features, such as phase noise suppression, adjustable jitter control, and clock skew reduction.

The AK1546 has a variety of applications, most notably in cellular base stations, satellite communications, and GSM/CDMA networks. It is designed for use in applications such as those found in optical systems and automatic test equipment, and can be used in numerous industrial and consumer products such as DVD players, game consoles, digital cameras and other multimedia devices. The AK1546 can also be used as part of a digital phase locked loop (PLL) system or can be used as a digital frequency synthesizer.

The AK1546 operates on the principle of Clock Synthesis. Clock synthesis is a process where a set of input clocks are used to generate a specific output clock. The input clocks are known as the master and slave clocks, and a mixer is used to combine these clocks and generate the desired output clock. Clock Synthesis can be used to create higher frequencies from lower ones, to adjust the phase and frequency from an existing clock signal, or to generate wide range of frequencies from a single clock. The output clock is usually within a few hundred ppm of the desired frequency and can be adjusted within a few percent by adjusting the mixer.

The AK1546 has adjustable features such as jitter suppression and clock skew reduction. Jitter suppression reduces the jitter of the output clock by using a form of digital averaging which smoothes out the output pulse. This helps to increase clock stability and accuracy. Clock skew reduction eliminates the effects of propagation and integral nonlinearities present when multiple clocks are present and connected together. This reduces the amount of skewing in the overall system, improving the overall performance and reliability.

The AK1546 is a versatile device that can be used in a variety of applications and is an ideal choice for applications where low power and low cost are important factors. Its ability to generate high quality clock signals with adjustable jitter, skew and frequency has made the AK1546 a popular choice for a variety of applications. Its ability to generate a wide range of frequencies from a single input clock signal has made it a popular choice for designs requiring a programmable frequency synthesizer.
