M2041-12-622.0800T is a type of clock generator, phase-locked loop (PLL) and frequency synthesizer. Its application field and working principle are discussed in this article.

Application Field

The M2041-12-622.0800T is an integrated frequency synthesizer and PLL for Clock Generation. Its application field is widely in clocks (including frequency synthesizer and synthesizer-based clock tree), telecommunications equipment (including SONET and Ethernet networks), industrial controls equipment and high speed data converters. It can serve as a stable reference clock to generate precise frequency signals to control high speed BIOS/CPU frequency, memory/bus/peripheral speed, as well as replace crystals and oscillators to reduce their physical sizes and power consumption.

Working Principle

The M2041-12-622.0800T uses a phase locked loop (PLL) to synthesize the desired frequency. The output of the clock generator is locked to a reference clock. The reference clock is used for phase comparison and to provide the minimum discrimination needed for the PLL to reach a phase lock. The reference clock can be programmed externally to provide flexibility. The user also has control over the output frequency through the use of a serial or parallel programmable divider, among other factors. The output frequency is determined by the following equation:

Output Frequency = (Reference Frequency) / (2^n * (k + dividend))where	n is the number of bits in the programmable divider	k is the value programmed into the divider and	dividend is an offset value

This equation takes into account the reference frequency, the number of programmable divider bits, the programmed divided value, and an extra offset divider. By adjusting the reference frequency and programming the divider, users can customize the M2041-12-622.0800T to generate a wide range of frequencies.

Conclusion

In conclusion, the M2041-12-622.0800T is a type of clock generator, PLL, and frequency synthesizer. It is widely used in clocks, telecommunications equipment, industrial controls equipment and high-speed data converters. Its output frequency can be adjusted by programming a reference frequency and divider bits.
