It offers excellent jitter performance, low power consumption and low cost of ownership. The device is suitable for generating high performance, low frequency clock sources such as reference clocks for communication systems and video interfaces.

The ISPPAC-CLK5620AV-01T100I’sworking principle involves frequency synthesis. This concept is used to create a specific frequency from any given reference frequency. Essentially, the device starts by generating an internal reference clock based on a crystal oscillator. This reference clock is then locked into a PLL circuit. The PLL circuit superimposes multiple, higher-amplitude copies of the original reference, to boost the signal strength. The boosted signal is then multiplied by an integer to create a signal suitable for the output frequency. This multiplication process can also be expressed graphically. Finally, the multiplied signal is divided by a fractional-N divider, which communicates with the PLL, to provide a signal that is exactly the same frequency as the original reference.

In summary, the ISPPAC-CLK5620AV-01T100I is a cost-effective, low power clock generator roundly suitable for a large array of consumer applications. Its frequency synthesis working principle makes it an ideal choice for use in digital TV, set-top boxes, navigation and satellite receivers, audio systems, and game consoles, as it boasts excellent jitter performance, low power consumption and low cost of ownership.
