It is designed to operate both with external reference oscillators and with in-line oscillators, allowing for more flexibility. This PLL synthesizer\'s output can be used to feed a variety of low-jitter clock synthesis applications, from desktops to gaming consoles and beyond. Its unique architecture gives it a wide range of benefits over traditional frequency synthesizers and PLL designs.

Application Field

The 5P49V5913B509NLGI8 is a cost-effective and reliable solution for systems that depend on clock frequency and low jitter outputs. Its higher levels of integration and programmability featured in the IC architecture makes it suitable for applications in communications, computing, consumer electronics, industrial, instrumentation and medical electronics.

Thanks to its wide-out frequency range (from 1 kHz to 200 MHz) and selectable bandwidths, it can be used in high-performance applications such as DDR2/DDR3 memory controllers, digital audio and video devices, GPS receivers, multi-gigabit backplanes and multi-interface Ethernet switches. In addition, thanks to its low power requirements, the 5P49V5913B509NLGI8 is a cost-effective solution for total power supply reduction.

Working Principle

The 5P49V5913B509NLGI8 is a low-jitter clock generator which combines a single-ended input reference clock with an automated programmable PLL. This PLL is comprised of an integer factor synthesizer (IFS), which allows for wide frequency adjustment range and small steps, as well as a variable-gain amplifier (VGA) for setting the loop bandwidth and compensating for gain margin.

Depending on the input frequency, the IFS selects the needed reference frequency. In this way, the 5P49V5913B509NLGI8 eliminates the need for manual de-tweak to match the output frequency.

The 5P49V5913B509NLGI8 also retimes the phase of the clock, providing a phase offset on the clock edge relative to the reference clock. This is done by the phase-locked loop (PLL) whose feedback loop cannot be broken as long as the reference clock is present and whose phase-shift is dependent on its parameters.

The 5P49V5913B509NLGI8 can also be used in synchronization applications, linking multiple synchronous clock sources together. In this case, the output frequency of the 5P49V5913B509NLGI8 will depend on the percentage of synchrony between the reference clock and the slave clock.

In summary, the 5P49V5913B509NLGI8 is an ideal choice for applications requiring clock speed, versatility and low jitter. Its wide range of frequency covering from 1 kHz up to 200 MHz, as well as its selectable bandwidths, make it suitable for applications in communications, computing, consumer electronics, industrial, instrumentation and medical electronics.
