SKY6911x NetSync™ Network Synchronizer Clocks

I'm Nathan Shashoua, product manager for our network synchronizer devices. Today, I want to talk to you about our latest generation of network synchronizer devices, the SKY6911x. These devices are intended for complex systems and distributed systems as in switch and routers and chassis based architectures. The SKY6911x support complex features such integrated time of day counters, as well as input to output delay adjustment and measurement.

The SKY6911x are our first product family that can do this network synchronization function for a distributed system, as well as maintain the low enough jitter to clock high speed 224 gig SerDes. So now I'll dive into the block diagram of the SKY69110, our flagship device. The SKY69110 has 10 input clocks and up to 14 if you drive them single ended, input to output delay measurement and adjustment, and three on chip time of day counters. We have 4 DSPLLs as well as the REF PLL, which can drive our ultra-low jitter output channels to directly clock the SerDes.

This device can generate up to 5 different frequency domains as well as provide 14 differential outputs and a fully flexible input to output MUX. This device has everything that's required for the distributed systems 1588 application. And we've designed the SKY6911x to support all of the existing ToD and sync formats. You can truly plug and play with existing designs without having to adjust the backplane.

We support eTod, which is a single wire clock data and time of day, ePPS, which is clock and sync integrated into a single channel, as well as three wire ToD, clock, sync, and data on three different wires. All of these have been designed and are customizable to support your existing solutions. And while we've designed the chip to support all of the existing formats, we can also offer customizable formats using our ClockBuilder Pro software. Skyworks ClockBuilder Pro software is an easy to use, highly configurable tool for all of our timing PLL devices.

We've brought this same software to the SKY6911x family. Clock Builder Pro allows you to configure all of the frequency settings and configurations of the SKY6911x. And Clock Builder Pro can directly interface with our SKY6911x evaluation board. The board has all the different connectivity required to evaluate the product against your specific requirements.

We have an onboard OCXO as well as an onboard TCXO to test depending on the stability and holdover requirements that you have. The board also features different power supply options, such as directly powering the device with an external power supply or a switching supply to test the performance of the on chip LDOs. We also have onboard LDOs so you can directly compare the performance using a noisy power supply and a clean power supply. Thanks for watching.
