Other Parts Discussed in Post: LMK04821 Hello and welcome back to the “ Timing is Everything ” blog series. In a previous post , Timothy T. talked about the clocking requirements of the JESD204B interface standard that is gaining popularity for…
Have you ever done a phase-locked loop (PLL) design with a fractional synthesizer that looked great at integer channels, but then the spurs got much higher on frequencies that were just slightly offset from those integer channels? If so, you have experienced…
Welcome back to Timing is Everything! Last time we covered Understanding PLL loop filter response . Today, I will be helping you learn how to better understand the variety of jitter specifications.
As timing requirements in high-speed applications become…
Most of the JESD204B standard addresses the data interface between logic devices and converters, so what are the clocking requirements? For JESD204B subclass 1, the clocking requirement is quite simple: use the SYSREF rising edge to mark the device clock…
Welcome to our Timing is Everything series ! Today we will talk about the low-voltage positive emitter-coupled logic (LVPECL) since it’s a very popular signal type. In this blog, we’ll go through some key features of LVPECL, its advantages and disadvantages…
Welcome back to Timing is Everything! Last time in our series, we covered how to measure additive jitter . Today, I will be discussing phase lock loop (PLL) systems and how to understand PLL loop filter response. A PLL system consists of a stable and…
Welcome back to our Timing is Everything clock series! Today I will be covering how to select the clock or timing IC that best fits your application .
It’s a fair question to ask: “Is there more to choosing a clock than to just pick one that produces the…
Welcome to the first blog in our new Timing is Everything series ! In this series, you will find all your clock questions and needs addressed by our TI clock experts. I will be kicking off this new series by helping you learn how to correctly measure the…
We’ve likely all seen situations where we’ve needed to sweep the frequency over time. If you are faced with this, consider an application like radar where a transmitted signal is bounced off a target and compared to the received signal, as…
