  • 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...
  • In my previous post, Understanding the protocol , I took a high-level functional look at the three states within the JESD204B protocol that are critical to establish a valid data link between the TX and RX portion of the link: code group synchronization...
  • Welcome back to the Get Connected blog series here on Analog Wire ! In the previous Get Connected blog post, SerDes XAUI to SFI design , we took an in-depth look at using the TLK10232 in a XAUI to SFI protocol converter design. In this post, we are going...
  • Have you noticed how differential signaling is becoming more and more dominant in high performance signal paths? Differential signaling offers several advantages! I’ve been thinking about the fact that every differential signal path has a parasitic...
  • Did you know that at least one voltage reference is used in almost every application? This is because a reference point is typically required somewhere inside the signal chain of a system. Voltage references are most commonly used as a reference for data...
  • As many of you know, jitter (which is clock edge uncertainty) is a bad thing that leads to increased noise and degradation of a data converter’s ENOB. For example, if we have a system that requires an ENOB of 14 (minimum) bits at 100 MHz,...
  • I’ve learned a lot about the JESD204B interface standard while designing systems with our latest analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), which use this protocol to communicate with FPGAs. I’ve also read...
  • 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...
  • This post was co-written by Dave Long and Jose Gonzalez Connecting devices to one another has gone from a cool idea to a must-have. From activity trackers to smart homes, we see the need for more data to be exchanged among numerous types of devices...
  • 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...
