  • In a broad sense, “haptics” refers to the feeling of touch. It could be a simple vibration feedback from any human-machine interface, like a smartphone, to recreating surfaces and textures on a tablet screen. Haptics is used to deliver...
  • If you’ve been following my JESD204B series , you have a basic understanding of the protocol and signaling required to establish a link between a JESD204B transmitter and receiver. We can now move on to how to configure the JESD204B link with the...
  • If you strip enough layers off of your optical networking system, you will get to the physical layer― the nuts and bolts of the backbone of communication. The receive optical sub assembly (ROSA) and a transmit optical sub assembly (TOSA) are the keys...
  • Yar Mateys! I’ve been told today is “Pirate Appreciation Day,” or as you land lubbers call it, “Talk Like a Pirate Day.” A day where all those who sail the seven seas stop and raise a mug of grog and appreciate all the hard...
  • Did you know you can design a PCB coil for inductive sensing in five minutes with WEBENCH®? If you are considering using an inductance-to-digital converter , like the LDC1000 , but are concerned about the time it takes to design a sensor coil,...
  • 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...
  • Pick any CMOS or JFET amplifier and you’ll get the lowest possible input bias (Ib) current, right? Not so fast. If you mean low Ib compared to that of bipolar, then yes. But if you mean sub 10pA, there are other factors to consider. Did you say...
  • 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...
