Crosstalk video demonstration for stripline

by

A short video to demonstrate crosstalk and try to explain how that works in the stripline environment. We look at both the near-end and far-end crosstalk and also explain why that depends on the termination used. Direct YouTube link. In a real digital circuit, we will have one of these termination situations: Open/high impedance (typical… Read more

Video: Using a Network Analyzer as a TDR

by

See how you can do fast TDR measurements using a network analyzer or VNA in this video. Whenever you are designing boards with specific characteristic impedances, you will want to be able to verify that on your fabricated boards. It’s recommended to put in test traces on each layer, but how do you measure this.… Read more

Video: PDN Measurement with a Network Analyzer

by

See how easily you can do a PDN measurement using a network analyzer or VNA in the video here. Building solid power distribution systems (PDN’s) is maybe the most important learning from the signal integrity training overall. Because it matters. Both for the logic functions, the signal quality (integrity) and for the radiated emissions (EMI).… Read more

Win a Crazyflie

by

The great guys at Bitcraze have created a super nice small remote controlled flying eval board with the Nordic Semiconductor nRF24L01+ 2.4 GHz radio chip and the ST Arm Cortex M3 based micro controller STM32F103CB.  It’s really a nice little toy that can be used for both fun and learning. We are giving one of these… Read more

How long is a Nanosecond in electronics?

by

Watch this classic clip featuring Grace Hopper to learn how long a nanosecond is. And why it is so useful as an educational tool. I still use that today whenever I do the 3-day signal integrity training course. And happy 107 year birthday to Grace Hopper (December 9, 1906 – January 1, 1992). Such an… Read more

How Laminate and Prepreg is made

by

Knowing how laminate/prepreg is manufactured matters. Communication starts with understanding each other. This is why board-level design engineers need to understand how PCB’s are being manufactured in much detail. Because modern high-speed designs require a lot of communication between the board designer and the PCB manufacturer. In the course “Lee Ritchey: Stackup Design” we go… Read more
