High speed design ??

Can any one explain what is high speed design in PCB ?
is it the same as HDI ?

Hi,

Search Docs in this site and read it.

High speed design ??

I assume HDI is "High Density Interconnect", but HDI PCB is not necessarily a High Speed PCB.

You will find many useful information in the following ebooks:

High Speed Signal Propagation: Advanced Black Magic


High-Speed Digital Design: A Handbook of Black Magic


Digital Signal Integrity - Modeling and Simulation with Interconnects and Package


High-Speed Digital System Design: A Handbook of Interconnect Theory and Design Practices


Emc & the Printed Circuit Board: Design, Theory, & Layout Made Simple


High-Speed Circuit Board Signal Integrity


Signal Integrity Issues and Printed Circuit Board Design

Re: High speed design ??

Dear nicleo,

I had a quick look to the references you listed,
it seems to me that all these books describe in details the problems of the
interconnection path (PCBs, VIAs, Interconnectors ...)

I have difficulties in finding some good reference on the high-speed IC technology (LVDS, CML ...).

Could you help me in giving some reference on the subject?

Thanks,

Satellite

I think if your signal's edge rate is less 2ns,

then you are design a high speed system.


best regards

Re: High speed design ??

Any digital design working above 200MHz system clock frequency is considered high-speed. Some designers claim 100MHz to 200MHz. But if you conform to Xilinx, Altera and HP-Agilent, 200MHz is a de facto.

High speed designing is related to the designing of Critical signals in your board.They can any be anyone either frequency dependent or impedance or length based or any other.
