Hi
yes they can, from a dirty ground or from radiated field inside the mobile phone (each element acts as an antenna) are typical examples. This is the audio buzz !
Mahen,
442ps microstripe is the net between the 7402 output and the T split. 73.8ps microstripe is the 74244 input bonding, 351ps microstripe is the trace between the two 74244 inputs, and the last 73.8ps mictrostripe is the chip bonding.
If you don't take into account the chip bonding, you get...
Hi,
I see, first of all you need to start from the clock. I don't know if your device has dedicated input for clocks, else you need to provide one in a FPGA creating it somewhere. You may use logic gates inside the FPGA for this purpose.
I suggest to create a clock at double the DAC frequency...
Re: how to connect Altera to DAC and program it with VHDL
Hi,
SPI is a 4 wires point to point communication protocol, best way to know how it works is to look at the DAC datasheet to learn the way that component wants to be driven.
For additional information you may check wikipedia or...
Sakhivel,
in Cadence you have SigXplorer (or SigXp) too for SI analisys. If you use Allegro PCB with SI options you have nice add-in feature to design. SigXp is not a great stand-alone tool, but it is well integrated in Allegro
Try to have a look to Cadence documentation.
Regarding process, it...
Hi,
signal integrity (or SI) refers to PCB interconnection design. Therefore each piece of trace needs to be indicated in the simulation model.
Each piece of trace is a TRANSMISSION LINE (like 50 ohm RF stuff you know) characterized by its characteristic impedance (be careful it is not...
Hi
don't know if there is any specific magazine related to SI, all I have always found is spread a bit everywhere.
However, you may check in the ressource center of companies provider of components/tools related with SI. They are a good source of information and they make regular updates:
1 -...
Re: Need USB connector tosupports both charging and headpho
I think your problem is not the USB connector (a connector is a dummy thing) but the mixing before them. USB provides 5 connections:
Power Supplies
Ground
Identification Pin
Differential Data +
Differential Data -
Therefore, you may...
