critical length rise time
when calculating critical trace length, does this trace length start again if you put a buffer chip in the line?
Eg: if you run a data and address line to RAM and EPROM and then to a buffer or bus transciever to go off your pc board to another device on another pc...
sdram layout guideline
yes i too would like information on this, more speicificly. i would like to know tips about the length and width of traces for address and data bus to a RAM module and use of splitting to two or more modules.
What sort of tolerances can there be in the length of...
FGPA Applicaiton??
Well im developing a board with a adc that is gathering data and spitting it out serially. It has been suggested to me that i should use a fpga to clock the serial data out via a sclk and data out, and then buffer it and average the data using a rolling filter and then spit...
Re: Traces and Via's
Im designing a mixed signal board with a micro running at 200Mhz, but it is more the rise time im interested in? which i think will be 6ns. Will this put any limitations on my design?
And if im desinging analoge traces then the only thing i have to worry about is current...
Traces and Via's
well up until recently i had only designed a couple of simple boards at uni, these were really just a matter of playing dot to dot joining connections together.
Now im looking at designing a "high speed board" and have been reading about trace impedance and a milliion other...
bga designing
I am in the process of finding and designing a new micro that will have a 256pin BGA with a 1.00mm pitch (21mm x 21mm). I was origanally thinking of using a 4layer board to do this with sig-pwr-gnd-sig. But after reading around it looks like i should be going to a 6layer board...
ads1251 interface
Hello i am looking for a micro to interface with a adc board. I am hoping to find something cheap that will read in data from the micro at 480kbits/sec serially. We were going to use one of the 64180 variants that we use for other products but it doesnt seem fast enough...
ads1251 schematic
I am in the process of designing a circuit with a 24-bit adc on it. I am wondering if i should devide the ground plane (4 layer with sig-5V-GND-sig) up into digital and analogue. This particular adc (texas ADS1251) does not have a digital supply input. So should i just have...
