Great info! Thanks to you all for your replies! I think being in class will serve my needs best, so I am going to see which schools offer in class sessions. Thanks, swb1

Hi, Would anyone recommend taking an online course to learn embedded hardware design? It is being taught at a local university. Never took an online engineering course before and don't know how effective it would be. Thanks, swb1

Thanks for your response. I checked out CW. Our current setup has a Synergy 6U VME single board Computer installed as a bus master with a Xycom XVME-100 Memory Module installed in the chassis, so that we can switch between different test programs that we run to test different interface adaptor...

Thanks for your replies! Right now the board that we want to replace is a 6U single board computer that serves as the master in a small chassis that has 5 vme slots where we can place custom interface target cards. This chassis is used as a test suite where we can put custom user test code to...

Hi, I need to replace an old VME circuit card due to obselete parts and have no clue where to begin this design. In doing a VME board design, where would you suggest I start? Thanks, swb1

Cypress makes a programmable clock generator (CY22381) that will seem to work. swb1

Do you have a part that you can suggest?? The PLLs that I have saw have even divides like 2, 4, 6, 8, 12. Thanks, swb1

Hi, Instead of using 2 separate oscillators, is there a way to generate both 33MHz and 64Mhz with 1 device?? The values don't divide evenly. Please let me know. Thanks, swb1

Hi, How do IC manufacturers come up with a power consumption rating?? How do I check their numbers?? swb1

Anyone familiar with how PPMC Monarch vs. Non Monarch mode works?? Our PMC Card will be interfacing with a processor PPMC card, which is requiring our card to run in Non Monarch mode. swb1

I know about Tundra and we didn't want to tie ourselves to a manufacturer. Hence we wanted to use a VME Core and PCI Core within an FPGA and stitch them together. swb1

Hi, Anyone out there have any experience with VME bridges?? I would like to design a PCI to VME bridge using IP Cores in an FPGA device. Looking for the knowledgeable to chime in and give a noobie some tips and things to look out for. Thanks, swb1

Hi, Anyone know of any inexpensive/free analog circuit simulators?? Thanks, swb1

As a lab experiment, I slowed down the bit rate to 1 MHz and there was no difference in the output voltage. swb1

Thanks for replying. I have a 10MHz square wave going in to the Transformer. No DC offset. The output does not change when changing the value of the resistor across the output. swb1

Hi, I am using a 1:1:1 transformer and I have +/- 3.25V going in and +/- 1.6V coming out. Why is this?? Shouldn't the voltage going in be the same as the voltage going out?? I have a differential op amp driving the transformer and 0 Ohm series resistors on the + and - output pins of the op amp...

cbarn, so are you saying that the "on-time" should be equal to or less than the "off-time"?? thanks, swb1

xfmrman, the pulse pulsing the transformer is 600ns wide and happens every 3.3 microseconds. That seems like enough time for the core charge to bleed off. Am I wrong?? swb1

I don't have a .jpg of the schematic, Its done in schema. swb1
