Hi all
I looking for compaq presario 1200-xl-126 laptop service manual,
I would like to know how to replace the bios in the motherboard by PLCC
in order to fix turn off problem.
Thanks in advance...
Re: OrCAD PSpice bug?
Pspice requires a node number in order do instance a component, you cannot
insert a component without these informations.
.subckt a b xx
v1 a b 0V
r1 a b 1k
.ends
and if you want to use several subcircuits in parallel
x1 1 0 xx
X2 1 0 xx
X2 1 0 xx
or in...
Hi
Try this read the book "Digital Signal Processing with FPGA"
it has many examples of filters implementation using VHDL scripts:
part1: h**p://rapidshare.de/files/8031212/Digital_Signal_Processing_with_FPGA.part1.rar.html;
part2...
Can Someone help?
I would like to know if behaviour models described utilizing VHDL-AMS
scripts (ieee libs) can be implemented in FPGAs or only simulated.
Thanks
Re: LVTTL in Spartan IIE?
Thanks DELAY,
I am employng LVTTL because the output data from A/D board is 5V , once it is provided through the buffer SN74ABT16244A.
LVTTL is one of the available IOBs compatible with this level according
with SPARTAN-IIE datasheet.

Please,
I am trying to acquire a databus (12 bits) from an A/D converter
(with sample rate configured at 50MHz) using SPARTAN IIe and IO buffer configured as LVTTL (SLEW) in the input pins of UCF file (ISE 6.1i).
Is the LVTTL (SLEW) IOB fast enough to be activated by the...
I have a DIGILENT D2S board with Spartan2E- (XC2S200E) with 50MHz clock in the board and one A/D converter ADS2807 from Texas. The A/D works with the clock range from 100Khz up to 50MHz, and do the conversion in continuous acquisition mode.
I would like to know if is safe to create a clock with...
orcad multiplier
Djalli,
Both voltage sources (Vif=>Vsin component and Vmod=> Vpulse component) you can find in SOURCE library and the component MULT in ABS library.
You need to add these two libs in your project (Capture or Schematic), before to use the components.
I am looking for an high-speed AD converter that can read AC signals(+DC component) with variable frequency (30kHz---300kHz) and 5V peak voltage.
It must have sample rates between 30Mhz and 50 Mhz with/more 10 bits of resolution.
Thanks in advance!!!
Does someone know what is the difference between using only
the * to do one multiplication with 2 signals (10bits each one)
..." Result <= Sigal_A * Signal_B; "....
and do the same operation using the coregen multiplier block(ISE 6.1i).
Thanks in Advance...
Thanks kkdelabaca...
I will try your suggestions....
But actually, I’m interested in a circuit drive using only discrete components (Optos, Transistors, R,etc) without specific ICS
Does someone know How to drive IGBT for Digital Motor Control using 3.3V DSP Output?
Some IGBT circuit drivers require a 15V CMOS input level;
I´m interested in the circuit needed to interface the DSP to such drivers.
Thanks in advance...
Re: PWM Controllers
Hi, what is the operation mode that your boost will work ? Continuous or Discontinuous operation mode.. with constant frequency or with variable frequency?? (dc-dc/ac-dc) ??
The rigth IC depends that.. but you can try UC3842, UC3852, UC3854
from TI -
