Hi folks,
I manage a hardware engineering group for a telcom company and I am
beginning to look around for FPGA IP to implement both FSK modulation
and demodulation. I am wondering if any of you have any experience
with any of the IP around today. The demodulator is the most difficult
part and I believe the following list of requirements is fairly close:
* 300 KHz bandwidth
* 5-21 MHz frequency range
* bit rate =3D 39.4 KHz
* modulation FSK, =C4f =3D 75 kHz =B1 10 KHz, fMark =3D fc+=C4f, fSpace
=3D =
fc-=C4f
The modulator would have similar requirements. Any suggestions would
be appreciated. My shop uses both Xilinix and Altera. While we are
most comfortable with FPGAs, a DSP would also be a possibility if good
software is available.
If you think that IP would not be the best choice and another approach
would be better, feel free to make a suggestion.
Biff
