Spread Spectrum Cores ??

Does anyone know of freeware spread-spectrum cores; particularly DS ?

I'm looking for something which basically takes serial-data in and drives a GMK modulator at the output. Small, configurable, and with a simple DS scheme that doesn't have stringent acquisition needs.

Issues are cost (complexity) and power; not security or speed (1mb/sec is fine).

ps; any suggestion of 'standard parts' would be appreciated as well...

thanks much

Yes, there is a spread spectrum clock generator : The LTC6902 5kHz to 20MHz multiphase capable. For 2.90$.

hello Rene,

thanks for your reply....but that sounds like a motherboard/cpu clock generator....not an SS radio chip. I am looking for cores or IC's which generate or modulate an RF signal.

Hi,

You can get a look at Zilog Z-87200 which is a new version of the original Stanford STEL-2000...

At Harris or Intersil : PRISM 2.5 chipset

At COMBLOCK : COM-1018

And so I'm very interested if you buy a DSSS chip to cross correlate your results : sensitivity, SNR, BER... with our chip companie (we don't sell it), we have developped with a Stratix FPGA a DSSS transceiver DQPSK/DBPSK 4Mbps/2Mbps.
