Spread Spectrum Cores ??

Question

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$.Rene-- Ing.Buero R.Tschaggelar -  commercial newsgroups -

hello Rene,thanks for your reply....but that sounds like a motherboard/cpu clockgenerator....not an SS radio chip.  I am looking for cores or IC'swhich generate or modulate an RF signal.----== Posted via  - Unlimited-Unrestricted-Secure Usenet News==---- The #1 Newsgroup Service in the World! >100,000Newsgroups---= East/West-Coast Server Farms - Total Privacy via Encryption =---

Hi,You can get a look at Zilog Z-87200 which is a new version of theoriginal Stanford STEL-2000...At Harris or Intersil : PRISM 2.5 chipsetAt COMBLOCK : COM-1018And so I'm very interested if you buy a DSSS chip to cross correlateyour results : sensitivity, SNR, BER... with our chip companie (wedon't sell it), we have developped with a Stratix FPGA a DSSStransceiver DQPSK/DBPSK 4Mbps/2Mbps.
