... DOCSIS 1.1 and the DOCSIS 1.0 standards. The world’s fastest, lowest power and smallest cable modem solution, the CX24951, offers 500 MIPS of processing power while consuming just 550mW in a 17mm x 17mm BGA package. The CX24951 fully supports the new upstream physical-layer modulation technologies A-TDMA (Advanced Time Division Multiple Access) and S-CDMA (Synchronous Code Division Multiple Access) as specified in DOCSIS 2 ...

... Broadband Modems Cable Modems The dual processor architecture of the CX24951 allows used in CableHome applications, without needing an additional network processor for the firewall and routing features required by the CableHome standard. The firewall and routing algorithms required by CableHome take less than 10 percent of the 500 MIPS processing power of the CX24951, leaving plenty of processing power left for developing custom networking applications ...
