Claude, it was from previous articles I have posted,which are somewhere back in the archives. Well,here is an interesting blurb,directly from ROK.
The chipset provides circuitry to both send and receive high speed data over cable, and replaces earlier receive-only ICs introduced by Rockwell last fall.
The new chipset is fully compliant with specifications developed by the Multimedia Cable Network System (MCNS) consortium. The consortium's Data Over Cable Service (DOCSIS) specifications are expected to be ratified during the first quarter of 1998, and will serve as the basis for worldwide cable modem standards for Internet connections and other data services up to 700 times the speed of today's fastest conventional analog modems.
Rockwell's new MCNS solution includes the company's first single-chip MCNS-compliant Quadrature Amplitude Modulation (QAM) receiver (based on third generation QAM technology), designated the HM2214, which integrates A/D, QAM demodulation and Forward Error Correction (FEC) functions. The new solution also includes two other devices, the HM2314 Quadrature Phase Shift Key (QPSK)/QAM Burst Modulator and the HM8416 Media Access Controller (MAC).
''This highly integrated chipset provides our OEM customers with a complete, easy to integrate silicon solution for a fully-compliant MCNS cable modem,'' said Jay Kshatri, director of broadband modems for Rockwell. ''We also offer evaluation boards and a complete turn-key MCNS two-way modem reference design to help our customers achieve rapid time to market.''
The company's previous generation of cable modem ICs have been selected by New Media Communications (now a subsidiary of Harmonic Lightwaves Corp.), 3COM Corp., NEC, Panasonic, and Daewoo.
Notice that New Media,Panasonic,and Daewoo,are 3 of these companies. I read that HLIT is getting a large shipment of these modem chipsets in the summer quarter.
