GENEVA -- STMicroelectronics Inc. here today jumped into the emerging cable-modem chip business, announcing an integrated product that complies with the Data Over Cable Service Interface Specification (DOCSIS) standard.
The product will put ST in a growing but competitive market. Other suppliers of cable-modem chip include Broadcom, C-Cube, Conexant, Intel, and Texas Instruments.
ST's new device, the STV0396, will integrate several functions in the same device, including a DOCSIS version 1.0/1.1-compliant physical-layer (PHY) IC, media-access controller (MAC), a 32-bit microcontroller with integrated instruction and data cache, 8-Kbytes of embedded SRAM, and interfaces to customer premises equipment (CPE).
The MAC engine is the result of a joint technology cooperation with Scientific Atlanta Inc., one of the world's leading suppliers of interactive digital set-top boxes, interactive networks and broadband access equipment.
Based on a 0.18-micron process, the STV0396 will be offered in a 316-pin PBGA package. Engineering samples will be available for the first quarter of 2001, with volume production slated for the second half of 2001.
ST will also offer a complete DOCSIS 1.1-compliant reference design kit to OEMs. Prices for the chip will not given, but ST said OEMs could develop a cable-modem product for less than $85 with its IC.
