LSI Logic Introduces Single-Chip Cable Modem Tuner

Flagship RF Product Drives Convergence Technologies (September 24, 2001)
LSI Logic Corporation today introduced an integrated cable tuner/receiver chip, the company's flagship product in its new wideband radio frequency (RF) VLSI product line. Initially designed for use in cable modems, the Hi-IQ tuner, DPS7000, completely integrates all critical RF elements onto a single device to meet the price, power and size requirements of the cable broadband access market.

"LSI Logic's RF strategy is designed to address the imminent communications convergence," said Phil Welsh, director of marketing for LSI Logic's Broadband Access division. "By offering a small, low-power tuner that is essential in cable-based broadband access devices and cable telephony applications, we're empowering mainstream markets where pricing is paramount, as well as growing markets, such as Voice over IP, where low power is critical."


LSI Logic created the Hi-IQ tuner to address the industry's demanding market requirements. By eliminating components that require adjustments after shipping, the integrated design eliminates factory calibration, enhances reliability, and reduces bill of material and overall costs. The chip reduces the component count to less than thirty and dissipates 600mW in full power mode running off a single 3.3-volt power supply. This is a significant improvement over typical tuner solutions that have several hundred components, dissipate 1.5 to 2.5 W and require multiple power sources of 3- to 30-volts. The Hi-IQ tuner supports DOCSIS and DAVIC applications.

"The RF tuner market has great potential given the surge in popularity for digital consumer electronics devices that require tuners," according to Mike Paxton, a multimedia analyst at Cahners In-Stat Group. "Tuners like the Hi-IQ DPS7000, that can significantly reduce costs through high levels of reliability and integration, will further strengthen demand for cable modems, set-top boxes, PVRs and other convergence applications within the home."

The Hi-IQ tuner is the first product in LSI Logic's wideband RF offering, with future products mapped for applications including set-top boxes, digital televisions, digital video recorders and wireless LANs. The chip complements LSI Logic's line of cable-based products, which includes the MultiLynx 2161 and 2151 universal cable transceivers, offering designers total solutions for cable-modem and set-top box applications.

Price and availability
The DPS7000 Hi-IQ tuner is provided in a single 64-pin TQFP package and is priced at $7.40 in quantities of 10,000. Samples are available now with production quantities in Q1, 2002.
