SCSI technology enters the seventh generation
LSI Logic has announced commercial availability of the LSI53C1030 Ultra320 SCSI controller chip and the start of a worldwide product sampling and demo program featuring LSI Logic's Ultra320 products.
"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 highly integrated design eliminates factory calibration, enhances reliability, and reduces bill of material and overall costs.
The chip reduces the component count to less than 30 and dissipates 600mW in full power mode running off a single 3.3V power supply.
This is a significant improvement over typical tuner solutions that have several hundred components, dissipate 1.5 to 2.5W and require multiple power sources of 3 to 30V.
The Hi-IQ tuner supports DOCSIS and DAVIC applications.
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 and is priced at $7.40 in quantities of 10,000.
Samples are available now with production quantities due in Q1, 2002.
