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.
The higher datarate enabled by the ADSL2+ standard is capable of doubling the downstream datarates to over 20Mbit/s over loops shorter than 2.5km, allowing for delivery of superior broadband services such as DVD-quality broadband content and video-on-demand.
"The DSL market is striving to increase the availability of service and retain customers with new applications, and ADSL2+ is a logical and welcome step", said Mike Wolf, Principal Analyst, Consumer Content and Connectivity, In-Stat/MDR.
"With today's need for time-to-market and restrained design resources, system designers are looking for highly integrated solutions, and LSI Logic is offering direct savings to their bottom line.

The ADSL2+ HomeBase solution offers manufacturers unique flexibility and performance capabilities to help service providers deliver a more comprehensive offering of enhanced broadband services such as home networking and gaming".
The HomeBase AR902 ADSL2+ Ethernet network processor integrates the DMT engine with a 200MHz ARM922 processor, a hardware-based ATM SAR, a USB port and a SDRAM controller that provides the network processor with access to high-bandwidth, high-capacity bulk memory.
The high level of integration of the AR902 significantly reduces the overall system bill-of-materials of ADSL modem manufacturers.
The HomeBase AR922 ADSL2+ SOHO network processor integrates an ARM1026 running at 250MHz with DDR SDRAM and NAND Flash support, plus a crypto coprocessor providing hardware acceleration for IPSEC applications and is especially well suited for residential gateways.
The AR922 has two Ethernet ports, a USB master and separate USB slave interface.
For customers requiring an alternate configuration, the HomeBase AR942 replaces the two Ethernet ports with an internal five-port switch.
Both the AR922 and AR942 feature a PCI bus for further expansion including glueless connection to mini-PCI 802.11a/b/g WiFi chipsets.
The new HomeBase ADSL2+ network processors connect to the AR8204; a sixth-generation SpeedReach analogue front end (AFE) that is compatible with all ADSL standards including the 2.2MHz ADSL2+ standard and all annexes of the ADSL2+ via flexible on-chip analogue filtering.
The AR8204 contains an integrated 5V line driver and a 14bit linear analogue-to-digital plus digital-to-analogue convertor.
The AFE's input referred noise floor of -160dBm/Hz is the lowest in the industry.
The performance advantage of the AFE helps to build a robust and high-performance modem with higher datarates and extended reach.
"Our new family of HomeBase ADSL2+ chipsets adds features and functionality that will help drive the success of this new standard in the global market", said Steve Ellwood, Director of DSL Product Marketing, LSI Logic.
"By offering a spectrum of two-chip solutions that are cost-effective, scalable and flexible, we are giving telcos the performance they need to get to market quickly with products that support new applications, services and deployment scenarios like the distribution of software and video".
The new network processors are fully software compatible with previous HomeBase devices and backward compatible to the ADSL standard.
LSI Logic offers a choice of operating systems, including Windows CE, VX Works and the royalty-free Linux operating system.
LSI Logic HomeBase solutions include all the hardware and software needed for bridge, router or gateway functionality.
The HomeBase ADSL2+ chipsets (includes the SpeedReach AFE AR8204) will be sampling in December.
