Sony's i.LINK LSI Chips Among the First Connecting
Storage Devices, Set-Top Boxes and Digital TV to IEEE
1394
SAN JOSE, Calif.--(BUSINESS WIRE)--Nov. 24, 1997--
Virtuoso Devices Link Digital and MPEG-2 Peripherals to High Speed Serial Bus Standard
Sony Semiconductor Co. of America (SSA), a division of Sony Electronics Inc., Monday
announced two LINK layer LSIs designed to connect peripherals in IEEE 1394 environments.
The CXD1948R supports MPEG-2 streams for set-top boxes, digital television and other DVB
(digital video broadcasting) and DSS (digital satellite system) applications. The CXD3220R
supports SBP-2 (serial bit protocol 2), a new disk drive industry standard for storage applications.
These chips are part of Sony's worldwide based i.LINK products for IEEE 1394 and are among the
first available supporting the emerging standard. The new members of the Virtuoso family enable the
next generation of consumer electronics and computer products to operate in a common
environment. The Virtuoso family consists of Sony's new line of digital media devices.
"Compatibility with the IEEE 1394 standard will make the next generation of consumer electronic
products more computer friendly and the next generation of computer products more attractive to
consumers," said Vishwanath Nayak, director of marketing consumer a/v/d products for SSA.
"Sony's LINK LSIs incorporate key enabling technologies that will lead to a diverse array of
innovative products in the new millennium."
The IEEE 1394 serial bus is a new connectivity standard key to connecting high-bandwidth
consumer products with PC systems. This inexpensive, easy-to-use and high-speed bus easily
handles multimedia bandwidth requirements and will serve as a universal interface for computer
peripherals and consumer electronic devices.
IEEE 1394 uses thin, flexible, durable cables and simple connectors to allow up to 63 devices to
share a single bus in a daisy-chain or tree configuration. It can carry multiple channels of isochronous
and asynchronous data simultaneously.
Isochronous capabilities enable the bus to handle real-time data, digital audio and video streams,
while the asynchronous capabilities control traditional forms of information between devices.
Combined, these capabilities support all the necessary data flow required to optimize the use of
peripheral devices such as video cameras, CD-ROM drives, printers, storage devices, camcorders,
VCRs or set-top boxes.
Supporting DVB (188 byte) and DSS (130/140 byte) transport streams, the CXD1948R conforms
to the IEEE 1394-1995 standard and supports the AV protocol. The chip includes dedicated ports
for 8-bit and 16-bit asynchronous and isochronous data. During transmission, the CXD1948R time
stamps the MPEG-2 stream, converts it to IEEE 1394 format and sends it to the IEEE 1394 chip.
It also automatically recovers time stamps during reception by keeping the IEEE 1394 data in a
built-in FIFO and synchronizing it to the time stamp value and output.
The CXD1948R supports data transfer rates of 100 and 200Mbps. It provides both a host interface
(asynchronous) and a TPS interface (isochronous). An on-board insert FIFO enables isochronous
transfers from the host.
The CXD3220R comes standard with an asynchronous data page (ADP) circuit that automatically
generates SBP-2 packets through the transaction layer instead of through software. It supports data
transfer rates of 100 and 200Mbps and includes a 2KB FIFO for data transfers, a 96-byte FIFO
for asynchronous transfers and a 156-byte FIFO for reception. Both 8-bit and 16-bit interfaces are
provided for CPU and transport data.
Both silicon gate CMOS ICs are packaged as 100-pin, plastic LQFPs. The CXD3220R is available
now in sample quantities, with pricing starting at $24 each. In June 1998, 1000-unit quantities will be
available for an anticipated price of $14 each. The CXD1948R is available now in sample quantities,
with pricing starting at $24 each. In December of 1997, 1000-unit quantities will be available for an
anticipated price of $16 each.
