ULPI increases interoperability of USB components
Direct-conversion silicon tuner
Leading names in Universal Serial Bus (USB) connectivity have joined
forces to develop a new transceiver interface standard for Hi-Speed
USB 2.0 that reduces development time, increases design flexibility
and ensures interoperability.The UTMI+ Low Pin Interface (ULPI)
provides a standard interface for host, peripheral and On-The-Go (OTG)
functionality.This cuts the transceiver pin-count from over 100 to as low
as 24 and enables the use of much smaller packages. A key player in
creating the ULPI specification, Philips offers the first ULPI-compliant
USB transceivers – the ISP150x family.
USB is the most widely deployed wired connection interface in the PC domain. The recent
USB 2.0 and OTG developments are expanding the applicability of USB by significantly
increasing transfer rates and adding point-to-point communications.The ULPI specification
is a physical implementation of the USB 2.0 Transceiver Macrocell Interface Plus (UTMI+),
which Philips was heavily involved in promoting, and covers host, device and OTG applications.
It allows designers to easily connect a Hi-Speed USB transceiver to USB core logic embedded
in application-specific integrated circuits (ASICs) and System-on-Chip (SoC) solutions.
The ULPI specification provides a standard 12-pin interface between embedded host,
peripheral or OTG circuitry and an external transceiver. As a result, more USB functionality
can be designed in, pin-count can be dramatically cut and packages as small as 4 mm x 4 mm
can be used. By employing the ULPI standard instead of the proprietary interfaces used today,
ASIC and SoC designers can reduce design time, simplify testing and ensure interoperability
with USB transceivers.
A leading provider of silicon solutions for broadband communications,
Broadcom is joining forces with Philips to create next-generation direct-
conversion silicon tuners. Direct conversion has numerous advantages
over existing technologies, allowing cable modem manufacturers to
implement cost-effective, very-low-power tuner designs. Under this
joint development program, Philips will exclusively supply Broadcom
with a new direct-conversion silicon tuner solution for cable modem
applications. Broadcom will implement this technology in a single-chip
product – the BCM3419.
Direct-conversion silicon tuner technology offers significant advantages over the dual- and
single-conversion tuners used in existing cable modems. By eliminating expensive SAW filters,
this advanced technology reduces the design complexity and the cost of implementing tuner
designs. And direct-conversion tuner technology is opening the door to emerging cable
modem applications. For example, the lower power and cost demands deliver the precise
design benefits required by outdoor wireless access points and Voice-over-IP (VoIP) via cable.
Industry’s first Hi-Speed USB host controllers
Philips has delivered the industry’s first Hi-Speed Universal Serial
Bus (USB) host controllers for embedded systems.The two new
devices are the ISP1760 host controller and the ISP1761 single-chip
host and peripheral controller with USB On-the-Go (OTG) support.
They both feature high throughput and low power consumption,
enabling bandwidths up to 480 Mbit/s – the maximum offered by the
USB 2.0 specification.
These new Hi-Speed USB controllers allow people to connect to information,
entertainment and services more quickly and conveniently. The ISP1760 is designed for
set-top boxes, digital televisions, DVD recorders and other consumer products. It offers
high-speed USB connection to PC peripherals such as printers, hard disk drives, memory
cards and scanners. The single-chip ISP1761 includes Hi-Speed capability for both the
device and host function. It is OTG-capable, providing point-to-point communication
between portable devices such as mobile handsets, PDAs, digital still cameras, digital
video cameras and MP3 players.
“Philips is the first to deliver high-performance, Hi-Speed USB and Hi-Speed USB OTG
solutions that will change the way people transfer information and digital content,”
said Dave Sroka, director of marketing at Philips Semiconductors. “Given the boom of
connected consumer devices, the ISP176x family of USB solutions can transform PDAs,
The specification was developed by the ULPI working group, a consortium of leading
semiconductor and IP providers. Chaired by Philips, the working group also comprises ARC
International, Conexant, Mentor Graphics, TransDimension Inc. and Standard Microsystems
Corporation (SMSC). In addition, Cypress, Synopsys, Innovative Semiconductors and
Motorola have recently verified the specification and joined the working group.
“We are delighted to continue our close working relationship with Philips Semiconductors,”
said Michael Kaskowitz, General Manager of the Mentor Graphics Intellectual Property
division. “Proving the interoperability of our intellectual property with the ISP150x family
will be a major factor in easing the adoption of Hi-Speed USB in today’s sophisticated
embedded devices.”
Intimately involved in creating the specification, Philips had first-hand knowledge of any
modifications. Consequently it could develop transceivers in parallel with the standard, and
so was the first company to bring ULPI-compliant products to market.The 32-pin ISP1504
provides full host, peripheral and OTG functionality, while the 24-pin ISP1505 is designed for
stand-alone hosts and peripheral applications. Finally, the 24-pin ISP1506 is a fully featured host,
peripheral and OTG transceiver that brings double-data-rate operation to mobile applications.
digital cameras or smart phones into
centers of connectivity.”
Power consumption is especially
important for portable devices. The
ISP176x family features a power-
optimized architecture for low power
consumption in both operating and
suspend modes. A hybrid power-down
mode also allows the USB devices to
be powered from both the USB cable
and the system power supply. When this
power reallocation is utilized, the power
consumption of the ISP1761 or ISP1760
from the board supply is reduced by
over 40%.
“The technology demands for cable modems are changing to reflect the growing number
of uses seen by cable operators, including line-powered or battery-backed voice modems,”
said Dan Marotta,Vice President of Broadcom’s Broadband Communications Group.
“Working with Philips on this next-generation tuner technology will allow our customers
to support a growing number of cable modem applications that are not possible today
with dual-conversion tuners. An immediate benefit of using direct-conversion technology
in the BCM3419 chip is the improved market competitiveness the product can offer our
customers. This advanced silicon solution cuts the number of tuner support components
in half and reduces the time and complexity of manufacturing.”
The BCM3419 is the cable modem industry’s first single-chip, direct-conversion tuner solution.
It supports both current requirements for Quadrature Amplitude Modulation (QAM), as well
as advanced orders of QAM used by many of Broadcom’s chips. The advanced capabilities
in the BCM3419 result in improved product performance and reliability and fewer system
support components. The BCM3419 also allows customers to reduce the bill of materials
(BOM) for existing cable modems.
