Arasan Chip Systems, Inc., has introduced the
company's USB 2.0 PHY IP. The USB 2.0 PHY comprises a complete on-chip
physical transceiver solution optimized for low power consumption,
minimal die area, and high data throughput.
The USB 2.0 PHY features fully integrated Electrostatic
Discharge (ESD) protection, full support for OTG, device, hub and host
The core was developed by Mentor Graphics Corporation and proven in
silicon in the SMIC 130 nm process. Arasan has licensed the complete
core and associated technology from Mentor Graphics and Arasan will
support and develop the technology using its own analog mixed signal
"Acquiring this high-quality silicon-proven PHY core that successfully
passed the USB plug-fest process has saved us a tremendous amount of
development time." said Prakash Kamath, Vice President of Engineering
for Arasan. "Demand for USB 2.0 products continues to be robust."
"For reasons unrelated to the USB market, we decided that the USB PHY
business was not consistent with Mentor's overall strategy. We are
pleased to have Arasan carrying this technology and our investment
legacy forward." said Aaik van der Poel, Business Unit Manager,
Continuing Products Division, Mentor Graphics. "During the development
effort we carefully constructed this IP to be compatible with standard
CMOS processes for ease of porting and qualified it through the USB-IF
plug fest methodology."
The Arasan USB 2.0 PHY IP core is a high speed USB transceiver for use
with host, embedded host, On-the-Go (OTG) and function controllers.
Compliant with the USB 2.0 Transceiver Macrocell Interface Plus (UTMI+)
level 3 specification, the Arasan USB 2.0 PHY integrates high speed
mixed-signal circuits to support USB High-Speed (HS) traffic at 480 Mbps
and is backward-compatible with 12 Mbps Full-Speed (FS) and 1.5 Mbps
Low-Speed (LS) data rates.
The USB 2.0 PHY IP is delivered in a GDSII format targeted for a
specific process technology library. Because the design was done with
standard CMOS process technology in mind it can easily be ported to many
foundry/process technology combinations.
The USB 2.0 PHY joins the suite of other Arasan USB products including
USB 2.0 Device, Hub, OTG, embedded Host, HSIC PHY and USB 3.0
The Arasan USB 2.0 PHY IP solution, including IP core, verification IP and documentation is available immediately for licensing.
