New Line of SMSC Energy Efficient Ethernet Transceivers Delivers Significant Power Savings
June 27 2012 - 8:00AM
Business Wire
SMSC (NASDAQ: SMSC), a leading semiconductor company enabling
content-rich connectivity systems, today launched a family of
energy-efficient, low power 10/100 Ethernet Physical Layer
Transceivers (PHYs) for consumer, industrial and enterprise
hardware applications. The LAN8740, LAN8741 and LAN8742 offer up to
50 percent lower power consumption than existing SMSC transceivers.
Primary applications include set-top boxes, digital video
recorders, network printers and servers, IP and video phones,
digital televisions, industrial control and embedded systems. In
its more than 15 years of designing networking products, SMSC has
shipped over 250 million Ethernet ports and is relied upon by a
global customer base as a single supplier of a variety of
networking products designed to work with a broad range of device
architectures.
The LAN8740 and LAN8741 implement the IEEE 802.3az Energy
Efficient Ethernet standard directly into the physical layer. IEEE
802.3az is an amendment to the IEEE 802.3 Ethernet standard,
defining mechanisms and protocols intended to reduce the energy
consumption of network links during periods of low utilization, by
transitioning interfaces into a low-power state. The LAN8742
implements a “Wake on LAN” mode, which allows systems to enter a
low power state and wake on desired network traffic, thereby
conserving resources during downtimes. These innovations allow
customers to upgrade their existing systems for greater energy
efficiency simply by changing the Ethernet PHY.
“There is a fast growing demand to conserve system power in
nearly all networked systems,” said Rolf Mahler, Vice President and
General Manager of SMSC’s Industrial and Networking Group. “SMSC
addresses this demand through implementation of the Energy
Efficiency Ethernet specifications. Now, we are taking these
solutions a step further with a more intelligent PHY that allows
the system to enter low power sleep states while monitoring select
data traffic with ‘Wake On LAN’ functionality. In addition, the
LAN874x family introduces cable diagnostics capabilities to detect
and troubleshoot cable issues as well as deterministic latency for
precision timing of data delivery. The result is a family of
transceivers that provide an extraordinarily feature-rich,
environment-friendly set of Ethernet connectivity solutions.”
The LAN8740, LAN8741 and LAN8742 PHYs have an integrated voltage
regulator and ESD protection components. The MAC interface supports
flexible I/O voltages from 1.6V to 3.6V required by higher
performance ASICs, SoCs and FPGAs which continue to migrate to
lower geometry processes requiring lower I/O voltage support. The
LAN874x family of devices provides support for flexible I/O voltage
to enable a highly optimized system design. The LAN8740, LAN8741
and LAN8742 offer the flexibility of disabling on-chip regulators
to reduce system power consumption.
In addition to standard features such as IEEE 802.3/802.3u
compliance, UNH interoperability certification, HP Auto-MDIX
support and MII/RMII interfaces, the LAN8740, LAN8741 and LAN8742
PHYs deliver additional features:
- SMSC’s flexPWRTM technology for low
power consumption & variable I/O voltage support
- Cable diagnostics for reporting of
cable faults and proactive system maintenance
- Deterministic latency for precision
timing in Industrial applications
- Single 25MHz Crystal design
- Operation over extended commercial (0
to 70 degree C) and industrial (-40 to 85 degree C) temperature
ranges
- Compact 5x5mm 32QFN (LAN8740, LAN8741)
and 4x4mm 24QFN (LAN8742) RoHS compliant packages
Additionally, SMSC provides an easy migration path from current
LAN8710 and LAN8720 transceivers to the new LAN8740, LAN8741 and
LAN8742 transceivers with minimal redesign efforts. SMSC offers one
of the broadest families of Ethernet connectivity solutions in the
industry, which include stand-alone transceivers, MAC controllers,
integrated single-chip MAC+PHY products, switches and USB to
Ethernet bridges.
The LAN8740, LAN8741 and LAN8742 samples and evaluation kits are
available now with mass production slated for later in 2012.
Pricing will range from $0.69 to $0.95 in volume production.
