Mindspeed Expands Industry’s Largest Family of Signal Conditioners with Integrated Crosspoint Switches

Business Wire
Mindspeed Technologies, Inc. (NASDAQ: MSPD), a leading
supplier of semiconductor solutions for network infrastructure
applications, today expanded its signal conditioner family with
four new Clock and Data Recovery (CDR) devices that are unique in
including an integrated, non-blocking crosspoint that can be used
for redundancy or protection switching, enabling the devices to
handle system switching and signal integrity requirements in a
single device. The products use Mindspeed®’s Amplif-Eye™ signal
conditioning technology to send error-free data at high data rates
across difficult channels in next-generation carrier and enterprise
systems, for applications such as high-bandwidth Optical Transport
Network (OTN) switches and access equipment required for the
upcoming worldwide 10 Gbit/s Ethernet Passive Optical Network
(10-GEPON) rollout.
Mindspeed’s new re-timing signal conditioners combine
high-performance equalizers, CDRs and a crosspoint in a single,
integrated solution. The eight-channel M21440 and 12-channel M21441
devices support up to 10.3125Gb/s data rates for protocols,
including 10GbE, 8G Fibre Channel and PCIe, and feature both an
integrated linear equalizer and a Decision Feedback Equalizer (DFE)
in the input stage that, combined with the CDR, compensate for
backplane signal reflections and transmitter noise. The company
also has announced the eight-channel M21462 and 12-channel M21463
devices, which solve signal integrity issues for systems using
RXAUI over backplanes, systems sending PCIe or Serial Attached
SCSI/Serial Advanced Technology Attachment (SAS/SATA) data over
difficult channels, and systems using proprietary data rates up to
6.25Gb/s.
Key product features include:
- M21440 and M21441: These devices
are optimal for applications requiring transmission of 10Gb/s over
a backplane, and support many standards up to 10.3125Gb/s, as well
as non-standard and proprietary data rates. The CDR can
automatically detect and lock to the input data rate, allowing
support for legacy versions of protocols without user intervention,
such as detecting between the data rates of Peripheral Component
Interconnect Express (PCIe) generation 1, 2 and 3. Both equalizer
blocks are fully adaptive, which shortens design cycles and allows
the device to accommodate changing channel conditions. The
programmable output driver includes post-tap and pre-tap
de-emphasis, and the devices also include a pseudo-random binary
sequence (PRBS) generator and checker that support PRBS31 patterns.
An eye mapper feature shows the eye contour after equalization and
can be customized for either eye resolution or capture time.
- M21462 and M21463: These devices
support data rates up to 6.25Gb/s and can solve signal integrity
issues for systems using RXAUI over backplanes, systems sending
PCIe or SAS/SATA data over difficult channels and systems using
proprietary data rates. Pin compatibility with Mindspeed’s M21452
and M21453 non-retimed equalizer devices gives developers the
flexibility to use either an equalizer or equalizer with CDR
solution, without having to make any changes to the hardware.
Mindspeed’s new CDRs also expand the company’s extensive
crosspoint portfolio, which spans channel counts from two to 288.
In addition to enabling redundancy switching and easing routing
constraints, the integrated crosspoints also enable loopback on any
channel to aid in system test and debugging. Mindspeed’s crosspoint
architecture is designed for applications requiring switching with
ultra-low latency, such as financial trading. The latency through
the device is less than 1.5 nanoseconds (ns), which can make a
crucial difference in executing trades.
The 10.3125Gb/s M21440 and M21441 CDRs with adaptive equalizer
and crosspoint are sampling now, with production scheduled for the
second quarter of 2012. The 6.25Gb/s M21462 and M21463 CDRs with
crosspoint switching are available now and are released to
production.
